Abstract:

A coordinated optimal dispatch strategy of wind and photovoltaic generation and new energy vehicles was proposed for the problem， which is caused by large-scale new energy vehicles disorderly charging in power grid. Firstly， the model of new energy vehicles power battery was built， and a calculation method of charging load based on Monte Carlo method was proposed. Secondly， based on the principle of wind and photovoltaic power generation， the mathematical models of wind power generation and photovoltaic power generation were established. Finally， The objective function of the dispatch strategy is to minimize the standard deviation of the comprehensive load of the power grid， and the active set algorithm was utilized to solve the quadratic programming problem to obtain the coordinated optimal dispatch strategy. The simulation results show that the strategy can effectively avoid the aggravating difference between peak and valley load， which is caused by large-scale new energy vehicles disorderly charging in power grid.

Key words: new energy vehicle, power battery, wind and photovoltaic generation, coordinated optimal
