Optimizing renewable energy harvesting in DC microgrid systems is achieved through the application of intelligent control strategies. By integrating solar photovoltaic (PV) systems, wind energy conversion systems (WECS), and battery storage within a hybrid renewable energy system (HRES), the aim is to boost energy efficiency and sustainability. The use of DC-DC converters is essential for stabilizing and synchronizing the variable DC outputs from solar and wind sources before they are combined into a common DC link. Various control techniques, including Fuzzy Logic Control (FLC) and Perturb and Observe (P&O) for Maximum Power Point Tracking (MPPT), are examined to ensure optimal power extraction from renewable sources. Simulation models developed in MATLAB/Simulink assess the system’s performance under different irradiance and wind velocity conditions, showcasing the effectiveness of intelligent control strategies in maximizing renewable energy utilization. The findings emphasize the significance of intelligent control in improving the efficiency and reliability of DC microgrid systems powered by renewable energy sources.
