With synchronous generation fleets retiring and also with increase in extreme events, utilities and system planners have to make plans to ensure reliability of the system and ability to restore the system once an extreme event occurs. If there is a lot of sunshine and/or wind blowing, customers can ask why they do not have electricity. The presentation will discuss the capability of carrying out blackstart and system restoration from inverter based resources. Further, control interactions that can arise with multiple resources participating in blackstart will also be touched upon.
