Cost Analysis of Small Scale Solar and Wind Energy SystemsIJMER
Abstract: The recent dramatic increase in the use of
renewable energy systems leading towards competitive
markets within the various individual renewable energy
systems. The aim of this paper is to prove the hypothesis
i.e. in next few years, when the cost of the solar PV
modules come down below 1$ per Watt, small wind
turbines become more costlier because of the cost of
structures required to support the wind generator. And
also if the threat from the market is not addressed both
technically and commercially, small wind turbine
manufactures will lose the competition to solar PV module
manufactures in the near visible future. Objective of this
paper is to do cost analysis on the industry data and prove
hypothesis and to arrive at the cutoff point, where after the
generating energy from the wind is not economically
feasible. With this cost analysis, author here by alarm for
the small scale wind turbine manufactures to take
necessary measures to survive the competitive markets of
small scale renewable energy systems.
Keywords: Renewable energy, Solar PV, Wind Turbine, Curve Fitting, Cost analysis.

Construction of Solar Panel Laying System based on Genetic AlgorithmDr. Amarjeet Singh
Solar power generation is an important energy
resource in most countries. It plays an important role in
meeting energy demand, improving energy structure and
reducing environmental pollution. The main carrier of solar
power generation is solar panels, but the utilization efficiency
of most existing solar cells is low, which causes serious waste
of solar energy. In response to this phenomenon, we propose a
Solar Panel Laying System(SPLS) based on genetic
algorithm(GA) to construct solar panels, which solves four
problems: the determination of the number of battery
components, the layout of the panels, the selection of the
inverter and the connection of the inverter. In the SPLS ,we
introduce an improved genetic algorithm and multi-objective
optimization solution. Under the double premise that the total
amount of solar photovoltaic power generation is as large as
possible and the cost per unit of power generation is as small
as possible, the quantitative solution of the laying system is
realized.
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
hybrid system agrees reasonably with those published before.

This article describes the performance results of the first renewable microgrid of Chocó, Colombia, monitored over two years (2016-2017) adding an economic approach. A virtual platform is used to analyze, in real time, the microgrid power production, while a meteorological station measures the solar irradiance and the ambient temperature. The results indicated that the generation of AC PV energy was 21,817 kWh/year on 2016 and 23,301 kWh/year on 2017. The photovoltaic system’s average efficiency was 10.3 % on 2016 and 11.09 % on 2017. An economical analysis of the renewable microgrid is also presented using RETScreenTM software. The results show a net present value of $237,028 USD for an evaluation period of 25 years with annual energy savings of $4,622 USD. A calculation on greenhouse gas emissions show that 22.9 tCO2 per year are avoided when using the solar energy tech.

