Resilience -Oriented Generation-Grid-Storage Coordinated Planning of Power Grid under Typhoon

With the increasing frequency of typhoons each year, it has become necessary to plan for longer time scales that incorporate resilience enhancement for the power grid in coastal cities. Since typhoon paths and sizes are uncertain, planning solutions cannot be tailored to a specific typhoon. The construction of typhoon models that account for uncertainty in the future is the first challenge that must be addressed. This paper proposes a simulated typhoon model based on the Synthetic Minority Oversampling Technique(SMOTE) oversampling method, using historical transit typhoon data from a northern coastal city. The model fits a massive typhoon disaster scenario based on typhoon key parameter distribution functions. Then, a collaborative source-grid-storage planning method is established to enhance resilience under the typhoon model. This method plans for multiple types of power sources, grids, and energy storage, including conventional and new energy sources, to fully utilize the response characteristics of the power grid. This method also considers transmission grid reconstruction during special operation status. Finally, an actual grid of a coastal province in China is selected to verify the practicality of the method, which demonstrates that the method can balance the resilience and economy on a long-time scale.
