The invention relates to an energy coordination control method for an optical storage charging station. The optical storage charging station comprises a photovoltaic power generation system, an energystorage battery system, an alternating-current power distribution network system, a direct-current bus, a direct-current charging pile and an energy coordination control system. The beneficial effects of the invention are that: in the present invention, an energy storage battery mode switching control strategy is designed; the problem that the energy of the energy storage battery is rapidly exhausted under the traditional control strategy is solved, the simulation result shows that the energy storage battery is kept fluctuating near the middle SOC area, frequent switching of the modes of theenergy storage battery is effectively reduced, the load of a power grid can be effectively reduced under the discharging mode, and the discharging depth of the energy storage battery is reduced.
本发明涉及本发明所提供的一种光储充电站能量协调控制方法,涉及的光储充电站包括:光伏发电系统、储能电池系统、交流配电网系统、直流总线、直流充电桩、以及能量协调控制系统。本发明的有益效果是:在本发明中,通过设计的储能电池模式切换控制策略,解决了传统控制策略下储能电池能量迅速耗尽的问题,仿真结果表明储能电池保持在中间SOC区域附近波动,并有效减少了储能电池模式的频繁切换,在放电模式下能够有效减轻电网的负荷,以及降低了储能电池的放电深度。
