Analysis Of Solar PV Power Generation

The PV module has been designed by considering the irradiance, temperature and number of PV cells connected in series and parallel. Figure 5.1 shows the simulink model of solar system. Here only function file used to show the solar system, the program code is given in the appendix. Here we are using a battery. The system is generated 240volt and current is 2.9 A.

The simulation study of the complete system is carried out by using MATLAB/SIMULINK. For this simulation, four PV module in a series connection mode is considered. Each PV module consists of three submodules. A multiwinding flyback converter is connected across each PV module. Fig. 7(a) shows the P-V charactristc cunve of the PV array (with bypass diode) without using the integrated converter. The figure shows multiple power peaks with maximum power nearly 500W. The shading pattern of the PV array is presented in Table-1. Fig. 7(b) shows the characteristic curve by integrating the converter across each PV module. The P-V characteristic curve exhibits a single peak point. The peak power is nearly 670W. As compared to conventional PV system more than 150W power can be extracted from the PV system. Each submodule of the PV module is subjected different solar insolation. Fig. 8(a ) shows the current of submodule of PV module-1. In this figure, submodule-3 generates less power as

Only 30 to 40 percent of the incident solar irradiation converts into electrical energy by solar panel. For improve the efficiency of the solar panel Maximum power point tracking technique is used, which track the maximum power of solar panel.

In recent years, Energy comes from natural resources such as sunlight, wind, rain, tides and geothermal heat. These resources are renewable. Therefore, for all practical purposes, these resources can be considered to be unlimited, unlike dwindling conventional fossil fuels. The renewable energy sources are known to be much cleaner and produce energy without the harmful effects of pollution unlike their conventional counterparts. Solar energy is converted into electrical energy and the electrical power generation in PV systems is highly affected by the temperature and the insolation level which makes it impractical to directly connect them to the load without any storage devices or utility grid interface. The PV systems focused on the minimization of the installation costs and the maximization of the energy capture and conversion efficiency. In order to maximize the conversion efficiency, the PV system should be operated at its maximum power point (MPP). This power is supplied to the load using parallel power processing topology to reduce the amount of power processed through the converter and, hence, decrease the converter size and increase the efficiency by means of direct energy transfer (DET).The concept of the PPP topology is shown in Figure.

Solar cells technology, as a clean power source of new generation, has been great developed in the past 35 years. The market needed for this for the solar cells technology is also greatly increased while module cost is decreased.

Sun oriented power has demonstrated high potential as a source of energy as the figure 1 beneath shows. Right now, a board can harness around 16% of the energy that falls on the surface of the board. The pv boards are in this way unsustainable considering there is more than 84% wastage (Sokona, Pichs-Madruga, and Edenhofer, 2012). But, the energy created utilizing the boards are adequate to help industries.The researcher’s put the production projection high when the panels will have the ability to harness over 80%

The growing concern about the impact of CO2 and the anxiety on the effect of using fossil fuels based power generation technology on the environment, in recent years, has made the researchers to focusing on the renewable energy based clean power generation techniques to secure the environment from carbon effect. Among the development of renewable energy based power generation techniques, the solar power generation has a major role in clean power generation. The sunlight is free of cost and everlasting energy sources, but the drawback of this method is that generation of electricity is only possible during the sunshine. In PV system, the DC-DC power converters are used to change the output voltage from one level to another level [25-27]. Typically, the DC-DC converter is connected between the panel and the load, sequentially to extract the available power from the panel using tracking methods. In this work, Boost converters and Super lift boost converters [1] are used to extract the maximum power from the panel and two converters diagram is shown in Figure 1a and Figure 1b respectively.

Photovoltaic array is a photovoltaic system which is a interconnection PV modules. Sometimes the power generated by single PV module does not meet the requirements of commercial usage.so PV modules are connected to form PV array. To get high or increased voltage we connect the PV modules in series and to get high or increased current. We connected PV modules in parallel. To convert DC (Direct current) power to AC (Alternating Current) which runs motors, loads etc. an inverter is used.

Now a day’s people are more concerned about the application of the renewable energy source, like wind, tidal, biomass, ocean and solar radiation (photovoltaic) because of the raising oil prices, fossil fuel deficit, global warming and negative impact of environment. Among all the renewable energy sources the energy through photovoltaic (PV) can be most

THIS IS TO CERTIFY THAT THE PROJECT ENTITLED WITH “SOLAR TRACKING SYSTEM AND HYBRID POWER GENERATION” HAS BEEN COMPLETED BY ANKUR BUSA, ABHISHEK SINGH, MUGDHA JAIN AND MEGHA PATEL OF UNDER MY GUIDANCE IN FULFILMENT OF SEMESTER-VII OF BACHELOR OF ENGINEERING IN ELECTRONICS AND TELECOMMUNICATION ENGINEERING DEPARTMENT DURING THE ACADEMIC YEAR 2016-2017.

The converter consists of linear circuit elements L, C, R as well as non-linear circuit elements, which are power electronic switches. The converter as such is not a linear system. This metaheuristic optimized method, control the switching signals from the power electronic converter circuits such as boost converter, inverter, etc. Boost converters are a kind of high- frequency converter, which convert unregulated DC power to synchronized DC power. A PV system can produce maximum possible power if it is operated at MPP. In view of achieving this maximum PV power, an MPPT is employed between the PV panel and load. This paper provides a review and comparative study of the optimized MPPT approaches [2]. The photovoltaic module’s maximum

In Figure.4, it can be analyzed that the system with MPPT control using GA brings the load power to the desired value of 480 W in 152 ms, whereas the system without MPPT reaches the desired output power of 310 W at 120 ms. Without any MPPT algorithm, the PV array will provide a power of about 310 W, which is an inefficient output under such a climatic condition.

ABSTRACT: This Project deals with a fully parallel Embedded Z-source inverter to control the three phase induction motor. Z-Source inverter is a single-stage converter which performs both buck-boost energy conversions using the LC impedance network. The further advancement in the Z-Source inverter is the partially parallel Embedded Z-Source inverter that can produce same gain as Z-Source inverter. Energy from the solar cell is taken as input to the EZ-source inverter. The ripple content of the solar cell output voltage is reduced using Parallel EZ-Source (PEZS) inverter. In order to overcome the drawbacks of PPEZS, Fully parallel EZ-(FPEZS) Source inverter is proposed. The proposed inverters provide high boost voltage inversion ability, a lower voltage stress across the active switching devices, a continuous input current and a reduced voltage stress on the capacitors. In addition, they can suppress the startup inrush current, which otherwise might destroy the devices. The proposed system reduces six switch three phase inverter to four switch three phase inverter. This makes system compact which reduces cost and switching losses, line harmonics, improves power factor, reliability

Abstract: The current energy situation with fossil fuels as the main source of the world’s energy has two main flaws: fossil fuels contribute to global warming via the greenhouse effect and they are limited in the quantity that remains. Solar power solves both of these problems and can be captured by utilizing photovoltaic cells. However, photovoltaic cells have their own drawbacks due to their high costs of installation and maintenance.
