分时电价下PHEV智能集中充电策略

以分时电价为背景,分析了未来插电式混合动力车(plug-in hybrid electrical vehicle,PHEV)通过"车辆到电网(vehicle to grid,V2G)方式接入电网可能带来的问题,提出了基于需求侧响应思想的V2G集中充电策略,分别从供电侧调峰角度和用户侧成本角度建立数学模型,提出一种基于动态估计插值思想的算法,最终采用纽约州长岛地区的数据进行算例仿真。结果表明,PHEV集中充电策略可以有效地减少峰谷差,节约用户充电成本,达到供电侧与用户侧的双赢结果。

Study on PHEV coordinated charging mechanism under TOU pricing

On the context of TOU electricity pricing market, combined with the characteristics of V2G confronted in the future, this paper mainly proposes a feasible PHEV centralized V2G charging mechanism, establishes separately utility’s off-peak load management model and PHEV terminal cost model. In accordance with the mechanism, this paper also puts forward an optimization algorithm based on dynamic estimate interpolation concept. At last, an example is simulated to illustrate the feasibility of the proposed model and algorithm.
