Inverter Controls for Smooth Transition Operation and Voltage Balancing of Networked Microgrids
With increasing penetrations of distributed energy resources (DERs), researchers have extensively studied the formation and networking of microgrids to improve reliability during distribution system outages. However, these operations might require DERs in the microgrids to switch...

Study of Seamless Microgrid Transition Operation Using Grid-Forming Inverters
This paper investigates operational techniques to achieve seamless (smooth) microgrid (MG) transitions by dispatching a grid-forming (GFM) inverter. In traditional approaches, the GFM inverter must switch between grid-following (GFL) and GFM control modes during MG transition oper...

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...
