MODELLING AND SIMULATION OF GRID CONNECTED SYSTEM FOR EFFICIENT POWER MANAGEMENT

Photovoltaic (PV) systems proposes attractive alternative source of generation because these can be placed near to the
load centers when compared with other renewable source of generation. Most of renewable energy systems works in
conjunction with the existing electrical grids. Also, inverter technology has an important role to have a safe and reliable grid interconnection operation of renewable energy systems. It is also necessary to generate a high quality power to the grid with reasonable cost. They also must be capable of provide high efficiency conversion with high power factor and low harmonic distortion. For this reason, the control policy must be considered. Therefore, The most important current control techniques are investigated in this paper. his project mainly focuses on the conversion of excessive solar energy into useful power to eliminate the power scarcity, where the solar power can be converted into electricity and can be synchronized with the grid. The solar power is trapped with the help of solar cells, which will produce a DC voltage. This DC voltage will be converted into AC using IGBT based three phase six pulse inverter. Filters are used to remove the higher order harmonics present in the signal inverter output signal. This filtered AC voltage can be synchronized with the grid.
