Enhancing Resilience by Outage Management Strategy Based on Semidefinite Programming Relaxation Method in Unbalanced Microgrids

•Proposing an outage management model based on a risk-averse strategy in an unbalanced MG,•Applying the proposed model to common contingencies in extreme weather events,•Convexifying non-convex proposed model via semi-definite programming,•Optimal scheduling of a low to moderate penetration level of dispatchable DERs,•Considering the demand response program as curtailed demands in the proposed model.
