Abstract

The invention discloses an electric vehicle charging and discharging scheduling method based on consideration of an average discharging rate, and the method comprises the following steps: S1, collecting EV information of network access through an intelligent charging device, and carrying out the processing and screening of the EV information, and obtaining schedulable vehicle information; s2, establishing a first-stage optimization model; s3, obtaining optimized payment cost and average discharge rate indexes according to the first-stage optimization model and the constraint conditions of thefirst-stage optimization model; s4, taking the optimized payment cost and the average discharge rate index as constraint conditions, and establishing a second-stage optimization model; s5, collectingpower grid information and schedulable vehicle information through a cluster agent, and inputting the power grid information and schedulable vehicle information into the second-stage optimization model for scheduling optimization to achieve EV vehicle scheduling. The method solves the problems that in the prior art, charging and discharging scheduling is only carried out for power grid or user side requirements, and battery loss is not deeply considered when charging and discharging arrangement is carried out on the electric vehicle.

Description

technical field [0001] The invention relates to the field of electric power system planning, in particular to a charging and discharging scheduling method for electric vehicles based on taking into account the average discharging rate. Background technique [0002] In the context of energy shortage and environmental pollution issues, large-scale network access of efficient and clean electric vehicles will be an inevitable trend in the future. Due to its flexibility and energy storage characteristics after clustering, electric vehicles have a strong potential for demand response in the grid, and can realize two-way interaction between electric vehicles and the grid (Vehicle to Grid, V2G). Under reasonable scheduling, it can It can help the power grid to alleviate the power load, cut peaks and fill valleys, and can also provide auxiliary services such as frequency regulation and backup for the power grid. How to formulate a reasonable scheduling strategy is a key point in the...
