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.
