Improvement of Power Transfer Capability of Grid Employing Solar Farm as STATCOM

Abstract

This paper introduces a modem method of utilizing PV solar inverter as static synchronous compensator, for increasing power transfer capability of the interconnected grid. The solar farm generates active power at day time and totally idle at night time The entire PV farm utilizes voltage controller and damping controller for increasing power transfer capacity during the time period. The capacity of inverter left after the active power production at day time which is used to accomplish the above objectives This novel control concept of PV solar farm improves power transfer capacity, therefore other additional flexible AC transmission system controllers or series/shunt capacitors are not required
