Experimental Characterization Test of a Grid-Forming Inverter for Microgrid Applications
Standardized experimental testing protocols for grid forming (GFM) inverters to ensure expected operation under both normal and contingency conditions do not exist. Such protocols increase the confidence of system owner/operators that an inverter deployed in a proposed system will...

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;...

Performance Evaluation of Peer-to-Peer Distributed Microgrids Coordination for Voltage Regulation
This paper presents the performance evaluation of a peer-to-peer microgrids coordination algorithm for sub-transmission systems. As distributed energy resources (DERs) in distribution system start to show negative impact to the bulk power system, a paradigm shift is needed for tra...
