Online scheduling method and device based on electric vehicle charging demand response

Abstract

The embodiment of the invention provides an online scheduling method and device based on electric vehicle charging demand response. The method comprises the steps that: the electric quantity demand information of a plurality of first user terminals in each time slot in a preset time range, and the EDR (emergency demand response) information of a power grid are received, wherein the first user terminals are user terminals having a charging demand; based on the electric quantity demand information and the EDR information, the demand information is displayed to a plurality of second user terminals, response information returned by each second user terminal is received, wherein the response information comprises the electric quantity which can be provided by the second user terminals to the outside and the value of the electric quantity; an optimization model is constructed based on the electric quantity demand information, the EDR information, the response information and the information of a local generator; and an electric vehicle charging scheduling strategy under the time slot is determined for the first user terminals by using the optimization model. According to the online scheduling method and device based on the electric vehicle charging demand response of the invention, the charging requirement of an electric vehicle can be better met.

Description

technical field [0001] The invention relates to the technical field of power dispatching, in particular to an online dispatching method and device for electric vehicle charging demand response. Background technique [0002] With the increasing number of electric vehicles, electric vehicle charging stations have participated in the EDR (Emergency Demand Response, Emergency Demand Response) program due to their large energy consumption and wide distribution. In an EDR project plan, the charging station receives an EDR signal from the grid within a specific period of time. The EDR signal can indicate the upper limit of the power grid can provide, and then the charging station reduces its energy consumption for the grid demand to the grid. The provided power is below the upper limit to reduce the high load on the grid and protect the stability of the grid. At the same time, the charging station can obtain certain benefits from the grid accordingly. [0003] In practical applica...

[0004] However, in the EDR scenario, the power of the grid reaches the upper limit, and only the local generator is used as a remedy for the shortage of power resources and the imbalance between supply and demand, reducing the power that can be provided to electric vehicle users, so that the power required by electric vehicles cannot be met.
