Multiagent-Based Distribution Automation Solution for Self-Healing Grids

A multiagent-based distribution automation solution is proposed to be used in the distribution of self-healing grids to solve the service restoration part of the Fault Location, Isolation and Service Restoration (FLISR) task. The solution reduces the grid topology to an undirected weighted graph and executes a distributed implementation of Prim´s minimum spanning tree algorithm to solve the problem. The solution is compliant with state-of-the-art standards within smart grids, including but not limited to IEC61850. To test the performance of the algorithm, a testbed is assembled consisting of a physical dc grid model and several Arduino microcontrollers and Raspberry Pi computers. The test results show that the proposed algorithm can handle complex FLISR scenarios.
