AI Technical Summary

Technical Problem

In existing technologies, the collaborative charging and discharging scheduling methods between charging pile groups and the cloud lack fine-grained correspondence, resulting in a lack of continuity in energy behavior switching, resource idleness or command conflicts, affecting the stability of revenue and increasing the operational pressure on the station.

Method used

By obtaining the vehicle's return time and next departure time, the continuous parking time segment is determined, and a V2G participation scheduling time slice sequence is generated. Combined with the power grid interaction interface information and vehicle status, a time slice charging and discharging interaction arrangement sequence is generated. Furthermore, fine-grained matching and task allocation between vehicles and charging piles are performed to generate a vehicle group charging and discharging scheduling instruction sequence and dynamically adjust for abnormal situations.

Benefits of technology

It enables precise matching of vehicles and charging stations, improves scheduling stability and energy coordination, enhances service fulfillment certainty, and reduces resource idleness and instruction conflicts.

Abstract

The present application relates to the technical field of charging and discharging scheduling, in particular to a charging pile group and cloud collaborative charging and discharging scheduling method and system supporting V2G, collecting back-to-site and vehicle departure time to generate V2G scheduling time slice sequence, formulating time slice charging and discharging arrangement in combination with electricity price and load information, demarcating vehicle charging and discharging participation range according to battery state and facility constraint, executing vehicle pile matching and task allocation based on energy flow direction and participation range, and generating charging and discharging scheduling results while responding to connection and operation changes to dynamically adjust instructions during execution. According to the present application, available scheduling units are locked according to back-to-site and vehicle departure time sequence, energy direction labels are established through power grid information mapping, participation sets are generated to screen feasible tasks by fusing vehicle state guarantee and station load boundary, a connection and plan change response mechanism is introduced in the execution stage to reorganize resources and correct instructions, and finally the scheduling stability and energy collaboration level are improved and the service realization certainty is enhanced.
