Scheduling control method for participating power distribution network voltage regulation by electric vehicles

Abstract

The invention discloses a scheduling control method for participating power distribution network voltage regulation by electric vehicles. A scheduling optimization model of an electric vehicle charging station is established by using power distribution network voltage stability, electric vehicle charger technical condition, electric vehicle user charging requirement and the like as constraint conditions and using profit maximization as an objective function, then an optimal scheduling method for participating power distribution network voltage regulation by the electric vehicles is obtained on this basis, and scheduling for the electric vehicles is completed through the optimal scheduling method, so that the quantity of the electric vehicles connected into the charging station is increased, and safe and stable operation of a power distribution network is also maintained.

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 ...
