Enhancing microgrid renewable energy integration at SEKEM farm

Abstract

This study explores the feasibility of implementing a hybrid microgrid system powered by renewable energy sources. Including solar photovoltaics, wind energy, and fuel cells to ensure a reliable and sustainable electricity supply for the SEKEM farm in WAHAT, Egypt. The study utilizes MATLAB/Simulink software to conduct simulations based on sun irradiation and wind speed data. Various control techniques, such as the proportional-integral (PI) controller, Fuzzy Logic Controller for PI tuning (fuzzy-PI), and neuro-fuzzy controllers, were evaluated to improve the performance of the microgrid. The results demonstrate that the Fuzzy-PI control strategy outperforms the alternative control systems, enhancing the overall dependability and long-term viability of energy provision. The hybrid system was integrated with a voltage source control (VSC) and fuzzy PI controller, which effectively addressed power fluctuations and improved the stability and reliability of the energy supply. Furthermore, it provides insightful information on how to design and implement a 100% renewable energy system, with the fuzzy PI controller emerging as a viable method of control that can guarantee the system’s resilience and outperform other approaches, such as the standalone PI controller and the neuro-fuzzy controller.
