A dispatch control method for electric vehicles to participate in distribution network voltage regulation

Abstract

The invention discloses a scheduling control method for electric vehicles to participate in the voltage regulation of distribution networks. The voltage stability of the distribution network, the technical conditions of electric vehicle chargers, and the charging needs of electric vehicle users are taken as constraints, and the maximum profit is established as an objective function. The scheduling optimization model of electric vehicle charging stations is established, and then the optimal scheduling method for electric vehicles participating in distribution network voltage regulation is obtained on this basis, and the scheduling of electric vehicles is completed through this optimal scheduling method, which not only improves the charging station access The number of electric vehicles also maintains the safe and stable operation of the distribution network.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and more specifically relates to a scheduling control method for electric vehicles to participate in voltage regulation of distribution networks. Background technique [0002] In order to reduce environmental pollution and prevent resource depletion, energy conservation and emission reduction have become the consensus of governments and energy companies on environmental development, and have also become the main direction of the development of the automobile industry. Electric vehicles are considered to be the future of the automobile industry. Automobiles have developed extremely rapidly in recent years. The simultaneous charging of a large number of electric vehicles will lead to a sharp increase in the load of the distribution network, which will cause a drop in the voltage of the distribution network, resulting in negative effects such as low voltage, and even lead to severe events ...
