Microgrid Clusters

Microgrid Clusters with Adaptive Decentralized Energy Management Towards Resilient Power Systems

Microgrids, as individual controllable units of power generation, storage, and consumption, have emerged as a promising solution to improving reliability and resilience to disturbance. When networked together in a self-adaptive manner, a cluster of microgrids can significantly enhance the reliability of power supply in a cooperative manner. With this insight, we explore the self-adaptive and decentralized energy management of a microgrid cluster considering the variations in wind and solar resources, as well as disturbances.

As a case study, a microgrid energy management scheme is proposed, by taking into account distributed energy storage responsive to the nodal prices throughout the cluster. The presented method comprises the ex-ante optimal dispatch to minimize the anticipated operation cost, followed by a near real-time dispatch to manage the violation of security constraints regarding any branch limit and voltage limit in the microgrid cluster. The second dispatch, as recourse to the ex-ante dispatch, aims to minimize the operation cost and the deviation from the ex-ante dispatch decisions, while any possible binding constraint occurred in the ex-ante dispatch is mitigated. Simulation results on a test microgrid system demonstrate that the presented scheme can effectively ensure secure and economic operations of the microgrid cluster as well as the risk reduction of the ex-ante decisions.
