Study of Inverter Controller in Saps system for Grid Connected Load

Abstract

Now a day’s solar, wind are the best alternative solution for meeting the energy demand especially in areas were electrification is an great issue. They are combine to develop a hybrid power station. The main issue that arises in hybrid power generation using renewable energy sources is the conversion efficiency and performance. A lot of research is going on to improve the power quality on controllers and converters. Also lots of optimization techniques have been developed so far for maximizing the performance & minimizing the cost. This project is focused on the control structure of grid connected inverter as it is the important section for transmission &conversion of energy to meet grid requirement for interconnection. In this project, a simulation of grid connected control of converter is presented for hybrid power generation. The structure for the control at grid-side inverter is firstly discussed. Secondly, the space vector modulation SVM is presented. Thirdly, the synchronization for grid-connected inverters is discussed. Finally, the simulation of the grid-connected inverter system using PSIM simulation package and the system implementation are presented to illustrate concepts and compare their results.
