Quantification of operating reserves with high penetration of wind power cons...IJECEIAES
The high integration of wind energy in power systems requires operating reserves to ensure the reliability and security in the operation. The intermittency and volatility in wind power sets a challenge for day-ahead dispatching in order to schedule generation resources. Therefore, the quantification of operating reserves is addressed in this paper using extreme values through Monte-Carlo simulations. The uncertainty in wind power forecasting is captured by a generalized extreme value distribution to generate scenarios. The day-ahead dispatching model is formulated as a mixed-integer linear quadratic problem including ramping constraints. This approach is tested in the IEEE-118 bus test system including integration of wind power in the system. The results represent the range of values for operating reserves in day-ahead dispatching.

Improving the efficiency of photovoltaic cells embedded in floating buoysIJECEIAES
Solar cells are used to power floating buoys, which is one of their applications. Floating buoys are devices that are placed on the sea and ocean surfaces to provide various information to the floats. Because these cells are subjected to varying environmental conditions, modeling and simulating photovoltaic cells enables us to install cells with higher efficiency and performance in them. The parameters of the single diode model are examined in this article so that the
I-V, P-V diagrams, and characteristics of the cadmium telluride (CdTe) photovoltaic cell designed with three layers (CdTe, CdS, and SnOx) can be extracted using a solar cell capacitance simulator (SCAPS) software, and we obtain the parameters of the single diode model using the ant colony optimization (ACO) algorithm. In this paper, the objective function is root mean square error (RMSE), and the best value obtained after 30 runs is 5.2217×10-5 in 2.46 seconds per iteration, indicating a good agreement between the simulated model and the real model and outperforms many other algorithms that have been developed thus far. The above optimization with 200 iterations, a population of 30, and 84 points was completed on a server with 32 gigabytes of random-access memory (RAM) and 30 processing cores.

A Utility Interactive Electricity Generation Schemes with Renewable ResourcesIOSR Journals
Abstract: In the recent year’s power utility of coastal areas are experiencing relatively large quantum of solar and wind energy. If the wind is heavy it might produce larger sea waves of high energy contents. The electricity needs of a township or a village situated in a coastal area can be partially fulfilled by installing a modular mini electricity generating unit and an intensified solar heat extractor in buildings. Also, installation of medium sized windmill plant, solar heated steam turbine electricity generator and sea wave energy extracting plants could fulfill the rest of the electricity needs of the township. Here we discuss the regulation of the voltage and frequency of a stand-alone fixed-pitch wind energy conversion system (WECS) based on a self-excited squirrel-cage induction machine. The characteristics of the wind turbine, self-excited generator, and the ratings of the VSI are considered in order to determine the load range for which voltageand frequency can be regulated for a given wind speed range. Keywords: Solar panel, solar tracker, solar water heater,renewable energy, wind mills, induction generator, load management.

Sizing of Hybrid PV/Battery Power System in Sohag cityiosrjce
This paper gives the feasibility analysis of PV- Battery system for an off-grid power station in Sohag
city. Hybrid PV-battery system was used for supplying a combined pumping and residential load. A simple cost
effective method for sizing stand-alone PV hybrid systems was introduced. The aim of sizing hybrid system is to
determine the cost effective PV configuration and to meet the estimated load at minimum cost. This requires
assessing the climate conditions which determine the temporal variation of the insolation in Sohag city. Sizing
of the hybrid system components was investigated using RETscreen and HOMER programs. The sizing software
tools require a set of data on energy resource demand and system specifications. The energy cost values of the

The Impact of Digital Media on the Decentralization of Power and the Erosion ...ijtsrd
The impact of digital media on the distribution of power and the weakening of traditional gatekeepers has gained considerable attention in recent years. The adoption of digital technologies and the internet has resulted in declining influence and power for traditional gatekeepers such as publishing houses and news organizations. Simultaneously, digital media has facilitated the emergence of new voices and players in the media industry. Digital medias impact on power decentralization and gatekeeper erosion is visible in several ways. One significant aspect is the democratization of information, which enables anyone with an internet connection to publish and share content globally, leading to citizen journalism and bypassing traditional gatekeepers. Another aspect is the disruption of conventional media industry business models, as traditional organizations struggle to adjust to the decrease in advertising revenue and the rise of digital platforms. Alternative business models, such as subscription models and crowdfunding, have become more prevalent, leading to the emergence of new players. Overall, the impact of digital media on the distribution of power and the weakening of traditional gatekeepers has brought about significant changes in the media landscape and the way information is shared. Further research is required to fully comprehend the implications of these changes and their impact on society.

