Decentralized coordination for mutual rescue in microgrid clusters

Microgrid (MG) clusters are small power systems that can help improve the resilience and flexibility of larger systems. In this work, we focus on designing an agent-based decentralized coordination method that healthy MGs to help unhealthy ones (e.g., in the case of insufficient generation). Coordination is expected to eliminate the power imbalance inside MGs, thus limiting the impact for customers and maximizing local generation. Decentralized coordination is especially useful as the resulting system is not subject to single points-of-failure. To ensure the feasibility of the power dispatch resulting from agents interaction, a distributed power flow calculation is used and enables verifying line capacity constraints. The operation of the system is tested with a system including 12 MGs and 33 MGs.
