Active and Reactive Power Control of Distributed Energy Generation System with DC Supply Source Using PI Controller

Alternative energy sources are seen as reliable substitutions to conventional energy sources in modern days because of their renewable and pollution-free properties. In this regard Distributed Generation (DG) has to play a vital role in the energy supplydemand realm. Consequently inverter technology has gained extreme importance and the study of the control structures of the inverter has become an important area of research. In this paper, a theoretical analysis, control and simulation of a grid connected three phase inverter has been given. The investigated control strategy is based on the feed forward current control method using conventional Proportional Integral (PI) controller in the synchronous rotating reference frame.
