Load control system and method for electric vehicle charging station

Abstract

The invention provides a load control system and method for an electric vehicle charging station, and the system comprises a power grid dispatching platform which is used for evaluating the load output which should be reduced in a target area in a target area according to the power utilization information and the line information, and enabling the load output to be a power grid demand; the transformer area intelligent fusion terminal is used for adjusting the load of the charging station in the target transformer area and monitoring the load of the charging station in the target transformer area; the charging station management platform is used for generating a user demand according to the charging user order and the service state information of the charging pile; and the charging station edge control terminal is used for summarizing the received power grid demand and user demand, generating power limit information of the charging pile, and carrying out power distribution according to the power limit information of the charging pile. The charging station edge control terminal is adopted as a summary decision of multi-party demands, the maximum power limit of the charging piles in the charging station is comprehensively obtained, and the charging station participates in real-time demand response of a power grid.

Description

technical field [0001] The invention relates to the technical field of load control for electric vehicle charging stations, in particular to a load control system and method for electric vehicle charging stations. Background technique [0002] The transformation of transportation electrification represented by new energy vehicles is growing rapidly, and the number of new energy vehicles in the country continues to rise. With the gradual popularization of electric vehicles and clean energy, the increase in the proportion of clean energy increases the randomness of power supply and the rapid growth of charging load. Electricity consumption Under the background that the contradiction between large randomness is gradually highlighted, higher requirements are put forward for the power supply capacity, power supply reliability and load regulation ability of the electric vehicle charging station as the power consumption node of the multi-link power grid of generation, transmission...
