Electric vehicle charging station planning method based on gravitation search algorithm

Abstract

The invention relates to the technical field of electric vehicles, particularly discloses an electric vehicle charging station planning method based on a gravitation search algorithm. The electric vehicle charging station planning method based on the gravitation search algorithm comprises the steps of obtaining the related information of a planning area, wherein the related information comprises the planning area traffic network information, the planning area power distribution network informatization and the electric vehicle driving range information; estimating the range of the number of charging stations in the planned area; calculating the whole social cost of all charging stations in the planned area according to a gravitation search algorithm; comparing all the social costs of all the charging stations to obtain a planning scheme corresponding to the lowest cost. According to the electric vehicle charging station planning method based on the gravitational search algorithm, the charging station can be reasonably planned in a city with insufficient land, the requirement for safe operation of a power distribution network is met, and the rapid and convenient charging service canbe provided for vehicles.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method for planning electric vehicle charging stations based on a gravitational search algorithm. Background technique [0002] Electric vehicles (Electric Vehicles, EVs), as a means of transportation gradually promoted by the modern automobile industry under the background of fossil energy crisis and environmental pollution, are favored by the world for their good environmental and social benefits such as zero exhaust emissions and low noise pollution. wide attention from all over the world. Perfect charging facilities are a prerequisite for the promotion of electric vehicles. Experts have confirmed that among the many factors affecting the development of electric vehicles, the importance of charging facilities is second only to battery technology. Unreasonable planning of charging infrastructure will lead to idle charging stations, waste or overcrowded charging sta...

Problems solved by technology

From the perspective of service facilities, the planning of electric vehicle charging stations should meet the charging needs of users as much as possible, so that users can quickly and conveniently complete charging in the shortest possible time; The power grid needs to supply power to the charging station through the distribution transformer. Because the charging current of the charging station is large and the charging load has an obvious peak period, after connecting to the distribution network, it will cause adverse effects such as node voltage fluctuations and feeder current exceeding the line capacity. Therefore, its The planning must meet the requirements for the safe operation of the distribution network
