Abstract

An improved enhanced phase-locked loop (EPL)-based control algorithm for a double-stage solar photovoltaic (PV) grid-interfaced power generating system is presented in this article. It also mitigates power quality (PQ) problems in a three-phase, four-wire (3P4W) distribution system under variable solar intensity. The proposed solar PV grid-interfaced system consists of a solar PV array, a boost converter, a four-leg voltage source converter (VSC), and connected linear/nonlinear loads. The suggested improved EPL based synchronization method is implemented to meet grid requirements such as PQ improvement, distortion-free signals under variable solar intensity, and load unbalancing.
