Resilience Planning Model of Flexible Resources Collaborative under Typhoon Disaster

Aiming at the problems brought by typhoon disaster to the safe operation of power system, this paper puts forward a cooperative resilience planning model of multiple flexible resources under typhoon disaster. Firstly, the failure rate of each branch is obtained according to the typhoon disaster disturbance and line failure rate model, and the information entropy method is used to identify the vulnerable lines. Then, flexible resources such as wind power, photovoltaic energy storage and line reinforcement are used to coordinate planning to improve system resilience. A two-stage three-layer defense-attack-defense model is constructed considering system economy and resilience, and the Column and Constraint Generation (C&CG) algorithm is used to solve the model. Finally, the effectiveness of the proposed model is verified by the IEEE30-node system.
