The invention provides an electric vehicle charging station operation control system and method, and relates to the technical field of charging station operation control, and the system comprises a diesel generator set, a photovoltaic array, a storage battery, a voltage source converter, a boost converter, and a bidirectional DCDC converter. By optimizing a control strategy, firstly, the electricquantity of a solar photovoltaic and battery energy storage system is used, then a power grid is used, and finally, when other forms of charging are not available, a diesel generator set is used for generating power, so that the reliability of the charging station is improved by the charging station operation strategy, and the operation cost of the charging station is favorably reduced. Accordingto the invention, the problem that multi-energy charging minimum cost control and continuous charging cannot be realized in the prior art is solved, uninterrupted charging is realized by using the priority use principle of different energy sources, the reliability of the charging station is improved, and the operation cost of the charging station is reduced.
本公开提供了一种电动汽车充电站运行控制系统及方法,涉及充电站运行控制技术领域,包括柴油发电机组、光伏阵列、蓄电池、电压源变换器、升压变换器和双向DCDC变换器;通过优化控制策略,首先使用太阳能光伏和电池储能系统的电量,然后使用电网,最后当其他形式的充电不可用时,再使用柴油发电机组发电,这种充电站运行策略增加了充电站的可靠性,有助于降低充电站的运行成本;本公开解决了现有技术中无法实现多能源充电最小成本控制和连续充电的问题,利用对不同能源的优先使用原则,实现了不间断充电,增加了充电站的可靠性,降低了充电站的运行成本。
