Integrated Synchronization Control of Grid-Forming Inverters for Smooth Microgrid Transition
This paper develops an integrated synchronization control technique for a grid-forming inverter operating within a microgrid that can improve the microgrid's transients during microgrid transition operation. This integrated synchronization control includes the disconnection synchr...

Using Energy Storage-Based Grid Forming Inverters for Operational Reserve in Hybrid Diesel Microgrids
Studies transient dynamics in a hybrid diesel microgrid during loss of wind generation and evaluates a transition from diesel spinning reserve to a battery energy storage system operating reserve using grid-forming inverters. Combines electromagnetic simulations with a power hardw...

Dispatching Grid-Forming Inverters in Grid-Connected and Islanded Mode
This paper explores the dispatchability of grid-forming (GFM) inverters in grid-connected and islanded mode. GFM inverters usually use droop control to automatically share power with other GFM sources (inverters and synchronous generators) and follow the change in the load demand;...

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 ...
