Problems solved by technology
[0005] The control strategy of this method can improve the matching degree of electric vehicle charging power and energy generation power, reduce the network loss of the distribution network, and balance the electric vehicle charging load with the station area load. Charging willingness, etc., when applied in actual production, the charging load analysis factors are not considered comprehensive enough, and the feasibility is poor

The invention discloses a power distribution area electric vehicle charging load analysis method and device. The method comprises the following steps: collecting charging data of charging piles in a power distribution area; processing the charging data to obtain the charging state distribution of the electric vehicle; acquiring basic load data of a power distribution area, and determining the electricity price of each time period within one day according to the basic load data; according to the charging state distribution of the electric vehicle and the electricity price of each time period, establishing a charging and discharging model with the minimum user charging cost and the minimum load variance of a power distribution area; optimizing the charging and discharging model based on a particle swarm algorithm to obtain an optimal charging scheme of the electric vehicle; according to the method, the load of the power distribution area and the charging load of the electric vehicle can be balanced on the basis of fully considering the charging willingness of the user, the charging cost of the user is saved, the accuracy of an analysis result is high, and the method is more reasonable and high in feasibility.
Description
technical field [0001] The invention relates to the field of electric vehicle charging, in particular to a method and device for analyzing electric vehicle charging load in a distribution station area. Background technique [0002] With economic development, people pay more and more attention to environmental issues. On this basis, low-polluting electric vehicles emerged as the times require, but in recent years, the rapid development of electric vehicles has brought about increasingly prominent problems. Most electric vehicles will be charged when the user has no travel needs, and there will be large-scale charging at this time, resulting in unstable operation of the power grid. In addition, unlike the existing fuel vehicles, the charging of electric vehicles is a periodic process, which is full of randomness, such as the fluctuation of charging electricity price caused by the early departure or delayed departure of vehicles. Uncertainty, which makes it difficult to estab...
