要約(英語): As the penetration of renewable energy sources (RES) such as solar photovoltaic (PV) increases, the efficient management and control of microgrids have become paramount. In this paper, we present a novel approach to microgrid operation optimization, integrating both critical and non-critical loads with a Battery Energy Storage System (BESS) to maximize energy efficiency and economic performance. We propose an innovative load-shedding strategy to selectively disconnect non-critical loads during peak demand or scarce generation periods, thereby ensuring the supply to critical loads. Furthermore, we incorporate an optimal charging and discharging strategy for the BESS, aiming to smooth out the power fluctuations and to minimize the cost of energy from the grid. The proposed framework is based on a linear optimization model, which determines the optimal power flows from the grid, PV, and BESS to the loads, respecting the constraints of the BESS and the power grid. The model takes into account the BESS State of Charge (SOC), PV generation, load demand, and electricity price profiles. Preliminary results show that our approach can significantly reduce the total operational cost of the microgrid, improve the stability of power supply, and increase the self-consumption of locally generated solar power. This study provides valuable insights for utility companies and microgrid operators to design and manage their energy systems in an economically and technically feasible manner.
