Abstract:
... This paper proposes a peer-to-peer (P2P) energy bartering framework for enhancing resilience response of networked microgrids (NMGs) against extreme events. In the emergencies, electrically isolated microgrids (MGs) are physically interconnected via a common bus to form NMGs for energy sharing. These MGs communicate with each other through cyber links to reach a consensus on direct energy barterin ...
