基于Hotelling模型的充电服务费双寡头联盟定价方法

为了减少电动汽车充电负荷大规模接入对电网安全稳定运行的负面影响,针对含有多主体运营商充电站的充电市场竞争定价问题,提出了基于Hotelling模型的充电服务费双寡头联盟定价方法。首先,分析了多元充电市场中电网公司、充电站运营商和电动汽车用户各自的利益追求。其次,利用Hotelling模型刻画了充电需求受价格引导的分布特性,设计了多元活性充电市场中的充电站运营商充电服务费定价方案。最后,通过仿真算例分析,验证了所提充电服务费双寡头联盟定价方法的有效性。

Pricing method of charging service fee duopoly alliance based on Hotelling model

In order to reduce the negative impact of large-scale access of electric vehicle charging load on the safe and stable operation of the power grid, a Hotelling model based duopoly alliance pricing method for charging service fee is proposed to solve the problem of charging market competition pricing with multi-agent operator charging stations. Firstly, the respective interests of power grid companies, charging station operators and electric vehicle users in the multi-charge market are analyzed. Secondly, the Hotelling model is used to describe the distribution characteristics of charging demand guided by price, and a charging station operator charging service fee pricing scheme in the multi-active charging market is designed. Finally, the validity of the proposed pricing method for charging service fee duopoly alliance is verified by simulation analysis.
