Isolated Grid Forming Control by Wave Energy Converter for Island Electrification
Keywords:
GAO, grid-forming, power quality, harmonics mitigationAbstract
This extension incorporates a Genetic Algorithm (GA) into the isolated grid-forming control framework to enhance power quality in a wave-energy-based island electrification system. Unlike traditional approaches that optimize controller gains, the proposed method embeds GA directly inside a MATLAB Function block to compute an improved reference signal based on error inputs. The generated VDG output influences the generator-side control, enabling better dynamic response. The base system achieves current and voltage THDs of 4.98% and 4.97%, while the GA-based extension reduces these to 3.84% and 3.90%. The results demonstrate that integrating GA as an intelligent control signal generator can effectively minimize distortion and enhance system performance.
