摘要
在考虑电动汽车主动充电响应的基础上,提出了电动汽车充电站-配电网协同规划模型。电动汽车作为典型直流负荷,具有主动响应特性,将之作为规划考虑因素,对电动汽车进行分时段电价调整,引导用户主动响应充电电价变化,由峰时充电向平时和谷时转移,可降低变电容量。另外,利用直流馈线代替部分交流馈线以满足电网中增加的直流负荷,降低电网中的馈线投资,共同降低了总规划成本。最后采用混合整数线性规划方法,通过CPLEX对该优化问题进行求解,并通过13节点配电网系统对交流配网和交直流配网分别进行了对比分析,对所提方法进行了仿真验证。
Based on the active charging response of electric vehicles, this paper proposes a collaborative planning model of “electric vehicle charging station-distribution network”. As a typical DC load, the electric vehicle has the characteristics of active response which can be used as a planning consideration factor to adjust the electricity price of the electric vehicle in a time-sharing manner, guiding the user to actively respond to the change of the charging price, and shifting charging demand from peak to off-peak periods, which can reduce substation capacity. In addition, this paper uses DC feeders to replace part of AC feeders to meet the increased DC load in the grid, reducing feeder investment in the grid, as well as the total planning cost. In the end, the mixed integer linear programming method is used to solve the optimization problem through CPLEX, the 13-node distribution network system is used to compare and analyze the AC distribution network and AC-DC distribution network respectively, and the proposed method is verified.
