5G-Based Intelligent Distributed Feeder Automation Strategy for Distribution Network with DG

With the connection of Distributed Generations (DG) in distribution network, intelligent distributed feeder automation (IDFA) faces challenges of more sophisticated fault handling procedures and tighter deadlines. Unfortunately, the topology of distribution networks cannot be reliably identified using current techniques. In this work, this paper proposes an intelligent distributed feeder automation strategy for distribution network with DG based on 5G, with the capability of real-time topology automatic identification, and taking into account the technical benefits of low latency of 5G. The new essential topology information required for IDFA, named as fault-affected ports, is proposed for rapid power recovery. According to the above strategy, the PSCAD simulation model is built in this paper to verify the fault location and isolation strategy.
