Abstract

The limited supply of fossil fuels and the growing global energy demand create global energy challenges. Power production systems based on renewable energy have become more prevalent due to increased challenges. As renewable power sources become more prevalent, erratic environmental conditions increase uncertainty in power production, control, and operation. To cope with these weather conditions, some support systems, such as storage devices, use renewable energy sources (RES). The hybrid energy storage system (HESS) solves these microgrid problems by combining several storage devices. Power management and control are crucial for maintaining the robustness and reliability of microgrids. In this paper, the model considers different scenarios, such as varying load demands and intermittent renewable energy sources. Additionally, the effectiveness of the power management strategies is evaluated by analyzing the system's ability to maintain stable voltage levels and efficiently utilize storage devices. The results obtained from the MATLAB/Simulink simulation provide valuable insights into the effectiveness of these strategies and their potential for real-world implementation.
