Optimal Operation for Resilient and Economic Modes in an Islanded Alaskan Grid
Legacy energy management systems for distribution system or microgrids are typically driven by economics. During extreme events, resiliency can be defined as ability of the system to keep supplying critical loads. Resilient operation during extreme events (e.g. avalanche in Alaska...

Autonomous Microgrid Restoration Using Grid-Forming Inverters and Smart Circuit Breakers
The proliferation of distributed inverter-based resources (IBRs) raises the questions if these IBRs can be used to blackstart microgrids and distribution feeders after major outages. In this paper, we propose and evaluate an autonomous microgrid restoration concept using grid-for...

Power-Hardware-in-the-Loop Interfaces for Inverter-Based Microgrid Experiments Including Transitions
Microgrids continue to proliferate, particularly those that rely on inverter-based resources as the microgrid's voltage and frequency leader. Hardware-in-the-loop simulations can de-risk microgrid deployments, and therefore we need power hardware-in-the-loop (PHIL) interfaces for ...
