Distributed Energy Resources Design Method to Improve Energy Security in Critical Facilities

This paper compares the performance of different control strategies for a single-phase inverter interfacing a distributed energy resource during abnormal transients or failures of the utility electric power system voltage. The performance of the various control methods is presented and compared to IEEE Standard 1547-2018 using a physicsbased model. The simulation scenarios are created to compare the controller responses to the intentional island and ridethrough recommended timing specified in IEEE Standard 15472018. The physics-based model is validated by experimental measurements on a laboratory prototype with a Field Programmable Gate Array based controller
