A bi-layer optimal strategy of electric vehicle and wind power collaborative access to the grid

This paper proposes a bi-layer optimization model of coordinated grid access of electric vehicles and wind power.The upper model aims to minimize the variance of load and the charging cost of electric vehicle when the electric vehicle and wind power access the grid,and obtains the combined load guidance curve of electric vehicle and wind power.The lower level model aims to minimize the deviation between the actual equivalent load and the load guidance curve of electric vehicle and wind power,and carries out real-time load following.In order to ensure the orderly charging and discharging of electric vehicles,this paper also puts forward the parameters of electric vehicles,including the comprehensive evaluation coefficient of users and the discharge influence factor,etc.,to divide the queues and prioritize the charging and discharging of electric vehicles.The simulation results show that the coordinated optimal scheduling of electric vehicles and wind power can not only reduce the impact of wind power prediction error,promote wind power consumption,but also increase the revenue of charging station operators,and achieve the purpose of cutting peak and filling valley.
