摘要： The environmental effect and need of energy have been increasing rapidly, due to this demand for renewable resources increased. One of the renewable resources Solar Photovoltaic (PV) energy is presently most popular in the environment. An inverter is a necessary part of grid-connected PV systems. This paper presents a new approach of large-scale photovoltaic solar farm inverter as STATCOM, known as PV-STATCOM, for regulation of voltage at the point of common coupling which recovers the voltage stability of the transmission line. Over daytime, the solar PV farm generates active power, but stay in idleness at the night-time. In this paper, PV-STATCOM incorporating multilevel inverter is presented. The voltage at the PCC is regulated at different loading conditions using PV-STATCOM. The entire system modeling and study are performed using MATLAB/SIMULINK.
