Abstract:

For oceanic island clusters with special geographical conditions, this paper proposes a rescue vessel scheduling strategy that integrates island transportation and energy supply to address resource heterogeneity among oceanic island clusters and ensure vessel safety, thereby improving the disaster resilience of rescue vessels under optimized scheduling. Based on both energy dispatch and transportation, a two-stage optimization method is adopted. In the first stage, day-ahead scheduling is performed according to the geographical relationship of the islands to determine preliminary sailing routes. In the second stage, both safe and emergency modes are considered. In the safe mode, based on the optimized routing information from the first stage, further optimal scheduling of power generation is performed to improve operational efficiency and economic performance under environmental constraints. In the emergency mode, considering generator fault, a coordinated optimization strategy between load-side management and power generation is implemented to support critical rigid loads and guarantee the normal operation of rescue vessels. Finally, simulation results verify the effectiveness of the proposed strategy, providing a theoretical reference for the sustainable development and construction of oceanic island clusters.
