Enhancing Resilience of Distributed Resource Coordinated Configuration in Distribution Networks Under Typhoon Disaster

ObjectivesWith the increase of electrical equipment and frequent natural disasters, the demand for distribution network resilience is increasing. Therefore, a strategy of optimizing distributed resource cooperative allocation based on typhoon disaster is proposed.MethodsFirst of all, the power supply recovery potential of electric vehicle users participating in typhoon disasters is fully considered, and the power grid failure and electric vehicle pre-disaster scheduling model under typhoon disaster is constructed. Then, aiming at the lowest load loss cost and network fault risk cost, the optimal allocation model of distributed new energy is established. Finally, taking IEEE 33 node system as an example, three scenarios are set up for comparative study.ResultsThe comparative analysis results of the three scenarios show that the proposed strategy can achieve the lowest weighted comprehensive value of load loss and sum of branch cumulative over-limit power. Among them, the percentage of load loss reduction is 95.53%, and the reduction rate of the sum of branch cumulative over-limit power is 29.23%.ConclusionsIn the case of typhoon disaster, the proposed strategy can effectively restore the system load loss, improve the elasticity of the power grid, and reduce the operation risk of the system.
