针对具有特殊地理条件的海洋岛屿集群，提出联合岛屿交通运输与能源供给的救援船调度策略，解决海洋岛屿集群资源差异性与救援船安全性保障的问题，提高优化调度下救援船的容灾能力。基于能量调度和交通两方面，采用两阶段优化方法。第一阶段：根据岛屿位置关系进行日前调度，预先制定航线。第二阶段计及安全模式与紧急模式：在安全模式下，根据第一阶段优化后的航线信息，进一步对系统进行发电优化调度，在环境约束条件下提高系统运行效率与经济性；在紧急模式下，计入发电机故障，采用负荷侧管理与发电协同优化调度方法，支撑系统的刚性负荷需求，保障救援船正常作业。最后，仿真结果验证了本文提出的策略有效性，为海洋岛屿群可持续发展与建设提供理论参考。

For oceanic island clusters with the special geographical conditions, this paper proposes a dispatching strategy for rescue ships, which combines island transportation and energy supply to solve the problems of the resource difference of oceanic island clusters, and the security guarantee of rescue ships. It can improve the disaster recovery ability of rescue ships under optimal scheduling. In terms of energy dispatch and transportation, a two-stage optimization method is adopted. The first stage is that the route can be set by the day-ahead scheduling according to the location of the island. The second stage considers the safe and emergency modes. In the safe mode, according to the route information optimized in the first stage, the system is furtherly optimized for power generation scheduling to improve the operation efficiency and economy of the system under environmental constraints. In the emergency mode, considering the generators’ fault, the load-side management and the collaborative optimization scheduling method for the power generation are adopted to support the rigid load demand of the system and guarantee the normal operation of rescue ships . Finally, the simulation results verify the effectiveness of the proposed strategy, which provides a theoretical reference for the sustainable development and construction of oceanic island clusters.
