POWER QUALITY IMPROVEMENT USING STATCOM WITH RENEWABLE ENERGY SOURCE

Abstract

     The  renewable  energy  sources  play  an  important  role  in  electric power  generation  with  growing  environmental  concerns. The  inter connection of  renewable energy  sources  are  incorporated using power electronics converters, with the aim of improving power quality at the point of common coupling (PCC). STATCOM is used for reactive power compensation. Voltage source inverter with a DC link capacitor is called STATCOM. STATCOM and renewable energy resource are interfaced with each other in this project. Thus, STATCOM is used innovatively as a load reactive power compensator and an interface unit between the load and renewable energy resource. Multiple control units used for controlling the STATCOM and renewable energy resource separately, are replaced by a single controller unit as they are interfaced with each other. By the above proposed idea, real and reactive power flow would be controlled with help of single voltage source inverter. Switching losses will be reduced due to absence of multiple converters. Overall cost of system will be reduced.
