Abstract:This electric vehicle charging congestion control mechanism learn results from ideas of "closed-loop feedback congestion control" and "banker's algorithm" used in computer network.In the charging process,if there is congestion,the system will send feedback to the controller.According to the system state and the principles of "banker's algorithm",the combination of charge pile is found,which makes the transformer load within its rating and overall time of full charge the shortest.Then,the power of each charging pile is resigned by the combination,and new status information is sent to the controller from a closed-loop feedback control.Finally,the experiments are carried out when a group of random states of charging piles are congested.Moreover,the algorithm quickly finds out the best combination of charging power before protection devices verify the feasibility of the mechanism.