Comparative Analysis of Total Corporate Disclosure of Selected IT Companies o...ijtsrd
Disclosure is a process through which a business enterprise communicates with external parties. A corporate disclosure is communication of financial and non financial information of the activities of a business enterprise to the interested entities. Corporate disclosure is done through publishing annual reports. So corporate disclosure through annual reports plays a vital role in the life of all the companies and provides valuable information to investors. The basic objectives of corporate disclosure is to give a true and fair view of companies to the parties related either directly or indirectly like owner, government, creditors, shareholders etc. in the companies act, provisions have been made about mandatory and voluntary disclosure. The IT sector in India is rapidly growing, the trend to invest in the IT sector is rising and employment opportunities in IT sectors are also increasing. Therefore the IT sector is expected to have fair, full and adequate disclosure of all information. Unfair and incomplete disclosure may adversely affect the entire economy. A research study on disclosure practices of IT companies could play an important role in this regard. Hence, the present research study has been done to study and review comparative analysis of total corporate disclosure of selected IT companies of India and to put forward overall findings and suggestions with a view to increase disclosure score of these companies.

The Role of Mentoring and Its Influence on the Effectiveness of the Teaching ...ijtsrd
This paper reports on a study which was conducted to investigate the role of mentoring and its influence on the effectiveness of the teaching of Physics in secondary schools in the South West Region of Cameroon. The study adopted the convergent parallel mixed methods design, focusing on respondents in secondary schools in the South West Region of Cameroon. Both quantitative and qualitative data were collected, analysed separately, and the results were compared to see if the findings confirm or disconfirm each other. The quantitative analysis found that majority of the respondents 72 of Physics teachers affirmed that they had more experienced colleagues as mentors to help build their confidence, improve their teaching, and help them improve their effectiveness and efficiency in guiding learners’ achievements. Only 28 of the respondents disagreed with these statements. With majority respondents 72 agreeing with the statements, it implies that in most secondary schools, experienced Physics teachers act as mentors to build teachers’ confidence in teaching and improving students’ learning. The interview qualitative data analysis summarized how secondary school Principals use meetings with mentors and mentees to promote mentorship in the school milieu. This has helped strengthen teachers’ classroom practices in secondary schools in the South West Region of Cameroon. With the results confirming each other, the study recommends that mentoring should focus on helping teachers employ social interactions and instructional practices feedback and clarity in teaching that have direct measurable impact on students’ learning achievements.

This study primarily focuses on the design of a high side buck converter using an Arduino microcontroller. The converter is specifically intended for use in DC DC applications, particularly in standalone solar PV systems where the PV output voltage exceeds the load or battery voltage. To evaluate the performance of the converter, simulation experiments are conducted using Proteus Software. These simulations provide insights into the input and output voltages, currents, powers, and efficiency under different state of charge SoC conditions of a 12V,70Ah rechargeable lead acid battery. Additionally, the hardware design of the converter is implemented, and practical data is collected through operation, monitoring, and recording. By comparing the simulation results with the practical results, the efficiency and performance of the designed converter are assessed. The findings indicate that while the buck converter is suitable for practical use in standalone PV systems, its efficiency is compromised due to a lower output current.

