Stable material transportation is crucial for quickly restoring power systems after disasters. Drone-based material transportation can bypass the limitations of ground transportation and reduce transportation time. However, the current UAV flight trajectory distribution optimization model cannot meet the needs of emergency relief material distribution in mountainous areas after disasters. Having a sound emergency distribution plan can significantly speed up the recovery of your distribution system.稳定的物料运输对于灾后快速恢复电力系统至关重要。基于无人机的物料运输可以绕过地面运输的限制并减少运输时间。然而,目前的无人机飞行轨迹分布优化模型无法满足灾后山区应急救灾物资配送的需要。制定合理的应急配电计划可以显著加快配电系统的恢复速度。
