Abstract

The invention discloses a coordinated control method and system considering optimal charging of an electric vehicle battery swap station. Under the guidance of time-of-use electricity price of a power grid, the minimum cost of the battery swap station is taken as a target, battery number balance and state transition constraints of the battery swap station are fully considered, a corresponding target function and constraint conditions are constructed, and according to the demand prediction of the current battery swap station, an optimal charging strategy of the battery swap station is made. The established coordinated control model is a positive number linear programming model, and compared with a nonlinear programming model with small power grid load fluctuation as an optimization target, the solution difficulty is reduced, and the technical problems that an existing battery swap station and power grid coordinated operation mode takes small power grid load fluctuation as an optimization target, the solving difficulty of load prediction is increased, and the practicability is low can be solved.

本发明公开了一种计及电动汽车换电站优化充电的协调控制方法和系统，在电网分时电价引导下，以换电站费用最小为目标，充分考虑换电站电池数量平衡和状态转移约束，构建对应的目标函数和约束条件，可依据日前换电站的需求预测，制定换电站的优化充电策略，本发明所构建的协调控制模型为正数线性规划模型，与以电网负荷波动小为优化目标的非线性规划模型相比，降低了求解难度，解决了现有的换电站与电网协调运行方式以电网负荷波动小为优化目标，增加了负荷预测的求解难度，实用性较低的技术问题。
