Power Plane Analysis Of Phot Ovoltaic Module For Maximum Power Point

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

International Energy Agency then after IEA defines renewable energy as energy derived from natural processes e.g. wind and sunlight. Moreover, renewable energy is replenished at a faster rate than consumed such as solar, wind, geothermal, hydro and some forms of biomass.

Renewable energy is energy generated from natural sources such as sunlight, wind, rain, tides and geothermal heat. Nowadays, developed countries such as U.S.A, Australia and other more countries are giving preference to renewable energy because it helps us to reduce the pollution problem. Canada is also showing their interest in the renewable energy sources and it has dramatic growth in renewable energy sector.

Renewable energy is derived from sources that are naturally replenish-able and supply of energy from these sources is infinite. The main purposes served by using renewable energy are many such as generation of power, transport fuel production, and for heating of houses and other living places. Except the naturally occurring main difference of supply source between renewable and non-renewable energy, there are several industry related differences as well. Usability of renewable energy, level of Greenhouse Gas (GHG) emissions, cost of generating energy, and the phase from renewable energy production is passing through, all these industry related aspects for both renewable and non-renewable energy are different.

The demand for electricity it is increasing in recent years, mainly because the world population is also increasing. The necessity for power generations is a constantly subject across the globe and is from that point that the concept of renewable energy emerge and become an important subject.

Using renewable sources are becoming an alternative of fossil fuel because of their infinite supply, low carbon emission, price stability in the energy market and economic benefits. Examples of renewable sources include solar photovoltaic (PV), wind,

“ The Energy Pay Back Time is defined by EPBT = Einput/Esaved, where Einput is the energy input during the module life cycle (which includes the energy required for manufacturing, installation, energy use during operation, and energy needed for decommissioning) and Esaved the annual energy savings due to electricity generated by the PV module. EPBT depends on a number of factors: cell technology, type of encapsulation, frame and array support, module size & efficiency, PV system application type (autonomous or grid-connected) and, finally, PV system performance as determined by irradiation and the performance ratio. EPBT is also affected by factors that do not directly relate to the characteristics of the PV power system itself: conversion efficiency of the electricity supply system and energy requirements of materials like glass, aluminum etc. ”

India has been consistently a power shortage nation with demand and supply gap of 12% of the total energy demand. With its proximity to the equator, India has a potential of generating 1900 billion units of solar power annually. Solar

India has a installed total power generation capacity of 250256.98 MW as on February, 2014(CEA 2014) stands as third largest producer and consumer of electricity, to fulfill its exponential growth in power requirement it requires a generation capacity of 440GW to be added by 2017. India needs to shift its focus from building base-load plants which are dominated currently to a more balanced mix of base loads and peak production plants, the alternative as solar or other renewable energies is much required as

Solar power is attractive because it is abundant and offers a solution to fossil fuel emissions and global climate change. Earth receives solar energy at the rate of approximately 1,73,000 TW . This enormously exceeds both the current annual global energy consumption rate of about 15 TW and any conceivable requirement in the future. India is both densely populated and has high solar insolation, providing an ideal combination for solar power in India.

The Indian solar PV market has seen significant growth with the installed solar PV capacity, rising from 40 MW to more than 3,000 MW in the last four years. It is also expected that the distributed generation (rooftop Solar PV) at the consumer end will drive solar power capacity additions given the acute power shortages in several states.
