Research on fault recovery and reconfiguration scheme of distributed generation distribution network

In case of failure in the distribution network area, considering the safety and stability of system operation, priority should be given to the reconstruction based on switch on-off to completely restore the power loss load. In this context, considering the economy of distribution network fault recovery, firstly, the distribution network fault recovery reconstruction model is established with minimizing network loss as the objective function. Then, the differential evolution algorithm based on natural number coding is used to improve the mutation strategy of complex distribution network coding in order to better solve the model. Finally, the applicability of this method is verified by ieee33 node simulation.
