Abstract
The popularity of electric vehicles has become a trend, which will have a profound impact on the operation of the power system. Electric vehicle charging control is an important means of system operation control,It can not only limit the adverse impact of charging load, but also achieve peak load reduction and valley filling, promote the absorption of renewable energy, and play the role of load scheduling. With the large-scale development of electric vehicles, the rational charging problem of electric vehicles has not been solved very well. Aiming at the problem of charging and discharging power allocation on the user side of electric vehicles, analysis from the Perspective of Private Users of Electric Vehicles,Based on local energy management system and time-sharing pricing mechanism, proposed a control strategy of orderly charging and discharging power distribution for electric vehicles。According to the charge discharge power limit and charge and discharge price provided by the superior system, the incentive factor is introduced. By optimizing the charge and discharge power at each time period, the objective ordered charge discharge model is set up with the lowest total cost of the user. In the case analysis of only charging and discharging, the optimal solution is obtained by using the linear programming simplex algorithm, which provides an orderly charge and discharge scheme for the electric vehicle users.
