Study of Inverter Control Strategies on the Stability of Low-Inertia Microgrid Systems
This paper investigates the stability of low-inertia microgrid systems with two control strategies that have different percentages of grid-forming (GFM) inverters. The first control strategy has approximately 50% GFM inverters, and all the battery inverters are working in GFM con...

Droop Control-Based Dispatch of an Islanded Microgrid with Multiple Grid-Forming Sources
Before rotating, fossil fuel-based, synchronous generators (SGs) are phased out, in line with renewable generation goals, grid-forming (GFM) inverters are expected to parallel SGs. Primary droop control allows GFM inverters to share power without communication; however, it is nece...
