Abstract: This paper proposes an amplitude-based control of a solar photovoltaic (SPV) power generating system interfaced to a three-phase, four-wire distribution system, with the features of reactive power compensation for power factor correction (PFC) and zero voltage regulation (ZVR) with neutral current mitigation of other loads connected at the point of common coupling (PCC). This control algorithm is used to extract the fundamental currents from the load currents for estimating reference grid currents. Simulation results are presented to demonstrate the neutral current compensation, PFC and ZVR of the system.
Keywords: solar energy; solar power generation; photovoltaics; zero voltage regulation; ZVR; power factor correction; PFC; reactive power compensation; amplitude based control; simulation.
