Abstract

A Wave Energy Converter (WEC) harnesses ocean wave motion to generate electrical energy, with the Hydraulic Power Take-Off (HPTO) system playing a crucial role in converting this motion into usable power. This study explores the use of the Genetic Algorithm (GA) to optimize key HPTO parameters. By mimicking the process of natural evolution, GA effectively estimates the optimal parameters for enhancing system performance. The research demonstrates that a hydraulic motor with a displacement of 71 cc/rev, under an input force of 40,000 N, produced 41.5 kW in a single-point configuration and 104 kW in a multi-point setup, emphasizing the importance of selecting the right motor displacement. Furthermore, increasing the number of absorbers in the system significantly boosted overall performance, with the multi-point configuration showing superior energy capture and mechanical power output. These findings highlight the critical role of optimization and system configuration in improving HPTO efficiency and offer valuable insights for future WEC designs aimed at maximizing energy conversion.