Modelling & Simulation of PV Module Connected with Three-Port DC ConverterDr. Amarjeet Singh
Of the world’s electricity is being generated through conventional sources of energy like coal and atomic energy. People have realized the dire effect of using these fuels, and the amount of CO2 being released into the environment. There has been a shift in emphasis towards cleaner ways of generating electricity in recent years. Solar energy is abundantly available and the cleanest renewable energy source available in the world and is ready to use for a variety of applications, such as the generation of electricity for residential, commercial, or industrial consumption and have become very competitive solutions. It can be seen that there is trend of solar photovoltaics (PV), which has seen rapid growth over the years. The increasing trend of adopting PV system allows consumers to be known as producers or “Prosumers”.
This report evaluates how solar PV can be used in combination with a battery bank along with three port converter to fulfill the requirement. Power production from PV cannot be consistent due to factors like the weather although The main benefits of solar power are that it can be easily installed cost of generation is low as there is no requirement for fuel and require very little maintenance Distributed maximum power point tracking (MPPT) and autonomous are achieved with the proposed configuration. The input-port of each TPC is connected to an independent PV energy source to achieve individual MPPT, and the output-ports of these TPCs are connected with load. Fully modular design is achieved by using Simulink/matlab.
A Comparative Study for Different Sizing of Solar PV System under Net Energy ...journalBEEI
Malaysia has moved forward by promoting the use of renewable energy such as solar PV to the public to reduce dependency on fossil fuel-based energy resources. Due to the concern on high electricity bill, Universiti Malaysia Perlis (UniMAP) is keen to install solar PV system as an initiative for energy saving program to its buildings. The objective of this paper is to technically and economically evaluate the different sizing of solar PV system for university buildings under the Net Energy Metering (NEM) scheme. The study involves gathering of solar energy resource information, daily load profile of the buildings, sizing PV array together with grid-connected inverters and the simulation of the designed system using PVsyst software. Based on the results obtained, the amount of solar energy generated and used by the load per year is between 5.10% and 20.20% from the total annual load demand. Almost all solar energy generated from the system will be self-consumed by the loads. In terms of profit gained, the university could reduce its electricity bill approximately between a quarter to one million ringgit per annum depending on the sizing capacity. Beneficially, the university could contribute to the environmental conservation by avoiding up to 2,000 tons of CO2 emission per year.
A Management of power flow for DC Microgrid with Solar and Wind Energy SourcesAsoka Technologies
Today there is a rapid proliferation of DC loads into the market and DC micro grid with renewable energy sources is emerging as a possible solution to meet growing energy demand. As different energy sources like solar, wind, fuel cell, and diesel generators can be integrated into the DC grid, Management of power flow among the sources is essential. In this paper, a control strategy for Management of power flow in DC micro grid with solar and wind energy sources is presented. As the regulation of voltage profile is important in a standalone system, a dedicated converter is to be employed for maintaining the DC link voltage. DC link voltage is regulated by the battery circuit while maximum power is extracted from Solar and Wind to feed the loads connected at the DC bus. A power flow algorithm is developed to control among three sources in the DC Microgrid. The algorithm is tested for various load conditions and for fluctuations in solar and wind power in MATLAB/SIMULINK environment.

comparative analysis of solar photovoltaic thermal (pvt) water and solarIJCMESJOURNAL
The present commercial photovoltaic solar cell (PV) converts solar energy into electricity with a relatively low efficiency less than 15%. More than 80% of the absorbed solar energy is dumped into the surroundings as heat after photovoltaic conversion. The electrical efficiency of photovoltaic system drops as its operating temperature rises and for this reason PV cooling is necessary. Therefore, stabilizing the temperature of photovoltaic modules at low level is highly desirable to improve the efficiency. Hybrid solar technology has the advantage of increasing the energy output per unit installed collector area. India as a tropical country is deemed to have a good potential of applying this technology. In this paper, solar PVT (Photovoltaic-Thermal) air and water collector hybrid systems were designed by using a poly crystalline silicon PV module as solar absorber and the comparative study was carried out. Air and water cooling of a commercial PV module configured as PVT air solar collector and PVT water solar collector by forced flow is studied. The energy and exergy performance of the PVT systems has been experimentally determined for various mass flow rates of fluids. The experimental result shows that the combined PVT system has got better performance than the simple PV and solar PVT water hybrid system has better efficiency than both. These systems are simple and suitable for building integration providing space heating depending on the season and for low temperature heating application.

Maximizing Output Power of a Solar Panel via Combination of Sun Tracking and ...ijtsrd
Energy is the basic needs for human comforts and day to day activities. Energy is the key factor for social and economic developments in today scenario. Now a day’s global warming is the main problem of developing counties, due to the nonstop combustion of fossil fuels all over the world, creating environmental hazards and reducing conventional energy sources. This scenario is contributing to the need to search for an new renewable source of energy, which is clean and available in excess. Due to the huge impetus in the government policies on the development of solar energy, it is acting as a main alternative renewable energy source. The solar energy is popular due to easy maintenance, cleanliness, sustainability, and zero noise characteristics. Therefore, Photo Voltaic module supplying loads with and without Maximum Power Point Technique MPPT is applied in the current studies to find the best results. Since the Photovoltaic array output is known to be affected by radiation of sun and temperature, which makes is compulsory to find out an effective method to draw out maximum power from Photo Voltaic cell modules. In my work, Perturb and Observe PandO algorithm is selected because of its easy implementation Solar energy is the clean and eternal source of energy till the end of the world. In this paper main focus is how to improve the efficiency of solar based power generation .Solar energy is variable depends upon the time and the atmospheric condition and hence output of the solar cell is directly proportional to the insulation level and inversely proportional to cell temperature and also the cell never operates at maximum power.

