Problems solved by technology

[0003] With the gradual increase of EV users, it is easy to appear at the same charging station, there are multiple EVs charging at the same time period, and EV users need to wait for the phenomenon, or at the same charging station, there are no EVs charging at the same time period, and charging occurs. The phenomenon that the station is idle, resulting in a low utilization rate of wind power

Abstract

The invention discloses a scheduling method and system for a wind-network-station-vehicle system. The method includes: obtaining information on charging stations and electric vehicles that support scheduling; grouping the obtained information on charging time and charging power; calculating the probability function that electric vehicles fail to charge according to predictions; using charging stations as beneficiaries, establishing The objective function of maximizing economic benefits; establishing the objective function of maximizing social welfare; establishing constraints and dealing with uncertainties based on credibility theory to obtain the comprehensive constraints of wind-network-station-vehicle system scheduling; The constraint conditions are solved, and the optimal scheduling result is obtained. By establishing the objective function of maximizing social welfare and establishing constraints based on the objective function of maximizing social welfare, the optimal scheduling of the wind-network-station-vehicle system can be realized, and the situation of charging station congestion or idle charging stations can be avoided. Improve the utilization rate of wind power.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a scheduling method and system for a wind-grid-station-vehicle system. Background technique [0002] The development and utilization of wind energy not only alleviates the energy crisis, reduces the discharge of pollutants, but also improves the economy of the power system. However, due to the randomness and volatility of wind power output, the phenomenon of wind curtailment continues to appear. In recent years, the continuous emergence of electric vehicles (electric vehicles, EVs) has brought about a turning point for this situation, forming a wind-network-station-vehicle system, that is, wind power generation components generate electricity and supply electric energy to the grid, and then The grid supplies electric energy to the charging station, and finally charges the electric vehicle at the charging station. [0003] With the gradual increase of EV users, it is easy ...