Sustainable Energy by Paul A. Adekunte | Matthew N. O. Sadiku | Janet O. Sadikuijtsrd
Energy becomes sustainable if it meets the needs of the present without compromising the ability of future generations to meet their own needs. Some of the definitions of sustainable energy include the considerations of environmental aspects such as greenhouse gas emissions, social, and economic aspects such as energy poverty. Generally far more sustainable than fossil fuel are renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy sources. Worthy of note is that some renewable energy projects, like the clearing of forests to produce biofuels, can cause severe environmental damage. The sustainability of nuclear power which is a low carbon source is highly debated because of concerns about radioactive waste, nuclear proliferation, and accidents. The switching from coal to natural gas has environmental benefits, including a lower climate impact, but could lead to delay in switching to more sustainable options. “Carbon capture and storage” can be built into power plants to remove the carbon dioxide CO2 emissions, but this technology is expensive and has rarely been implemented. Leading non renewable energy sources around the world is fossil fuels, coal, petroleum, and natural gas. Nuclear energy is usually considered another non renewable energy source, although nuclear energy itself is a renewable energy source, but the material used in nuclear power plants is not. The paper addresses the issue of sustainable energy, its attendant benefits to the future generation, and humanity in general. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.

Concepts for Sudan Survey Act Implementations Executive Regulations and Stand...ijtsrd
This paper aims to outline the executive regulations, survey standards, and specifications required for the implementation of the Sudan Survey Act, and for regulating and organizing all surveying work activities in Sudan. The act has been discussed for more than 5 years. The Land Survey Act was initiated by the Sudan Survey Authority and all official legislations were headed by the Sudan Ministry of Justice till it was issued in 2022. The paper presents conceptual guidelines to be used for the Survey Act implementation and to regulate the survey work practice, standardizing the field surveys, processing, quality control, procedures, and the processes related to survey work carried out by the stakeholders and relevant authorities in Sudan. The conceptual guidelines are meant to improve the quality and harmonization of geospatial data and to aid decision making processes as well as geospatial information systems. The established comprehensive executive regulations will govern and regulate the implementation of the Sudan Survey Geomatics Act in all surveying and mapping practices undertaken by the Sudan Survey Authority SSA and state local survey departments for public or private sector organizations. The targeted standards and specifications include the reference frame, projection, coordinate systems, and the guidelines and specifications that must be followed in the field of survey work, processes, and mapping products. In the last few decades, there has been a growing awareness of the importance of geomatics activities and measurements on the Earths surface in space and time, together with observing and mapping the changes. In such cases, data must be captured promptly, standardized, and obtained with more accuracy and specified in much detail. The paper will also highlight the current situation in Sudan, the degree to which survey standards are used, the problems encountered, and the errors that arise from not using the standards and survey specifications.

Towards the Implementation of the Sudan Interpolated Geoid Model Khartoum Sta...ijtsrd
The discussions between ellipsoid and geoid have invoked many researchers during the recent decades, especially during the GNSS technology era, which had witnessed a great deal of development but still geoid undulation requires more investigations. To figure out a solution for Sudans local geoid, this research has tried to intake the possibility of determining the geoid model by following two approaches, gravimetric and geometrical geoid model determination, by making use of GNSS leveling benchmarks at Khartoum state. The Benchmarks are well distributed in the study area, in which, the horizontal coordinates and the height above the ellipsoid have been observed by GNSS while orthometric heights were carried out using precise leveling. The Global Geopotential Model GGM represented in EGM2008 has been exploited to figure out the geoid undulation at the benchmarks in the study area. This is followed by a fitting process, that has been done to suit the geoid undulation data which has been computed using GNSS leveling data and geoid undulation inspired by the EGM2008. Two geoid surfaces were created after the fitting process to ensure that they are identical and both of them could be counted for getting the same geoid undulation with an acceptable accuracy. In this respect, statistical operation played an important role in ensuring the consistency and integrity of the model by applying cross validation techniques splitting the data into training and testing datasets for building the geoid model and testing its eligibility. The geometrical solution for geoid undulation computation has been utilized by applying straightforward equations that facilitate the calculation of the geoid undulation directly through applying statistical techniques for the GNSS leveling data of the study area to get the common equation parameters values that could be utilized to calculate geoid undulation of any position in the study area within the claimed accuracy. Both systems were checked and proved eligible to be used within the study area with acceptable accuracy which may contribute to solving the geoid undulation problem in the Khartoum area, and be further generalized to determine the geoid model over the entire country, and this could be considered in the future, for regional and continental geoid model.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

where,
δ = the angle between the plane of the equator and a line
drawn from the center of the sun and center of the earth
(varies between extremes of ± 23.45⁰)
βN = altitude angle of the sun at noon
L = latitude angle of the selected location
βN = 90° − L + δ Equation (2)
The tilt angle that would make the sun’s rays perpendicular
to the module at noon would therefore be:
Tilt angle of array, θ = 90° ̶ βN

