Title:
CHECKING METHOD AND SYSTEM FOR MEDIUM-AND-LONG-TERM MAINTENANCE PLAN IN POWER GRID, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/088890
Kind Code:
A1
Abstract:
A checking method and system for a medium-and-long-term maintenance plan in a power grid, and a device and a storage medium. The method comprises: obtaining a predicted load value and historical load values of a power grid (S1); clustering the predicted load value and the historical load values by means of a clustering algorithm, and selecting the historical moment of the historical load value that is of the same category as the predicted load value and has a maximum load value as a target historical moment (S2); obtaining a power grid operation mode model at the target historical moment, and updating the power grid operation mode model according to a maintenance plan and open-loop point information by using a full-wiring method, to obtain a future-state power grid operation mode model (S3); and calculating ground-state power flow data of the power grid on the basis of the future-state power grid operation mode model, and performing safety check of a medium-and-long-term maintenance plan in the power grid according to a preset ground-state power flow limit (S4).
