Abstract :
As photovoltaic (PV) penetration is gaining its momentum in the recent past, grid codes will demand contribution by PV systems to frequency regulation. This paper presents an investigation into the frequency regulation aspect of photovoltaic systems. An inertial response from photovoltaic system is derived by making it to work away from MPPT point of operation. The case of frequency response under deloaded operation with frequency regulation is compared with the case when the photovoltaics are not contributing to frequency regulation. A microgrid with a conventional synchronous machine and six photovoltaic generators in a distributed scenario is considered for the study.
