AI Technical Summary

Technical Problem

Existing methods for post-disaster recovery of power distribution networks fail to effectively utilize limited resources for system recovery and neglect the balance between economic efficiency and load loss.

Method used

Establish a pre-disaster EV scheduling model and the deployment location of mobile energy storage temporary warehouses. Combine this with electric vehicle V2G to construct a post-disaster resilient distribution network economic recovery model and optimize resource scheduling to reduce system power loss and scheduling costs.

Benefits of technology

When rapidly restoring the power distribution network after a disaster, by comprehensively considering the economics of mobile energy storage and V2G electric vehicles, the system power loss can be reduced and dispatch costs can be saved, thereby improving the economy and reliability of post-disaster recovery.

Abstract

This invention discloses a resilient distribution network recovery decision-making method and system. It establishes a pre-disaster EV dispatch model; determines the deployment location of temporary mobile energy storage warehouses based on distribution network line layout and load information; establishes a pre-disaster mobile resource pre-deployment model to ensure faster post-disaster load recovery while saving mobile resource operating costs; determines the configuration results based on the pre-disaster mobile resource pre-deployment model; constructs an economical post-disaster recovery model for resilient distribution networks that combines mobile energy storage and electric vehicle (V2G) as the objective function; and obtains the deployment location and quantity of mobile resources based on the post-disaster mobile energy storage and V2G collaborative recovery model to achieve post-disaster distribution network recovery. This invention can propose practical and effective power supply recovery solutions for different scenarios, guiding actual power systems to quickly restore system power supply while ensuring dispatch economy.
