Abstract

The invention discloses a genetic algorithm-based optimal design method for an electric vehicle quick charging station. The method comprises the following steps of generating an initial group througha chromosome structure; selecting an appropriate number of charging piles and rated power, and calculating the investment cost of the charging piles; calculating the power demand of the electric vehicle; selecting a proper number of wind driven generators and the surface area of the photovoltaic panel, and calculating the power generation power and investment cost; selecting an appropriate energystorage system capacity, and calculating the cost of the energy storage system; calculating the profit difference between the power consumption and the power supply after accessing the power grid; calculating a power supply profit for an electric vehicle user; and calculating a total profit function, and selecting optimal configuration according to a genetic algorithm. According to the method, profit differences caused by multiple variables such as the number and power of the charging piles of the electric vehicle quick charging station. The number of the wind driven generators, the surface area of the photovoltaic panel and the capacity of the energy storage system are considered. The optimal design of the electric vehicle quick charging station is determined according to the profit function. The economic benefit is improved, and the power grid pressure can be relieved.

Description

technical field [0001] The invention relates to an electric vehicle charging method, in particular to an optimal design method for a fast charging station for an electric vehicle based on a genetic algorithm. Background technique [0002] Due to the shortage of fossil energy and the impact on the environment during its use, the current trend of energy development is to develop and utilize new energy to reduce urban pollution and greenhouse gas emissions. As a result, the number of electric vehicles is expected to grow exponentially in the next few years. At present, one of the most important problems in the development of electric vehicles is the insufficient charging infrastructure and the charging time is too long. Therefore, the design and installation of fast charging stations has become one of the main issues and challenges faced by the electric vehicle industry. [0003] In fast charging stations, electric vehicle batteries can be fully charged in about 15 minutes, a...
