Abstract

The frequent occurrence of natural disasters and man-made attacks greatly increases the failure rate of urban integrated energy system in the face of such uncertain events, which seriously threatens the security and reliability of urban energy supply. Aiming at the resilience of urban electricity-gas integrated energy system under extreme events, a three-stage robust optimization model is proposed. The model aims to minimize the load shedding of integrated energy system under extreme events. The line fault fuzzy set is constructed through the component fault probability interval under extreme events, and the defense-attack-defense three-layer framework is established, then C&CG algorithm decomposes it into outer main problem and inner sub problem for solution. Finally, the effectiveness of the proposed method is verified by the improved IEEE-30 bus power system and 7-bus natural gas system.
