Grid fault recovery and resilience: Applying Structured Energy and microgrids
William Cox, Toby Considine · 2014
We show how transactive techniques and Structured Energy address fault containment, resilience, and recovery. By applying the structured energy description of a grid as a topology of microgrids, including nesting, union, and intersection, we demonstrate a new way to understand fault resilience, containment, and recovery. Factoring operations management into microgrid management and cross-microgrid management reduces the complexity of each. We show how structured energy enables flexible changes in configuration as energy needs and supplies evolve, fail, and are restored, thus improving resilience in the face of failures. We suggest architectural approaches to grid configuration to improve fault resilience, including following geographic distribution of energy resources with distributed and transactive operation of those resources.
