Introduction
This project proposes an enhanced control scheme for a Unified Power Quality Conditioner (UPQC) to improve power quality in wave energy conversion systems using Permanent Magnet Synchronous Generators (PMSG). The UPQC combines series and shunt compensators to mitigate voltage sags, swells, flicker, and harmonic distortions present in the grid due to wave energy intermittency. The enhanced control algorithm optimizes compensator performance, ensuring stable voltage and current waveforms, improved reactive power compensation, and reduced power quality disturbances.
