Consider the fault recovery strategy of active distribution network for UAV recovery of temporary communication

Aiming at the problem of large-scale information blind spot load recovery caused by communication interruption, an active distribution network fault recovery strategy considering the temporary communication restoration of unmanned aerial vehicle (UAV) is proposed. Firstly, under the constraint of limited UAV resources, a rapid recovery model of the communication network with the goal of maximizing the high-priority load coverage of the blind zone is constructed, and the optimal deployment location of the UAV and the configuration scheme of emergency communication equipment required in each blind area are optimized. On this basis, by coordinating the dispatchable resources in the region, the isolated island division and network topology reconstruction are implemented simultaneously to realize the collaborative optimization of UAV deployment scheme and emergency repair scheduling, so as to maximize the amount of fault load recovery. Finally, the effectiveness and superiority of the proposed fault recovery strategy are verified by simulation experiments, and the complete recovery time of the proposed policy is shortened by 60% compared with the fault recovery strategy of manual communication network maintenance.
