基于微电网的电动汽车换电站运营策略

Operation Strategy for Battery Swap Station of Electric Vehicles Based on Microgrid

提出了一种基于微电网的电动汽车换电站运营模式,建立了换电站充放电模型。根据换电站内充放电装置和电池组的约束,结合含有风电、光伏、燃料电池、微型燃气轮机、柴油发电机等电源的微电网,提出了含电动汽车换电站的微电网优化调度策略,并将换电站接入模式与传统储能电站接入模式进行了对比。算例表明,换电站也可以发挥削峰填谷的作用,且更具经济性。最后对市场容量、换电池价格及可再生能源渗透率等因素对经济性的影响进行了分析,提出的激励指数可为换电池价格、电池租赁价格的制定提供参考。

An operation mode for battery swap station （BSS） of electric vehicles based on the microgrid is proposed and a charging and discharging model of BSS is developed. According to the constraints of charging and discharging device battery and battery pack in BSS, a new optimal dispatching strategy for the microgrid containing BSS, wind generators, photovoltaic systems, {uel cells, microturbines and diesel generators is given. The economic indites of the BSS mode are compared with those of the traditional energy storage station （ESS） mode, and the simulation results show that BSS can bring more benefits than ESS. Furthermore, the economic impact of battery renting market capacity, the price of batteries and penetration of renewable energy are also discussed. The incentive indices proposed can provide a reference for the pricing of battery swap and renting.
