Abstract

The objective of this study is to develop an active power control of photovoltaic power generation (PV) system for supporting grid frequency regulation in two different forms, i.e. slow frequency control contributing to load - frequency control (LFC) and fast frequency control contributing to inertial response of synchronous generators. Two different active power - frequency droop characteristics are implemented simultaneously by using different frequency measurement methods. The performance test result of proposed control using an experimental setup shows that PV system equipped with proposed control can supply appropriate active power according to two different droop characteristics for slow frequency control and fast frequency control
