Coordination Configuration of Microgrid Wind-Solar-Storage Based on Optimization Model

With growing global concern about climate change and sustainable development, the energy system is undergoing profound transformation. Traditional fossil energy sources are gradually being replaced by clean and renewable energy sources. The coordinated and optimized configuration of wind and solar storage in the park microgrid can realize the efficient use of renewable energy and reduce the consumption of fossil energy, thereby reducing carbon emissions and environmental pollution, and meeting the requirements of energy conservation, emission reduction and sustainable development. The average power supply cost per unit of electricity is 0.7304 yuan/kWh, Park B is 0.6413 yuan/kWh, and Park C is 0.6145 yuan/kWh. Then use greedy tactics and The hybrid integer linear programming model is used to formulate the optimal energy storage operation scheme. The optimal energy storage configuration scheme is 220 kW/1279 kWh in Park A, 256 kW/1227 kWh in Park B, and 261 kW/2066 kWh in Park C. The average power supply cost per unit of electricity was determined to be 0.4956 yuan/kWh. An in-depth analysis of its economy was conducted and the operational efficiency was evaluated. Through genetic algorithms and a mixed-integer programming model, considering the costs and efficiency of the energy storage system, the optimal energy storage configuration scheme for the combined parks was determined as 682 kW/1676 kWh.
