含多类型充电设施的城市电动汽车充电站群协同规划方法

A cooperative planning method of urban electric vehicle charging station group with multi-type charging facilities

为实现不同额定功率充电设施的有机组合配置,提出了一种含多类型充电设施的城市电动汽车充电站群选址定容规划方法。计及电动汽车用户的行为不确定性和需求多样性,设计了站内多类型充电设施协同服务水平模型;在此基础上结合充电需求分配和配电网约束,提出了考虑社会综合成本的含多类型充电设施的充电站群协同规划方法。所提的方法能够建模成混合整数二阶锥模型进行有效求解。通过耦合了地理信息及31节点配电网的某城市区域实际算例,验证了所提方法的合理性及有效性。

In order to organically configure charging facilities with different rated power,this paper proposes a siting and sizing planning method of urban EV charging station group,including multi-type of charging facilities.A cooperative service level model with multi-type charging facilities is designed considering the behavior uncertainty of EV users and the diversity of their demands.On this basis,a cooperative planning method of charging station group with multi-type charging facilities is proposed.This model also considers comprehensive social cost,combing with charging demand allocation and constraints of distributed network.The proposed optimization method can be modelled into a mixed-integer second-order cone model,which could be solved effectively.In this paper,an actual urban area example,which combines geographic information with a 31-node distribution network,is used to verify the feasibility and effectiveness of the proposed method.
