Abstract
This paper presents a cost-effective Energy Management System (EMS) designed for microgrids integrating renewable solar energy and Superconducting Magnetic Energy Storage (SMES). The microgrid, simulated using MATLABSimulink, features photovoltaic (PV) panels for power generation and an energy storage system (ESS) to manage surplus energy. The study analyses two weather conditionsclear and cloudy daysusing real-time datasets to assess the system's performance. Two case studies were conducted: the first under clear day conditions, and the second under cloudy day conditions. Simulation results show fluctuations in Microgrid voltage and active power generation between PV, ESS, the grid, and loads. By applying a linear programming-based optimization approach, the EMS effectively manages the charging and discharging cycles, ensuring cost savings. Results demonstrate that under clear day conditions, the cost per day is reduced from $730 (without optimization) to $615 using the optimization approach while maintaining stable grid operations. Similar cost reductions are observed under cloudy day conditions, highlighting the superiority of optimization over heuristic methods. This work demonstrates the feasibility of using hybrid solar-SMES systems for efficient energy management in microgrids, providing optimized power generation and storage solutions while minimizing operational costs.
