A scheduling method for coordinated optimization of wind power and large-scale electric vehicles

Abstract

The invention relates to a scheduling method for coordinated optimization of wind power and large-scale electric vehicles, comprising the following steps: 1) constructing a coordinated optimization scheduling model of wind power and large-scale electric vehicles; The smallest optimization model; 3) Decompose the main problem of robust unit combination considering wind power uncertainty into the main problem of robust unit combination and the check sub-problem of wind power uncertainty; 4) In the lower optimization model, make each moment The scheduling plan of the electric vehicle aggregator should be equal to the charging and discharging plan of the total electric vehicles under its jurisdiction, and the charging and discharging constraints of electric vehicles are given; 5) The subproblem of electric vehicle constraints receives the main problem of robust unit combination considering the uncertainty of wind power The optimized solution delivered; 6) Solve to obtain the scheduling scheme of wind power, electric vehicles, and thermal power. Compared with the prior art, the present invention has the advantages of rapidity, reliability, strong applicability, good optimization effect and the like.

Description

technical field [0001] The invention relates to the technical field of dispatching of wind farms and electric vehicles, in particular to a dispatching method for coordinated optimization of wind power and large-scale electric vehicles. Background technique [0002] Wind power is the fastest growing and most promising renewable energy, which has played an important role in alleviating the energy crisis, saving energy and reducing emissions. However, due to its randomness and intermittent nature, the grid-connection of large-scale wind power has brought many challenges to the operation of the power system, seriously affecting the safe and stable operation of the power system. In recent years, with the popularization of electric vehicles, new ideas have been provided to deal with the impact of large-scale wind power grid integration. In-depth research on the coordinated dispatch of wind power and electric vehicles is urgently needed. [0003] At present, in the research on how...

Problems solved by technology

In the literature, the convex analysis method is used to track the given load curve to solve the charging and discharging optimization of electric vehicles, but when this method is used for large-scale electric vehicles, its applicability will be affected

It can be seen that these methods only consider the coordination among electric vehicles, ignoring the coordination between electric vehicles and thermal power units and wind power; in addition, it is not applicable when there are a large number of electric vehicles