Abstract
Present day guided weapon systems, especially tactical class missiles use RF seeker, for target tracking towards terminal engagement. The seeker system including its antenna assembly will be onboard the missile. Due to the missile trajectory corrections, the seeker antenna pointing to the target may get disturbed resulting in track loss. To avoid this track loss, it becomes necessary to stabilize the antenna system in two planes. The fundamental role of stabilization loop in seeker application is to precisely follow the angular rate of the target. In order to achieve this requirement, it is essential to highly isolate the gimbaled antenna from the missile body motion due to the maneuvering of target or low frequency vibration during flight. However, the isolation ratio and stability margin of stabilization loop adopting the gimbaled platform with both low stiffness and heavy inertia are limited by mechanical characteristic such as low resonance frequency and its high magnitude. The selection of proper feedback sensors, modeling of the total system are key features of this project. In the end, the performance and the stability of designed stabilization loop are demonstrated using simulation in both frequency and time domain. The Hardware for the system is under realization by the Industry. The whole scheme is simulated in MATLAB off-line for this project.
Keywords: Missile, RF seeker, Track loss, Stabilization loop, Angular Rate Command, Bore-Sight Error, Maneuvering and Gimbaled Platform.

Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

I. Introduction
Basically from solar cell & wind mill gives the DC voltage output store in the battery & through
inverter circuit it gives 230v AC output which can use for building surrounding lights & stair case lights & as
well as main load.
Under current acute power shortage scenario with increasing cost of natural gas, coal and other power
generator turbine fuel, there is a very urgent and great need of finding alternate source of energy to generate
electricity. Of all the renewable energy sources, solar energy received the greatest attention in the decade of the
1970’s and has been the rub of much emotion and pleasure. Many regarded it is as the solution for reducing the
use of fossil and nuclear fuels and for a linear environment solar energy as a result has been the object of
inflated. Overly optimistic predictions ranging from largely supplementing to eventually replacing all the
current means of production of both electric power and thermal energy requirements. Solar energy, in sheer six
does have the potential to supply voltage energy needs Electric, thermal chemical even transportation fuels .it is
however, very diffuse cyclic and often undependable. Although solar energy may be used in many markets such
as in active and passive space heating and cooling industrial process heating ,desalination and in electric
generation.After investments by federal and agencies amounting to several hundred million dollars in the 1970’s
and all these technologies, only one is in commercial use today. Namely flat plate collectors for water heating
.All other remain in various stages of research and development .It now appears that solar electric systems are
not expected to make engineering and economic sense as central generating plants of hundreds of mega watts
capacities in the foreseeable future [1].
Solar panel & wind mill are the main source. Basically from solar cell & wind mill gives the DC
voltage output store in the battery & through inverter circuit it gives 230v AC output which can use for building
surrounding lights & stair case lights as well as main load.The system was designed and implemented with the
following goals to be completely different from traditional electricity labs and to be fresh and interesting.To be
intimately related to real world industrial power issues such as power quality. To show a complex, interrelated
system that is closer to the “real world” than the usual simple systems covered in educational labs.
To motivate learning by introducing such elements as environmental and economic concerns of
practical interest to the students. This paper describes a new PSoC microcontroller based PV (photovoltaic)
system. Because the energy from the sun, fluctuates with climate conditions, the impedance of the PV system
must be adjusted to match the change in lighting condition. To do this, we employ a PSoC microcontroller
which can handle both analog and digital circuits, to reduce the need for additional circuit elements. The PSoC
controller is used as a programmable Maximum Power Point Tracking (MPPT) controller.
The intermittent nature of solar and wind power can be effectively mitigated by using a solar and wind
hybrid system. Energy storage on-site (batteries) ensures that power is available when the sun isn't shining or the
wind isn't blowing. Pairing solar and wind collection systems at one site can provide diversity protection against
the variable natures of both energy sources [10].

