Intra-regional electric vehicle charging scheduling method based on game theory

Abstract

The invention discloses an intra-regional electric vehicle charging scheduling method based on a game theory. The method comprises the following steps: 1) designing a new electric vehicle allocation criterion based on user charging cost; 2) giving an optimization problem of each intelligent charging station in the region by taking charging station income and ideal automobile capacity of the charging station as a comprehensive target; 3) according to the proposed optimization problem, modeling a competitive relationship among the multiple charging stations by utilizing a game theory; 4) demonstrating the existence of pure strategy equilibrium points of the game model defined in the step 3), and giving definition of Nash equilibrium and existence conditions of pure strategy Nash equilibrium;and 5) solving Nash equilibrium by combining an iterative search method and a particle swarm algorithm. According to the invention, the constraint of the ideal capacity of each charging station is considered while the profit of each charging station is satisfied for the intelligent charging station with relatively strong networking communication capability and calculation capability, the scheduling speed is high, the real-time performance is good, the problem of malicious competition among the charging stations is solved, and the balanced utilization of charging resources is achieved.

AI Technical Summary

Problems solved by technology

The traditional electric vehicle charging stations currently built have problems such as untimely service, high labor costs, untimely operation and maintenance and response, and cannot meet user needs. important

[0003] Charging stations cannot be independently dispatched according to user needs, and electric vehicles are charged out of order, which leads to huge differences in the utilization rate of existing charging stations. Some charging station resources are in short supply, while some charging stations are unattended, resulting in a waste of charging resources.
