Performance comparison of shunt active filter interfacing algorithm for renewable energy sources

The renewable energy source interfacing with grid is the major issue in the electric utility side. The various types of grid interfacing converter topology have been proposed by researchers to improve quality of power and efficiency of the system. This paper focuses the shunt active filter interface for the renewable energy source with an efficient modified IcosΦ algorithm for controlling the grid /source side power flow and renewable energy power with linear static loads. The proposed shunt active filter interfacing algorithm is compared with the well known algorithm of Instantaneous Reactive Power Theory (IRPT) with modifications for reactive power compensation and real power control from the renewable energy source. The performance of the both the algorithms have been simulated and tested in MATLAB/Simulink.
