POWER MANAGEMENT OF SOLAR BASED DCMG SUPPORTED BY HYBRID ENERGY STORAGE SYSTEM

The integration of renewable energy sources, particularly solar power, into the grid has gained significant attention due to its environmental benefits and potential to address energy demands. However, the intermittent nature of solar power necessitates efficient energy storage solutions to ensure a reliable and sustainable power supply. This paper investigates the power management strategies for a Direct Current Microgrid (DCMG) powered by solar energy and supported by a Hybrid Energy Storage System (HESS). The HESS comprises batteries and supercapacitors, each with distinct characteristics and advantages. The proposed power management system aims to optimize the utilization of solar energy, minimize energy losses, and ensure the stability of the DCMG. The system employs a combination of advanced control techniques, including model predictive control (MPC) and rule-based strategies, to coordinate the energy flow between the solar source, HESS, and load. Through simulations and experimental validation, the effectiveness of the proposed system in improving the overall performance of the solar-powered DCMG is demonstrated.
