基于纳什-哈萨尼博弈的配电网-交通网耦合运行模式

Coupled Operation Mode of Distribution-transportation Network Based on Nash-Hassani Game

  • 摘要: 目前风、光等可再生能源正以微电站、微储能和微能网的形式分布式地接入配电系统中。然而此类三微元素缺乏统筹的运营管理模式,导致配电系统光、车、储、网等元素存在不匹配的情况。为此,提出基于纳什-哈萨尼博弈的三微融合配电网-交通网耦合运行模式。首先,为解决交通网和配电网独立运行效率低下、网络堵塞等问题,建立配电网-交通网耦合系统,综合考虑交通网和电动汽车用户的多重信息,提出以出行时间和充电成本最小为目标的电动汽车最优充电路径模型。其次,建立三微融合配电网-交通网模型,包括配电网、交通网、微电站、微储能和微能网。然后,为鼓励三微元素之间的电力交易,提出一种基于纳什-哈萨尼博弈理论的激励机制,考虑各种因素对利益相关者议价能力的影响,根据其贡献将节省的收入分配给所有参与者。最后,通过对比与分析,验证了所提方案的有效性和优越性。

     

    Abstract: At present, renewable energy sources such as wind and solar are distributedly connected to the distribution system in the form of micro power station, micro energy storage and microgrid. However, these three micro elements lack a coordinated operation and management mode, resulting in mismatches among the solar, electric vehicle, storage and network elements of the distribution system. A coupled operation mode of three-micro integrated distribution-transportation network based on the Nash-Hasani game is proposed. Firstly, in order to solve the low efficiency and network congestion problems of independent distribution-transportation network, a distribution-transportation coupling network is established. Considering the multiple information of the transportation network and electric vehicle users, an optimal charging path model with the goal of minimizing travel time and charging cost is proposed. Secondly, a three-micro integrated distribution-transportation network model is established, including distribution network, transportation network, micro power station, micro energy storage and microgrid. Then, in order to encourage power trading among three micro elements, an incentive mechanism is proposed based on the Nash-Hasani game theory. The impact of various factors on the bargaining power of stakeholders is considered and the saved income to all participants is distributed according to their contributions. Finally, through comparison and analysis, the effectiveness and superiority of the proposed scheme are verified.