II. Literature Review
The literature in the subject areas of this is very extensive. An excellent textbook for instructional use
is Wind and Solar Power Systems by Patel (1999) that covers the specific issues in this project in a style
appropriate for Industrial Technology students. Sabin (1999) and coworkers have summarized the various
standards and benchmarks used in large-scale power quality, and Koval (1999) and coworkers have presented
similar finding for rural (small-scale) power quality problems. Taylor (1987) is responsible for some of the early
practical work on power quality measurements in wind generation [1].
Kariniotakis and Stavrakakis (1995) have written extensively on simulation problems in wind
generator and power grid interactions. Finally, many papers have been written on the electronics regulation/
control aspects of the problem including a recent study by Neris and co-workers (1999) proposing an IGBT
(Integrated-Base-Bipolar-Transistor) based regulator [3].
The novel approach of MPPT control algorithms developed from various photovoltaic technology [6].
Barbosa (1998) and coworkers have described the use of PWM (pulsewidth- modulation) control schemes to
power quality control. Numerous studies have appeared describing the impact of power quality problems caused
by PV systems from early work by McNeil (1983) and coworkers in to more recent work by Oliva (1988) and
coworkers and most recently by Chowdhury (1999).[8]
Many articles have appeared on the impact of new electronics technologies on power quality
management, for example Poisson (1999) and coworkers have described the impact of DSP chips on the
problem [10].
The extensive literature on power quality aspects of wind generation includes work by Demoulias and
Dokopoulos (1996) on transient power measurement and by Thiringer (1996) on harmonic contamination
measurement issues [10]. Amit Kumar; Dr. Yunfei Liu; Dr. Manu Sood; Tanvir Singh; S Singh“Sustainability
in Wireless Mobile Communication Networks through AlternativeEnergy Resources” IJCST Vol. 1, Iss ue 2,
December 2010.
Numerous technologies hold promise for harnessing and utilizing the sun’s energy. They include:
agricultural and architectural technologies, solar lighting, solar thermal, HVAC, solar cookers, electricity
generation, solar to petroleum, transportation, and satellites to mention a few.A number of well-known large
corporations have launched initiatives to generate their own energy for a variety of reasons, such as reducing
energy price volatility, increasing security of supply, decreasing costs or meeting carbon objectives. Example -
companies with their own renewable energy generation include IKEA, Google, Toyota, Toshiba, Hertz, FedEx,
AT&T, BMW, Renault, VW, Audi and PepsiCo. VW, for example, is investing €1b in offshore wind projects to
meet renewable energy objectives and provide a natural hedge against volatile energy prices. That said, a third
of respondents expect to meet a greater share of their energy needs through self-generation over the next five
years [12].
Fig 2.1. Power-voltage characteristics of PV [1].
Now a days the big problem of electricity. There is no alternate source available in emergency. Thus
we are trying to reduce the problems of electric energy by using the natu ral source like solar power & wind
power.
Figure 2.1 shows the P-V characteristics of a PV cell. The available electric power from the PV cell
varies depending on the P-V curve, which is determined by the characteristics of the PV cell. Since the P-V
curve is a convex curve, a maximum power point (MAXP) exists, which changes with the intensity of solar
irradiation. Therefore, in order to maintain the output power of the PV cell at MAXP even while the solar
irradiation is changing, MPPT control is needed [1].
In order to obtain the maximum power from the PV cell as shown in Fig. 1, we need to find and control
the maximum power point voltage (VMPP) which may vary depending on the sunlight conditions. To obtain the
maximum power, we apply the constant voltage method to find MPPV from the open-circuit voltage (Voc).

