Abstract
PV solar inverter plays essential role for generating the electricity at distribution end. A large scale PV generation includes photovoltaic array, DC/AC converters and related controllers. PV solar farm feed active power during day time and become inactive in the night time. The increasing penetration level of renewable based distributed generators causes a rise in voltage at point of common coupling (PCC) due to reverse power flow. To regulate voltage at PCC; utilities need to install voltage regulating devices like FACTs. In proposed work utilization of voltage source converter of PV solar farm as a STATCOM for grid voltage regulation at night time when there is no generation of PV farm. It avoids the other voltage compensating devices. A MATLAB/Simulink based simulation study is presented to validate the performance of proposed work.
