Source-grid-load Coordinated Resilience Enhancement Model Considering Multi-type Contingency Uncertainty Under Typhoon Disaster
Considering the insufficient characterization of the uncertainty of component contingency and incoordination of source-grid-load in the existing resilience enhancement model,a resilience-oriented source-grid-load method considering the uncertainty of multi-types contingencies under typhoon disaster is proposed.Firstly,a component contingency uncertainty set is constructed to characterize the failure rate probability distribution uncertainty of multi-types of contingencies such as the most serious,the most likely,and the critical section cascade under typhoon disaster.Then,a distributionally robust model that incorporates both long and short-term,source-grid-load coordinated resilience enhancement measures is constructed:for the worst-case probability distribution of component contingency,transmission network expansion planning,unit commitment,and optimal transmission switching is carried out before the disaster,and the generator and differential load scheduling is performed to prevent and response to the contingency in typhoon disaster.Then,based on the mathematical structure of the model,a primal-dual parallel decomposition algorithm is designed to solve the model based on Bender's decomposition and column-and-constraint generation concepts.Finally,the effect of source-grid-load flexibility resources on transmission network resilience enhancement and the effectiveness of the proposed method is verified on the IEEE-30 bus and a Chinese 261 bus system.
