In order to further enhance the economic efficiency and environmental performance of microgrid systems, a coordinated optimal scheduling strategy for a microgrid incorporating the participation of electric vehicles and ice storage air conditioning systems was proposed. First, mathematical models of wind turbines, photovoltaic generators, diesel generators, energy storage systems, electric vehicles, and ice storage air conditioning systems in the microgrid were established. Then, considering constraints such as power balance and equipment output limits, an optimal scheduling model of the microgrid was constructed with the minimization of operation and maintenance costs and environmental governance costs as the optimization objectives, and the model was solved and analyzed using the Gurobi solver. The results show that, through a comparison of microgrid operation under different scenarios, the proposed optimal scheduling strategy increases the wind-solar energy accommodation rate by 2.59%, reduces environmental costs by 40.27%, and decreases operation and maintenance costs by 41.49%, thereby effectively improving the capability of renewable energy utilization and enhancing the environmental friendliness and economic performance of the microgrid system.

电动汽车(electric vehicles,EVs)与冰蓄冷空调(ice storage air conditioning,ISAC)作为可调节负荷资源,在增强微电网运行灵活性方面展现出巨大潜力。一方面,电动汽车是具备储能特性的移动负荷,可通过有序充放电技术(vehicle-to-grid,V2G)实现与微电网的双向电力交互[16-18]。具体而言,在满足车主用电需求的前提下,电动汽车集群可在电价低谷时段响应充电、在电价高峰时段反馈电力,从而实现负荷移峰填谷,平抑微电网的电力波动[19-21]。另一方面,冰蓄冷空调是可蓄冰储冷与融冰供冷的空调系统,基于这一特性,其可在夜间用电低谷时段运行制冷机制冰,在白天用电高峰时段融冰释放冷量以满足供冷需求,实现在时域上的电力负荷平移,进而缓解高峰时段的负荷压力[22-23]。因此,将电动汽车集群与冰蓄冷空调系统协同纳入微电网优化调度模型,对提升微电网调度灵活性具有重要意义。
