Double-layer Planning for Pelagic Island Microgrid Group Considering Typhoon Weather Effects

To address the issue of inflexibility in responding to typhoon weather conditions in the pelagic island microgrid group, an optimal configuration model of energy, hydrogen, and freshwater energy resource packages was constructed based on regular scenarios, typhoon scenarios, and typhoon early warning scenarios, and transported via energy storage ships. By integrating long-term planning decisions with short-term operational scheduling based on actual operational conditions, a double-layer planning model for microgrid clusters on islands is established. A double-layer planning model for the island microgrid group was established. The upper layer aimed to minimize investment and operating costs, while the lower layer focused on operational modeling to minimize operating costs, gas turbine output compensation costs, and maximize energy storage under typhoon warning scenarios. The C & CG algorithm is finally used to solve the operation layer and the reconfigured planning layer iteratively to realize the fast solution of the double-layer planning model. The simulation results indicate that considering the optimal configuration of energy resource packages leads to a decrease in the overall system cost and a reduction in wind and solar power curtailment.
