Problems solved by technology
However, the existing collaborative methods do not consider the enthusiasm of electric vehicle charging stations to participate in joint planning.
The joint planning adjusted the optimal construction location and capacity of the charging station, resulting in an increase in the land scale of the electric vehicle charging station and a decline in the satisfaction of charging services, which further led to the lack of enthusiasm for the electric vehicle charging station operators to participate in the joint planning

The invention discloses an electric vehicle charging station and power distribution system joint planning method based on a cooperative game. The method comprises the following steps: calculating a satisfaction index of an electric vehicle charging station and a power distribution system in a process that the electric vehicle charging station accesses the power distribution system; considering the safe operation constraint of the power distribution system, and constructing an electric vehicle charging station and power distribution system joint planning model; based on the cooperative game model, reasonably distributing the surplus generated by the joint planning between the electric vehicle charging station and the power distribution system by adjusting the electricity selling price of the power distribution system to the electric vehicle charging station. According to the electric vehicle charging station and power distribution system joint planning method based on the cooperative game, the satisfaction index of each participant in electric vehicle charging station and power distribution system joint planning is researched and displayed; and on the basis of the cooperative game model, the feasibility of joint planning of the electric vehicle charging station and the power distribution system is remarkably improved by adjusting the joint planning surplus distribution method of the electricity selling price from the power distribution system to the electric vehicle charging station.
Description
Technical field [0001] The present invention relates to the field of electricity systems, in particular, a combined planning method for electric vehicle charging stations and power distribution systems. Background technique [0002] The joint plan of electric vehicle charging station and power distribution system can effectively reduce the adverse effects of electric vehicle charging load access on power distribution systems. Through the reasonable adjustment of the position and capacity of the charging station, the load peak valley deviation of the power distribution system, the line load rate, and further reduce the scale and capacity of distribution transformers and distribution lines in power distribution systems. However, the existing synergistic approach does not consider the enthusiasm of the electric vehicle charging station to participate in joint planning. The joint plan adjusts the optimal construction position and capacity of the charging station, leading to an increa...
