/Method Of Transient-free Transformer Energization And Black Start Using Inverter Based Resources
Abstract

Systems and methods for energizing transformers with inverter-based resources (IBRs) are provided. IBRs can pick up local critical loads after blackout and ultimately support the bulk power system recovery. The transformer energization process can be achieved by controlling IBRs without any inrush current, and the duration of the process can be instant or essentially instant.
