考虑多充电模式的充电桩优化控制策略

Optimized control strategy of charging piles considering multiple charging modes

出于对用户不同充电需求的考虑,市场上出现了具有多种充电模式的充电桩,增加了电动汽车充电控制的复杂性。针对区域内数量确定的充电桩,文中研究了针对具有多种充电模式的充电桩的控制策略。首先,根据充电桩和电动汽车的匹配结果,建立了充电桩的负荷状态向量;其次,根据系统是否需要考虑调峰需求响应,提出了不同的控制目标和控制策略;最后,以某实际工业园区为例,计及园区光伏出力、电池储能及分时电价等条件,进行仿真控制,对比分析了其在不受控、不考虑需求响应控制以及考虑需求响应控制3种情况下的结果,验证了文中控制策略的有效性。

In consideration of the different charging needs of users,the charging pile with multiple charging modes appears,increasing the complexity of electric vehicle charging control.Aiming at a certain number of charging piles with multiple charging modes,an optimized control strategy of charging piles is proposed.Firstly,according to the matching results of the charging piles and electric vehicles,the load state vector of the charging pile is established.Secondly,according to whether the control system needs to consider the demand response of the peak shaving,different control objectives and strategies are proposed.Finally,an actual industrial park is taken as an example.Considering the PV output,battery storage and time-of-use electricity price in the park,the results under the three conditions of uncontrolled,control without considering demand response,control considering demand response are compared,and the effectiveness of the proposed strategy is verified by simulation.
