DER and Microgrids Can Help with Black Start
DER and microgrids can also assist with the black start process, which is the process of restarting the power grid after a widespread blackout. During this process, many power generators may require external battery start-up. To achieve this, utilities develop black start plans, where smaller generators start larger generators, gradually bringing generation back online. During this process, service restoration must be accurately timed to ensure continuous matching of generation and load. DER can be a valuable resource for black start by allowing communities with microgrids to independently initiate the process and provide the capacity needed to start larger generators.
