Abstract

The invention discloses a multi-objective optimization method of a disaster-resistant backbone network frame of a power system, belonging to the technical field of the power system, which proposes that three objectives of maximizing difference programming economy, system recoverability and network invulnerability are simultaneously taken as backbone network frame optimization objectives, and the backbone network frame needs to satisfy certain constraint conditions; a comprehensive learning particle swarm optimization algorithm is used to solve the multi-objective optimization problem of backbone network frame, and a graph theory repair strategy is embedded to repair the particles that do not meet the connectivity constraints. A multi-objective non-cooperative equilibrium method based on hybrid strategy Nash equilibrium is used to solve the optimal compromise solution of Pareto front solution as the optimal backbone grid scheme. The multi-objective optimization strategy provided by theinvention can provide a reasonable backbone network frame construction scheme for the differential planning of the power network, and can realize the balance of three objective functions of economy, system recoverability and network invulnerability.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a multi-objective optimization method for a disaster-resistant backbone network frame of a power system. Background technique [0002] Frequent extreme natural disasters seriously threaten the safe and reliable operation of power systems. Studies have shown that the root cause of blackouts caused by extreme natural disasters is that the existing fortification standards of power facilities cannot resist increasingly severe natural disasters. In addition, due to the different locations and importance of components such as substations, lines, and towers in the power system, it is necessary to design the disaster resistance of components in a differentiated manner before disasters come, according to the principle of "generally improving, focusing on strengthening". Standards, that is, to ensure the power supply needs of important power users by building disaster-resistant back...
