Scheduling method and system for wind-network-station-vehicle system

Abstract

The invention discloses a scheduling method and system for a wind-network-station-vehicle system. The method comprises the following steps: acquiring information of a charging station and an electricvehicle supporting scheduling; performing charging time grouping and charging power grouping on the acquired information; calculating to obtain a probability function that the electric vehicle cannotbe charged according to prediction; taking the charging station as a revenue party, and establishing a target function of economic benefit maximization; establishing an objective function of social welfare maximization; establishing constraint conditions and performing uncertainty processing based on a credibility theory to obtain comprehensive constraint conditions of wind-network-station-vehiclesystem scheduling; and solving the comprehensive constraint condition to obtain an optimized scheduling result. By establishing a social welfare maximization objective function and establishing a constraint condition by taking the social welfare maximization objective function as an objective, optimal scheduling of a wind-network-station-vehicle system is realized, the situation of charging station congestion or charging station idleness is avoided, and the electric energy utilization rate of wind power generation is improved.

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 ...

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
