Partial Shade Detection for PV Solar Panels via CUSUM AlgorithmUzair Akbar
The quality of power supply from photovoltaic solar panels is very sensitive to shading effects of single or multiple cells. The energy yield of a partially shaded photovoltaic system is much lower than we could assume from the mean solar irradiance. Some of the power loss due to partial shading can however be reduced by removing any shading objects that might appear when shade is detected on the solar panels.
The present work studies a method for real-time detection of partial shade on solar panels by monitoring the output power. We use the sequential change point detection algorithm CUmulative SUM (CUSUM) to detect any sudden deviation in the output power time series, and to raise an alarm for the user.
The experimental results on the output power of real photovoltaic panels show that our proposed approach can detect partial shading with low delay and high accuracy.
The electric power supplied by a photovoltaic power generation system depends on the solar radiation and temperature. Designing efficient PV systems heavily emphasizes to track the maximum power operating point.
This work develops a three-point weight comparison method that avoids the oscillation problem of the perturbation and observation algorithm which is often employed to track the maximum power point. Furthermore, a low cost control unit is developed, based on a single chip to adjust the output voltage of the solar cell array.
This project proposes a simplified PV module simulator with MPPT. The PV model is designed in Matlab/Simulink based on various mathematical equations. This paper explains the use of MPPT technique in a photovoltaic system. The MPPT is implemented by incremental conductance or perturbation and observation methods. The overall system is designed, developed and validated by using MATLAB/SIMULINK

In this paper, the comparative analysis of two maximum power point tracking (MPPT) algorithms namely Perturb and Observe (P&O) and Incremental conductance (InC) is presented for the Photo-Voltaic (PV) power generation system. The mathematical model of the PV array is developed and transformed into MATLAB/Simulink environment. This model is used throughout the paper to simulate the PV source characteristics identical to that of a 20 Wp PV panel. The MPPT algorithms generate proper duty ratio for interfacing dc-dc boost converter driving resistive load. The performances of these algorithms are evaluated at gradual and rapidly changing weather conditions where it is observed that InC method tracks the rapidly changing insolation level at a faster rate as compared to P&O. Depending upon the prevailing environmental conditions the MPPT algorithms finds a unique operating point to track the maximum available power. The algorithms find a fixed duty ratio by comparing the previous power, voltage and current thereby optimizing the power output of the panel. The main objective is to compare the tracking capability and stability of the algorithms under different environmental situations on par with other real world tests.

Making model of dual axis solar tracking with Maximum Power Point Trackingijsrd.com
Now a days solar harvesting is more popular. As the popularity become higher the material quality and solar tracking methods are more improved. There are several factors affecting the solar system. Major influence on solar cell, intensity of source radiation and storage techniques The materials used in solar cell manufacturing limit the efficiency of solar cell. This makes it particularly difficult to make considerable improvements in the performance of the cell, and hence restricts the efficiency of the overall collection process. Therefore, the most attainable maximum power point tracking method of improving the performance of solar power collection is to increase the mean intensity of radiation received from the source used. The purposed of tracking system controls elevation and orientation angles of solar panels such that the panels always maintain perpendicular to the sunlight. The measured variables of our automatic system were compared with those of a fixed angle PV system. As a result of the experiment, the voltage generated by the proposed tracking system has an overall of about 28.11% more than the fixed angle PV system. There are three major approaches for maximizing power extraction in medium and large scale systems. They are sun tracking, maximum power point (MPP) tracking or both.

Fuzzy Sliding Mode Control for Photovoltaic SystemIJPEDS-IAES
In this study, a fuzzy sliding mode control (FSMC) based maximum power point tracking strategy has been applied for photovoltaic (PV) system. The key idea of the proposed technique is to combine the performances of the fuzzy logic and the sliding mode control in order to improve the generated power for a given set of climatic conditions. Different from traditional sliding mode control, the developed FSMC integrates two parts. The first part uses a fuzzy logic controller with two inputs and 25 rules as an equivalent controller while the second part is designed for an online adjusting of the switching controller’s gain using a fuzzy tuner with one input and one output. Simulation results showed the effectiveness of the proposed approach achieving maximum power point. The fuzzy sliding mode (FSM) controller takes less time to track the maximum power point, reduced the oscillation around the operating point and also removed the chattering phenomena that could lead to decrease the efficiency of the photovoltaic system.
An Experimental Study of P&O MPPT Control for Photovoltaic SystemsIJPEDS-IAES
Tracking the maximum power point plays an important role for the optimization of the solar energy. The objective here is to study experimentally optimizing photovoltaic (PV) systems connected to a DC-DC converter (Boost) and a resistive load. For this, tests were conducted to determine the law of open loop control (power versus the duty cycle) for different solar irradiance values and load with an approximately constant cell temperature. The obtained results showed that the power passes through a maximum point. In order to extract the maximum power, for different values of solar irradiance and load, an MPPT control "Perturb and Observe" P & O has been implemented on a DSPACE 1104. The experimental results showed the performance of the method suggested.

