Power system resilience is defined as the ability of power grids to anticipate, withstand, adapt and recover from high-impact low-probability (HILP) events. There are long-term and short-term measures that system operators can apply to enhance resilience.
Long-term measures include infrastructure hardening and resilient planning, while short-term operational measures are applied in the pre-event, during-event and post-event phase. Microgrids (MGs) can effectively enhance resilience for both transmission and distribution systems, due to their ability to operate in a controlled, coordinated way, when connected to the main power grid and in islanded mode.
In this presentation, various real-world events, where MGs have been used to enhance power system resilience in various extreme weather events. MG-based operational measures for resilience enhancement will be presented, including the systematic MGs formation after natural disasters hit the system and MG-based resilient operational planning.
