This paper proposes a communication-assisted fault localization, isolation, and restoration method for microgrids based on a multi-agent system. The proposed system comprises distributed agents, located in the middle and at the two ends of a protection section, which will detect a fault through phase angle comparison of current signals at both sides of a given distribution line. The agents then send...
Migrating to a smart grid requires a paradigm shift in the implementation of power system applications. With the advent of IEC 61850, contemporary Substation Automation Systems (SAS) are utilizing electronic instrument transformers and merging units to transmit current and voltage measurements over Ethernet as Sampled Measured Values (SMV). However, if a substation's network resources are not properly...
This paper proposes a fault localization, isolation and restoration method for microgrids based on multiagent system (MAS) utilizing a communication network. The agents are located in the middle and the two ends of each section. The fault is detected through phase angle comparison of current signals at both sides of the distribution line and sends the trip signal to circuit breakers. This technique...