Modeling and Simulation of Solar Photovoltaic Systemijtsrd
Solar energy is a vital untapped resource in a tropical country like ours. The main hindrance for the penetration and reach of solar PV systems is their low efficiency and high capital cost. The efficiency of solar PV is very low. In order to increase the efficiency, Maximum Power Point Tracking (MPPT) techniques are to be undertaken to match the source and load property. These techniques are employed in PV systems to make full utilization of PV array output power. Recently, many MPPT algorithms of PV system have been proposed which depends on solar irradiation and temperature, but perturb and observe (P&O) and Incremental conductance algorithms are basic and most widely used. This project firstly introduces a Mat lab Simulink of photovoltaic array. To achieve the maximum power point tracking the Incremental Conductance method and perturb and observed (P&O) method are used. These two algorithms are employed with PV model along with converter in Mat lab Simulink. Three different converter boost, buck boost and cuk converter are design according to requirement and used.

Reducing Silicon Real Estate and Switching Activity Using Low Power Test Patt...ijsrd.com
Power dissipation is a challenging problem for today's system-on-chip design and test. This paper presents a novel architecture which generates the test patterns with reduced switching activities; it has the advantage of low test power and low hardware overhead. The proposed LP-TPG (test pattern generator) structure consists of modified low power linear feedback shift register (LP-LFSR), m-bit counter, gray counter, NOR-gate structure and XOR-array. The seed generated from LP-LFSR is EXCLUSIVE-OR ed with the data generated from gray code generator. The XOR result of the sequence is single input changing (SIC) sequence, in turn reduces the switching activity and so power dissipation will be very less. The proposed architecture is simulated using Modelsim and synthesized using Xilinx ISE9.2.The Xilinx chip scope tool will be used to test the logic running on FPGA.
Defending Reactive Jammers in WSN using a Trigger Identification Service.ijsrd.com
In the last decade, the greatest threat to the wireless sensor network has been Reactive Jamming Attack because it is difficult to be disclosed and defend as well as due to its mass destruction to legitimate sensor communications. As discussed above about the Reactive Jammers Nodes, a new scheme to deactivate them efficiently is by identifying all trigger nodes, where transmissions invoke the jammer nodes, which has been proposed and developed. Due to this identification mechanism, many existing reactive jamming defending schemes can be benefited. This Trigger Identification can also work as an application layer .In this paper, on one side we provide the several optimization problems to provide complete trigger identification service framework for unreliable wireless sensor networks and on the other side we also provide an improved algorithm with regard to two sophisticated jamming models, in order to enhance its robustness for various network scenarios.
DESIGN OF FIXTURE OF CONNECTING ROD FOR BORING OPERATIONijsrd.com
Connecting rod is very important part of engine. It should be accurately machined with the acceptable tolerance. Also the fluctuations of dimensions in work-piece to work piece should be minimum so that it will be easier to assemble in engine. But it has been observed that the required dimensions for the bolt diameter and smaller end diameter for the connecting rod are not continuously achievable by using the existing fixture. The diameters required of the bolts and the smaller end of the said connecting rod are 10±0.05 mm and 24±0.01 mm respectively The aim of this project is to design and development of a new fixture for machining (Boring) operation using designing software's i.e. Pro E and analysis using ANSYS ,which can eliminate the said problems.

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.

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.

