Electric vehicle charging real-time pricing method based on game theory

Abstract

The invention relates to an electric vehicle charging real-time pricing method based on the game theory, and the method comprises the steps: dividing one day into a plurality of time periods, formulating the initial charging price of each time period at the first game round, and obtaining the load response strategy of each electric vehicle user; in a current game round, according to the load response strategy of the electric vehicle user in the last game round, adjusting the charging electricity price of each time period, the electric vehicle user responding to the price strategy of the charging station according to the charging demand condition of the electric vehicle user and entering the next game round, and balancing the game when the income of the electric vehicle charging station andthe total charging cost of the electric vehicle user in one day are optimal. Compared with the prior art, the electric vehicle charging real-time pricing method based on the game theory considers thepeak shaving effect of the charging station, the charging electricity price formulated by the electric vehicle charging station reflects the charging station load change level in real time, the powergrid side load level can be effectively improved, and the economic benefits of both parties of the game are improved.

Description

technical field [0001] The invention relates to a pricing method for electric vehicle charging, in particular to a real-time pricing method for electric vehicle charging based on game theory. Background technique [0002] Today's society pays more and more attention to energy and environmental issues. Electric vehicles are supported and promoted by governments of various countries because of their advantages such as clean environmental protection, high efficiency, energy saving and low noise. As a new type of load, disorderly charging of electric vehicles will increase the peak-to-valley load difference on the grid side, reduce the life of transformers, and increase network losses. Orderly charging of electric vehicles can participate in grid auxiliary services and optimize grid operation. A reasonable and effective charging pricing method can guide electric vehicle users to change their inherent charging habits, respond to the scheduling of charging stations, and reduce the...

AI Technical Summary

Problems solved by technology

The research on electric vehicle charging electricity price mainly focuses on the two aspects of time-of-use electricity price and dynamic time-of-use electricity price. Although it can reduce the charging cost of electric vehicle users and improve the load level of the grid side to a certain extent, with the continuous increase of the number of electric vehicles, The charging of a large number of electric vehicles in the trough period of the time-of-use electricity price is likely to cause new load peaks, and it is particularly important to adjust the charging electricity price of electric vehicles in a timely manner according to the current load changes at the charging station
