Problems solved by technology

On the one hand, the growing demand for electric vehicle charging is unbalanced with the development of charging facilities. It is difficult to increase the capacity of existing distribution stations. The peaks of the basic load overlap, and the problem of peak-on-peak is becoming more and more serious, seriously affecting the reliability and economy of the distribution transformer; a new approach
[0003] At present, the research on electric vehicle charging facilities mainly focuses on the site selection and fixed capacity of charging stations, and most of them are planned on the premise that the distribution network can be expanded and transformed, but there is a lack of research on the aggravation of regional power distribution peak-valley differences, load imbalance, V2G Research on issues such as load balancing is difficult to meet the growing demand for electric vehicle charging, and it is also unable to effectively utilize the load balancing capabilities of electric vehicle charging and discharging facilities

Abstract

The invention belongs to the technical field of charging, and particularly relates to an electric vehicle charging and discharging facility planning and configuration method for load balancing. The method comprises the following steps: S1, obtaining electric vehicle information and planning area distribution transformer load information, and modeling electric vehicle travel characteristics; S2, modeling a one-way ordered charging demand; S3, carrying out V2G schedulable charging and discharging electric quantity calculation modeling; and S4, constructing and solving an optimal configuration model of the charging pile. The load accommodating capacity and the balance regulation and control capacity of a distribution transformer in the planning area are enhanced, the reliability and economy of the distribution network in the planning area and the charging requirement of the electric vehicle are considered, and the distribution transformer transformation problem is relieved.

Description

technical field [0001] The invention belongs to the technical field of charging, and in particular relates to a method for planning and configuring electric vehicle charging and discharging facilities for load balancing. Background technique [0002] In recent years, my country's power load has been increasing. At the same time, with the development of the electric vehicle industry, the impact of electric vehicles on regional distribution transformers is increasing. On the one hand, the growing demand for electric vehicle charging is unbalanced with the development of charging facilities. It is difficult to increase the capacity of existing distribution stations. The peaks of the basic load overlap, and the problem of peak-on-peak is becoming more and more serious, seriously affecting the reliability and economy of the distribution transformer; A new approach. [0003] At present, the research on electric vehicle charging facilities mainly focuses on the site selection an...