The number of parallel batteries,

The total number of batteries,

2.1. Determining the Sizing of PV Array
System array size is essential for the calculation of
standalone solar electricity generation system. The more
there is system capacity, the more the module capacity is
selected.
The average peak power,
Pave,peak = kWh/day Equation (13)
where,
Tsh = the peak sun hours (hrs./day)
The total dc current of the system,
Idc = A Equation (14)
The total number of modules,
Ntotal = Equation (15)
The number of modules in series,
Ns= Equation (16)
The number of parallel modules strings,
Np = Equation (17)
Where,
Vdc = the dc voltage of the system
Vrm = the rated voltage of each module
Irm = the rated current of each module
The total number of modules,
Ntotal= Ns × Np Equation (18)
The output power of PV array
= Ntotal × Power of one module Equation (19)
And then, Array rated current
= Np × Impp Equation (20)
Array short-circuit current
= Np ×Isc Equation (21)
Array rated voltage
= Ns × Vmpp Equation (22)
Array opened-circuit voltage
= Ns × Voc Equation (23)
Where,
Isc = the short circuit current
Imp = the current at maximum power point
Vmp = the voltage at maximum power point
Voc = the opened circuit voltage
Minimum Controller Input Current,
Isc,min = Np × Isc × safety factor Equation (24)
This is the input current that comesfromthesolararray.The
number of parallel strings in the array increases thecurrent.
To be on the safe side, it is advised to multiply the result by a
safety factor of 1.25.
2.2. Determination of Cables Size
The wiring must not reduce the performance of any of the
components of the system. The cables in a mini grid
connected system must be sized correctly to reduce the
voltage drops in the cable and to make sure that the safe
current handling capacity of the cable is not exceeded. The
voltage drop in a cable is given as,
ΔV= 2 (L× I × ρ) / A Equation (25)
3. International Journal of Trend in Scientific Research and Development (IJTSRD) @ www.ijtsrd.com eISSN: 2456-6470
@ IJTSRD | Unique Paper ID – IJTSRD25281 | Volume – 3 | Issue – 5 | July - August 2019 Page 215
where,
ρ = the resistivity of copper wire which is normally taken
to be 1.724 × 10-8 Ωm
L = the length of cables in meters
I = the current through the cables in amperes
A = the cross-sectional area in mm2
The multiplication by 2 accounts for total circuit wirelength.
ΔV = Maximum cable voltage drop (5%) ×
system voltage Equation (26)
In the design of the system, a maximum cable voltage drops
of 5% was used that is why the maximum allowable drop in
PV mini grid connected systems.
2.3. Considering System Voltage
Total load demand (W/day) is divided bythesystem voltage.
It is smaller less than 100A.
Thus, Let system voltage be 12V, 18kW/day ÷ 12V
= 1500A > 100A
Let system voltage be 24V, 18kW/day ÷ 24V
= 750A > 100A
Let system voltage be 48V, 18kW/day ÷ 48V
= 375A > 100A
Let system voltage be 96V, 18kW/day ÷ 96V
= 187A > 100A
Let system voltage be 192V, 18kW/day ÷ 192V
= 94A < 100A
Therefore, system voltage 192V is chosen.
2.4. Calculating Inverter Size
Inverter size is important
= Maximum Peak Hour Demand * 1.25
= 55 kW * 1.25 = 68750 W
Therefore, 70 kVA three phase inverter is chosen.
Total load demand (Wh /day)
= Power in Watt × Hours in use
= 428 kWh
Total load demand (Ah/day)
= Total load (kWh/day)
System Voltage Inverter efficiency×
= 2623 Ah/day
Assuming; The efficiency of the inverter is 85%.
2.5. Considering System Losses
The total loads plus the system losses (10%)
= Total Estimated Load (Ah/day) + 10%
= 2623 + 10%
= 2885 Ah/day
2.6. Calculating the Solar Irradiation in Daily
Equivalent Sun Hours
Total sun hours = 2000kWhm-2/1000Wm-2
Total hours = 2000 hrs
Therefore, Equivalent sun hours = 2000hrs/365days
= 5.5 hrs/day
3. Consideration for Results
The demand side has to size the load and calculate the daily
energy consumption in kWh.The configuration formanaging
the total load consumption for the entire site is shown in
table. which describes the total daily load demand for
residence, communal facilities, and commercial facilities.
The proposed area is a village as a sample selection, which is
located in central Myanmar at 19.00⁰ Latitude and 95.00⁰
Longitude nearly. Most of the people in this village mainly
depend on small patrol engine, batteries and some of people
are using candle lamp for lighting, phone charger and other
electricity appliances.
Load profile is mainly divided into three portions that are
residence, communal facilities and commercial facilities. In
residence, there are many kinds of household level such as a
high-income level, medium income level and low-income
level respectively. Electricity demand in low income level is
limited to lighting and TV, and the annual growth rate of
electricity consumption is small. In such Medium household
level, the annual growth rate of electricity consumption is
rapidly increasing. It is considered the facts as shown in
table 4.
It is calculated in the whole in which system battery size; no
of parallel batteries, battery capacity and data for PV array,