III. Problem Statement
The proposed system is to reduce the problems of electric energy by using the natural source like solar
energy. The solar cell give the DC voltage output to store in the battery & through inverter circuit , it gives
230V AC output which can use for building surrounding lights, stair case lights as well as main load. The actual
proposed system designed by using solar installation.
This proposed system uses PSOC microcontroller based (photovoltaic) because the energy from the sun
fluctuates with climate conditions; the impedance of the PV system must be adjusted to match the change in
climate condition. In this system, PSOC microcontroller can handle both analog and digital circuits, to reduce
the need for additional circuit elements. PSOC is an application related review of programmable array systems
& the system-on-chip.
IV. Working Principal
AS people are much concerned with the fossil fuel exhaustion and the environmental problems caused
by the conventional power generation, renewable energy sources and among them photovoltaic panels and
wind-generators are now widely used. In this we are using solar panel & wind mill are the main source.
Basically from solar cell & wind mill gives the DC voltage output store in the battery & through inverter
circuit it gives 230v AC output which can use for building surrounding lights & stair case lights & as well as
main load.
4.1Photovoltaic technology
Photovoltaic is the field of technology and research related to the devices which directly convert
sunlight into electricity. The solar cell is the elementary building block of the photovoltaic technology. Solar
cells are made of semiconductor materials, such as silicon. One of the properties of semiconductors that makes
them most useful is that their conductivity may easily be modified by introducing impurities into their crystal
lattice.
The intermittent nature of solar or wind power can be effectively mitigated by using a solar or wind
system. Energy storage on-site (batteries) ensures that power is available when the sun isn't shining or the wind
isn't blowing. Pairing solar and wind collection systems at one site can provide diversity protection against the
variable natures of both energy sources.

4.2.Wind energy-
Wind power is the conversion of wind energy into a useful form of energy. All renewable energy
(except tidal and geothermal power), ultimately comes from the sun . About one or 2 percent of this energy is
converted to wind energy (which is about 50-100 times more than the energy converted to biomass by all plants
on earth.

4.3.Battery
An electrical battery is one or more electrochemical cells that convert stored chemical energy into
electrica energy. Here are two types of batteries: primary batteries
which are designed to be used once and discarded when they are exhausted, and secondary batteries
which are designed to be recharged and used multiple times.
The CY8CKIT-030 PSoC 3 Development Kit is based on the PSoC 3 family of devices. PSoC 3 is a
Programmable System-on-Chip™ platform for 8- and 16-bit applications. It combines precision analog and
digital logic with a high-performance CPU.
4.4.PSoC Creator-
“PSoC” is an application related review of programmable array systems, the system-on-chip. Cypress's
PSoC Creator software is a state-of-the-art, easy-to-use integrated development environment (IDE) that
introduces a hardware and software design environment based on classic schematic entry and revolutionary
embedded design.
4.5.LCD display-
A liquid crystal display (LCD) is a thin, flat electronic visual display that uses the light modulating
properties of liquid crystals (LCs). LCs does not emit light directly.
4.6. LDR-
The main purpose of a light dependent resistor is to change the brightness of a light in different weather
conditions. This can easily be explained with the use of a watch. It is the light dependent resistor that allows the
watch to know when it has gotten dark, and change the emissions level of the light at that time.
4.7.Relay driver-
The eight NPN Darlington connected transistors in this family of arrays are ideally suited for
interfacing between low logic level digital circuitry (such as TTL, CMOS or PMOS/NMOS) and the higher
current/voltage requirements of lamps, relays, printer hammers or other similar loads for a broad range of
computer, industrial, and consumer applications. While the proposed analysis can be used to differentiate
between competing energy storage technologies and determine the maximum energy storage requirement, the
determination of the actual energy storage technology should be based on a life cycle costing analysis.

VI. Conclusion
In this case we are following all component & aspects of generating energy from solar cell easy,
convenient & in user friendly way for non technical person, by using latest development of electrical and
electronics. It is useful for providing grid quality, reliable power in rural areas where the line voltage is low and
insufficient to connected load. In other places, other power sources could be used. For example hybrid
combinations of wind power, solar power, geothermal power, hydroelectric power, tidal power, biomass
generated power, power from incineration of solid wastes, and many other technologies could be considered
depending on local interests and resources. PSoC is an industrial tool, aiming shorter design to market cycle. It
targets professional applications and university projects with limited budget, as well. The key elements of this
test bed concept presented in this paper are two or more renewable power sources connected to a power grid
with complex electrical interactions. The Govt. of India is planning to electrify 18,000 villages by year 2012
through renewable energy systems especially by solar PV systems. . The various MPPT (Maximum Power Point
Tracking) methods are also applicable for control mechanism
