Charging station pricing method considering vehicle party, station party and network party

Abstract

The invention relates to a power system technology, in particular to a charging station pricing method considering a vehicle party, a station party and a network party. The method comprises the following steps: establishing an optimal power flow model of a power distribution network by taking minimum load fluctuation as a target; establishing a charging station ordered charging scheduling model bytaking the maximum revenue of a charging station as a target; establishing an electric vehicle user decision model by taking the minimum charging cost as a target; converting a three-party game modelof a vehicle, a station and a network into a single-layer optimization model through a master-slave game model; converting the single-layer optimization model into a convex optimization model througha second-order cone relaxation and polyhedron approximation strategy; and solving the convex optimization model for multiple times through a standardization method to obtain a vehicle, station and network three-party game equilibrium solution so as to formulate the charging price. According to the method, a fair pricing method is provided, fairness of a charging electric energy transaction marketcan be improved possibly, ordered interaction among an electric vehicle user, a charging station operator and a power distribution network operator is promoted, and win-win of a vehicle, a station and a network is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, and in particular relates to a charging station pricing method considering the three parties of vehicles, stations and networks. Background technique [0002] Compared with traditional cars, electric vehicles have less impact on the environment, and their prospects are widely optimistic. The technology is relatively simple and mature, and it can be charged wherever there is a power supply. The cost of using electric vehicles, some are more expensive than cars, and some are only 1 / 3 of the price of cars, which mainly depends on the life of the battery and the local oil and electricity prices. [0003] In the electricity market environment, electric vehicles, charging stations, and power grids belong to different stakeholders. Electric vehicles need to meet the travel needs of users. Safe, economical and efficient operation. The key to dispatching electric vehicles to participate ...

AI Technical Summary

Problems solved by technology

[0004] At present, the research on the charging and discharging electricity price of electric vehicles mainly focuses on the orderly charging behavior under the "vehicle-network" interaction mode dominated by the power grid, and does not consider the multi-level interaction of "vehicle-station-network" under the market equal subject transaction mode.
