Voltage rise regulation with voltage source inverter in grid connected PV generation system

This paper discusses the voltage rise of photovoltaic power generation system (PVPGS) at the point of common coupling (PCC). It analyzes the reason of voltage rise and voltage regulation principle within the perspective of power transmission theory in power system. Particularly, It propose a effective solution—IQ(U) method to dynamically control of voltage at PCC. Theoretical analysis and experiment results are presented to validate the effectiveness of the proposed control scheme for voltage rise mitigation. It is expected that the presented solution can provide a useful theoretical basis and design reference for maximize the penetration of PVPGS.
