Title:
POWER GRID PARTITIONING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/202046
Kind Code:
A1
Abstract:
A power grid partitioning method, comprising acquiring a topological graph of an actual power grid structure; performing random partitioning on the topological graph of the actual power grid structure according to a set number of total partitions so as to obtain a particle swarm; then calculating a load loss risk value generated when the particle swarm suffers from an external attack under an extreme condition; by using an improved particle swarm optimization algorithm, with a goal of achieving that the load loss risk value generated when the particle swarm suffers from an external attack under the extreme condition is reduced and tends to be stable, continuously optimizing the particle swarm; and when the load loss risk value generated when the particle swarm suffers from an external attack under the extreme condition is reduced and tends to be stable, obtaining a power grid partitioning solution of the actual power grid structure. In the solution, by means of the power grid partitioning method, all partitions are separated, so that the survivability under an extreme condition of the power grid can be improved, a power failure range and a load loss can be reduced when the power grid suffers from an external attack, and continuous power supply for important users is ensured.