Abstract— The configuration of a most extreme force point
following (MPPT) controller for a sun based photovoltaic
force framework is proposed using a help converter
topology utilizing PSO calculation. Sunlight based board
voltage and current are consistently checked by a shut circle
focused around PSO microcontroller control framework, and
the obligation cycle of the help converter persistently
changed in accordance with concentrate greatest force.
Framework testing affirms crest force following under
changing lighting conditions. Under particular conditions,
efficiencies in overabundance of 96% are demonstrated to
be conceivable.
Key words: PSO, Maximum Power Point Tracking,
Photovoltaic Generator, Transparent Conductive Oxide
I. INTRODUCTION
Sunlight based force is an option engineering that will
assuredly lead us far from our petroleum subordinate vitality
sources. The real issue with sunlight based board innovation
is that the efficiencies for sun based force frameworks are
still poor and the expenses for every kilo-watt-hour (kwh)
are definitely not focused, much of the time, to contend with
petroleum vitality sources. Our objective is to plan a
Maximum Power Point Tracker (MPPT), a particular sort of
charge controller that will use the sun oriented board to its
most extreme potential. The MPPT screens the yield voltage
and present from the sun based board and decides the
working point that will convey that greatest measure of
force accessible to the batteries. Utilizing PSO method
MPPT can precisely track the continually changing working
point where the force is busy's greatest, and afterward the
productivity of the sun oriented cell can likewise be
expanded. The expense profit for sunlight based force
frameworks is so low there is no option be broadly utilized
for fueling homes, organizations, or even individual items.
Then again, the profit of using sun powered power in space
far exceeds the expense to execute them. Sun powered force
framework is less expensive than the expense to send
transmission lines from the force matrix. On the other hand,
PV frameworks further improve the rate at which the
electron sent into the conduction band through the procedure
of doping .Solar force is an astounding innovation as in it
changes over daylight into power through the semiconductor
material alone. Over the long haul, more up to date
producing procedures and plans will demonstrate these sun
powered boards more proficient and less excessive in future
years. A sun based board's yield shifts relying upon certain
surrounding climate conditions, for example, temperature,
enlightenment, how clear the sky is, on et cetera. Our
current workload is to plan a gadget that will extricate the
most extreme sum.
II. VOLTAGE-CURRENT (V-I) CHARACTERISTIC
Extracting the maximum amount of power from the solar
panel is difficult due to the nonlinearity of the Voltage-
Current (V-I) characteristic. Figure 1.1 shows the V-I
characteristic for Solar Corp’s 379 Solar.
Fig. 1.1: Characteristic of Solar Corp 379 Panel
The blue line in Figure 1.1 is the actual V-I
characteristic and the pink line corresponds to the power as
a function of the voltage (P = I*V).To get the maximum
power from the solar panel, the solar panel must always be
operated at or very near the point where the power curve is
at a maximum, its peak point. However, this operating
point will constantly change due to the constantly changing
ambient conditions. Irradiance is a characteristic that deals
with the amount of sun energy reaching the ground. The
irradiance reaching the earth significantly depend on where the
panel is located geographically, the angle of the sun, and the
amount of haze or cloud cover preventing all of the suns
energy from reaching the ground. Silicon Semiconductor
solar panel will decrease from 1700 cm2/volt-sec at 27o
C to
440 cm2
/volt-sec at 227o
C.where the hole mobility will
decrease from 600 cm2
/volt-sec at 27o
C to 200 cm2
/volt-sec
at 227o
C[4]. Temperature also causes the band gap energy
of the semiconductor material to increase. Insolation levels
measure the amount of energy in watt-hours for a square
meter over a single day in Kwh/m2
/day. Insolation level units
are not always stated, and can be seen as a ratio.

Ten of our 50W solar cells would generate
500W[3]. This would yield a maximum of 20.8A, very
comparable to other controller’s ratings. The table below
shows how big our batteries must be in amp hours, to
provide a 100W light bulb with power.

Table 1.3 is calculated using the following formula
Calculating the derivative gives more insight into
the effect of the quantization noise in power. The derivative
is calculated as follows.
The difference in the two power samples is 32
rather than the quantization of 1 from the voltage and
current samples. Calculating the derivative gives more
insight into the effect of the quantization noise in power.
The derivative is calculated as follows.
This means that one bit change in current and voltage
will create a derivative of 32 / e in
register value equals 0.078 watts / duty cycle. This will get
worse as the voltage or current moves up towards their
maximum value.
To test this quantization on our system, a steady duty
cycle is applied to the input of the system while measured the
changing voltage and current samples.
This setup is shown in Fig. 1.4
Fig. 1.4: Test Setup to Measure Quantization and Noise
The resulting voltage and current quantization
noise is shown in Figures 1.5 and 1.6. Note the values are in
10 bit register values

V. EXPERIMENTAL EVALUATION
So as to research the precision and execution of the
proposed technique, a photovoltaic (PV) framework
incorporates: one OFFC silicon sun powered board, a
DC/DC converter, a battery and control framework (PSO
MPP tracker and PID controller) are viewed as and recreated
in MATLAB/SIMULINK programming. Which
incorporates the PV module, the buck-help converter
(Rashid, 2004) and the MPPT calculation The buck –
support dc/dc converter is used because of a few reasons, in
particular it displays better attributes with deference than the
execution of PV cluster's MPP and it takes after the MPP at
all times, paying little heed to the sunlight based insolation,
the show temperature, and the associated burden. The PV
module current and voltage are encouraged to the converter
and the MPPT controller all the whi.

VI. CONCLUSION
To finish this undertaking in a compelling way an
exhaustive understanding of sun powered innovation
and The most doable application for sun oriented force
is for remote areas obliging little amounts of force to
run lighting, pumps, and other low power applications.
Just uniting a sun powered board to a battery or a heap
can further decline the accessible productivity. Sunlight
based force frameworks profit from a MPPT gadget
keeping in mind the end goal to concentrate the greatest
accessible force from the sun powered boards in the
framework. By observing the voltage and current yield
of the sun oriented board, the MPPT tracks the
continually changing working indicate in place draw the
most extreme measure of force accessible amid all
times of the day. To meet this principle outline
necessity, numerous segments and working conditions
were chosen focused around a proficiency examination
that was performed keeping in mind the end goal to
minimize the force misfortune through the hardware. A
careful force misfortune examination turned out to be
more prominent than 96% effective. A circuit that
would screen the sun based board's energy yield and
alter the working conditions focused around a control
framework so as to expand the force yield was
effectively outlined. An exceptional flow sensing
thought was executed that minimized the force
misfortune contrasted with different plans inquired
about.
