Research on the Test and Verification Technology of ADN Fault Prevention for Multi-Flow Fusion

A great many the majority of distributed power sources, electric vehicle charging piles, energy storage, flexible interconnection equipment, new generation of distribution automation systems and terminals are connected to the distribution network, making the distribution network gradually transition from passive network to active network. At the same time, advanced information communication, control systems and ADN (ADN) are coupled, acting and influencing each other, making the distribution network evolve into an ADN with “energy - information - control - business” multi-stream integration. In multi-current fusion ADN, fault prevention is very important for fast fault location and power supply recovery. Firstly, the paper proposes a multi-scenario positive method for the ADN with multi-current fusion. Combining the basic and decisive functions of feeder automation in the ADN fault prevention, the paper tests and verifies the effectiveness of the ADN fault prevention strategy based on the simulation platform of the ADN with multi-current fusion. The effectiveness of the ADN fault prevention strategy is verified by analyzing the processing ability of the information communication effectiveness in the case of multiple faults in the ADN.
