Microgrids Resilience: Definition, Measures, and Algorithms

As distributed resource island systems, microgrids provide flexible and effective ways to maintain or restore power supply after an extreme event and enhance power system resilience. This chapter introduces the resilience-oriented measures associated with microgrids in the planning, preparation, and restoration stages. In the planning stages, allocating distributed energy resources like DGs and hardening infrastructures are important measures to promote flexible adaptation and resistance of microgrids to disasters. In the preparation stage, mobile emergency resource prepositioning and proactive operation measures can be carried out for quick response and damage mitigation. In the restoration stage, interconnecting multiple microgrids and even forming microgrids by dynamically adjusting the topology of distribution networks can efficiently leverage energy resources to improve load restoration capacity.
