Research on Charging-Discharging Control Strategy of Electric Vehicles Considering Wind Power Consumption in Ubiquitous Power Internet of Things

Abstract

The charge and discharge load of electric vehicles can participate in the power regulation of power grid to a certain extent, so as to achieve the purpose of cutting peaks and filling valleys and reducing system power fluctuations. Especially for the power systems containing wind farms, electric vehicles can also serve as energy storage devices to increase the utilization of wind power and reduce the impact of wind power fluctuations on the power grid. The control strategy based on the ubiquitous power internet of things of charging-discharging of electric vehicles was studied. A mathematical model containing wind power connected to the grid and electric vehicle charging and discharging was established, and the particle swarm optimization algorithm was used to compare the adjustment effects of different the grid. The simulation results verify the applicability and numbers of electric vehicles after they were connected to effectiveness of electric vehicles participating in the grid adjustment.
