System and method for analyzing and determining influence of large-scale charging pile to community distribution system

Abstract

The invention discloses a system and method for analyzing and determining the influence of a large-scale charging pile to a community distribution system. The system comprises a monitoring centre for analyzing and determining the influence of the large-scale charging pile to the community distribution system and a data acquiring terminal for acquiring the data of the charging pile, wherein the data acquiring terminal communicates with the charging pile by a network. According to the invention, the community distribution system capacity model, a normal distribution model of the community power load and power time, and charging real-time data are combined, so as to compare the calculated community distribution load curve with the distribution system capacity model, so that the operation condition of the community distribution system is monitored, a coordination scheduling policy for the community distribution system operation is determined and the permeability of the community electric vehicle is assessed. Moreover, the charging behaviours of the community electric vehicle are controlled in a coordinated manner, the influence of the community electric vehicle to the distribution system and the electric energy quality is reduced, the permeability of the community electric vehicle is improved, and the community distribution system is ensured to safely and stably operate.

Description

technical field [0001] The invention belongs to the field of monitoring the impact of electric vehicle electricity consumption, and in particular relates to a system and method for analyzing and deciding the impact of a large-scale charging pile on a residential power distribution system. Background technique [0002] In order to solve the problems of environmental pollution and energy shortage, the development of electric vehicles has become a trend. More and more electric vehicles will enter the households of ordinary people. According to survey statistics, consumers prefer to charge at night when choosing charging methods. , and choose to charge themselves in residential areas, so it is imperative to equip residential areas with electric vehicle charging piles. Cities around the world have also begun to promote the work of charging piles entering communities, including expanding charging piles in established communities, and reserving installation locations for charging p...