ABSTRACT
This paper is focused to develop solar system in rural area because the
electricity is the backbone of the country’s economy and only 40% is
electrified in Myanmar. In design load estimating and calculation the
components for the solar system and moreover environmental impact and
climate change is also a fact to consider in it. Myanmarhas high solarpotential,
photovoltaic (PV) system must be installed for most of the rural areas where
there is no national grid line. To develop off-grid PV system which support for
people to lift up their lives in rural areas. Mono-crystalline or single crystalline
silicon photovoltaic cells and lead acid batteries are goingtouseinthesystem.
The load estimation, PV sizing, inverter selection and battery sizing are
calculated mainly. Based on the results, the design consideration can be
absolutely applicable for the one village.

1. INTRODUCTION
The solar constant for the Earth is the irradiance received bytheEarthfromthe
sun at the top of the atmosphere, i.e., at AM 0, and is equal to 1367Wh/m2.After
passing through the atmosphere with a path length of AM 1, the irradiance is
reduced to approximately 1000Wh/m2, and hasamodifiedspectralcontentdue
to atmospheric absorption.
The irradiance for AM 1.5 is accepted as the standard
calibration spectrum for photovoltaic cells. Irradiation isthe
measure of energy density of sunlight and is measured in
kWh/m2. Since energy is power integrated over time,
irradiation is the integral of irradiance. Normally, the time
frame for integration is one day, which means during
daylight hours.
The average solar radiation in Myanmar is more than 5
kWh/m2/day during the dry season. It varies from 2.3 to 3.2
kWh/m2/day in the extreme north and south regions, while
the majority regions in Myanmar including the central area
have good solar radiation ranging from 3.6 to 5.2
kWh/m2/day in figure (2). Therefore, government and
private sector organizations have been promoting and
piloting solar PV systems for rural electrification[3].
The specific monthly solar radiation profile for the selected
village model is shown in Figure (1). The radiation is over
2000 Wh/m2. From this figure, the radiation is highest in
April (6.422 kWh/m2/day) and is lowest in August (4.532
kWh/m2/day).

2. Mathematical Review
The necessary equations are considered for designing
covered of solar system which is applied for a village. The
angle formed between the plane of the equator and a line
drawn from the center of the sun to the center of the earth is
called the solar declination, δ.Itvariesbetween theextremes
of ± 23.45°, and a simple sinusoidal relationship that
assumes a 365 day per year and which puts the spring
equinox on day n = 81 provides a very good approximation.
