The invention belongs to the technical field of electric energy storage systems, and particularly relates to an optimization method and system for a fast charging station battery energy storage system, and the method comprises the steps: optimizing and building a fast charging station profit maximization objective function according to the cost of the fast charging station battery energy storage system; and calculating the electric quantity transaction conditions of the photovoltaic system, the energy storage system and the power grid and the battery charging power of each EV during the charging period of the electric vehicle through the battery energy storage constraint condition of the fast charging station and the profit maximization objective function. The fast charging station battery energy storage system is effectively operated through a control strategy, and remarkable economic benefits are brought; and meanwhile, the peak load of a low-voltage feeder line during charging of the electric vehicle can be reduced.
本发明属于电能储能系统技术领域,具体涉及一种用于快充站电池储能系统的优化方法及系统,包括:根据快充站电池储能系统的成本,优化建立快充站利润最大化目标函数;通过快充站电池储能约束条件和所述利润最大化目标函数,计算电动汽车充电期间光伏、储能系统和电网电量交易情况及每个EV的电池充电功率。通过控制策略有效的运营快充站电池储能系统,带来显著的经济收益;同时,有助于减少电动汽车充电时低压馈线的峰值负荷。
