A Novel Photovoltaic Power Generation System including the Function of Shunt Active Filter
Park, Minwon,Seong, Nak-Gueon,Yu, In-Keun The Korean Institute of Electrical Engineers 2003 KIEE International Transactions on Electrical Mach Vol.b3 No.2
With significant development of power electronics technology, the proliferation of nonlinear loads such as static power converters has deteriorated power quality in power transmission and distribution systems. Notably, voltage harmonics resulting from current harmonics produced by the nonlinear loads have become a serious problem in many countries. Many photovoltaic power generation systems installed in building systems have harmonics that are the worst object for distribution systems as a utility interactive system, and it tends to spread out continuously. Proposed and implemented in this paper is a multi-function inverter control strategy that allows a shunt active filter function to the power inverter of the photovoltaic power generation system established on a building system. The effectiveness of the proposed system is demonstrated through the simulation of a hypothetical power system using PSCAD/EMTDC.
