Distributed Network Reconfiguration Scheme with Self-healing for Distribution Network

Abstract

Distribution network reconfiguration is essential for safe operation under a high proportion of renewable energy. This paper proposes an online rolling optimization framework of distributed distribution network reconfiguration. Distributed consensus protocol is used to obtain the whole network topology and node operation information. The distribution network has a self-healing function under the proposed distribution network reconfiguration method, which can realize economic operation under normal operation state, and achieve automatic reconfiguration and self-healing under N-1 and N-2 line fault states without additional external trigger signals. To cope with the fluctuation of the high proportion of renewable energy, this paper adopts the look-ahead rolling optimization and uses the combination of the generated data and historical data of generative adversarial network as the basis for prediction. The simulation results on the IEEE 33-bus system show that the proposed method can automatically realize economic operation optimization and self-healing in normal state, single point fault, and two-point fault.
