Distribution Network Power Supply Recovery Strategy after Disaster：Based on Path Description
The construction of the distribution network is weak in disaster prevention, which leads to component failure and loss of power in non-fault areas. In this paper, in order to restore the power supply as much as possible, the switch brake of distribution network is reorganized to change distribution network’s operation mode. In this method, the topology of distribution network is firstly modeled by path description method. And then, all the possible power supply paths are searched in the distribution network model by depth priority algorithm. Based on the principle of "ensure all critical loads to restore power supply and as far as possible to restore all non-critical loads", the optimi-zation equations are established to solve the post-disaster reconstruction topology and power supply recovery strategy of the distribution network. In the process of solving the problem of power supply strategy for power sup-ply recovery after disaster, the possible topology of power distribution network and critical load factors are fully considered in this paper. The strategy proposed in this paper can restore all the critical loads for the massive power outage after a disaster. In contrast to two typical algorithms, our method has a certain advantage.
