Research on Optimal Configuration of Charging Pile Considering Two-Way Demand of Users and Power Grid

针对当前电动汽车充电桩布局规划研究片面考虑用户便捷性或电网安全性而产生的供需不平衡问题,提出了一种考虑用户侧与电网侧双边需求的应用在分布式发电主导电网的充电桩优化配置模型。首先构建基于电动汽车充电行为分析的用户侧需求模型与基于能量管理的电网侧需求模型,其次以最小化经济成本与最大化能源利用率为目标,采用基于位移密度估计的强度帕累托进化算法对充电桩数量的优化配置模型求解,最后通过仿真算例,验证所提模型有效性。

In view of the imbalance between supply and demand caused by one-sided consideration of user convenience or power grid security in current research on the layout planning of electric vehicle charging piles,this paper proposed an optimal configuration model of charging piles applied in the leading power grid of distributed generation considering the bilateral need of user side and power grid side.Firstly,the user side demand model based on user behavior analysis and the grid side demand model based on energy management were constructed respectively;Secondly,in order to minimize the economic cost and maximize the energy utilization,the SPEA2 with shift-based density estimation algorithm was used to solve the optimal allocation of the number of charging piles;Finally,an example was given to verify the effectiveness of the proposed model.
