Operation characteristic analysis of Three-phase grid connected PV system with AF and STATCOM

The works on the distributed generation systems, such as photovoltaic (PV) power generation system connected to the power grid, has increased in the last decades due to need of supplying the rising worldwide demand for electric power. The utility is created an adverse effect through variety loads. So, this paper presents a three phase grid-connected PV power generation system with active filter (AF) and static synchronous compensator (STATCOM). This system contains an AF function for harmonic currents compensation and a STATCOM function for reactive power compensation without extra devices. The operational characteristics of a grid connected PV system were verified by a fabricated system. Simulation and experimental results are presented to validate the proposed methodology for grid connected PV generation power system.
