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...

Design Power Control Strategies of Grid-Forming Inverters for Microgrid Application
This paper develops and compares two control schemes in the application control layer of a non-phase-locked loop (non-PLL) grid-forming (GFM) inverter to gain insight and understanding into how the two schemes affect the dynamic responses of GFM inverters and the transition operat...

Evaluation of Optimal Net Load Management in Microgrids Using Hardware-in-the-Loop Simulation
This paper presents the performance evaluation of a net load management (NLM) engine that balances load and generation in an isolated community to power a critical facility after a grid interruption event (e.g., the loss of a large generation unit). This NLM engine is particularly...
