A power supply restoration method of distribution network based on NSGA-II algorithm

With the rapid development of today's economy and society, people put forward higher requirements for power quality. In the process of distribution network operation, if there is a fault, it will produce immeasurable loss. It is necessary to restore the power supply in the non-fault power outage area in time. Therefore, it is particularly important to restore the power supply of distribution network quickly and efficiently. This paper considers factors such as load recovery, switching operation times and network loss. Based on the mathematical model of distribution network restoration and reconstruction, a genetic algorithm for distribution network power supply restoration and reconstruction is proposed. Combined with the characteristics of distribution network, the crossover rate and mutation rate suitable for distribution network are selected to improve the efficiency of the algorithm and make it quickly converge to the global optimal solution. Finally, the feasibility of distribution network is verified by an example.
