An MPC Approach for Grid-Forming Inverters: Theory and Experiment [PDF]
Energies, 2020 Microgrids (MGs) interest is growing very fast due to the environment urgency and their capability to integrate renewable energy in a flexible way. In particular, islanded MGs in which distributed energy resources (DERs) are connected to the infrastructure with power electronic converters have attracted the interest of many researchers of both academia

Adaptive Fault Detection for Grid-Forming Inverters
IEEE AccessThis work introduces a residual-based adaptive threshold for detecting faults in grid-forming inverters in AC microgrids islanded from the main grid. The inverters are modeled as a nonlinear system with one-sided Lipschitz nonlinearities and modeling uncertainties.

Coordinated Frequency and Voltage Regulation of Grid-Following and Grid-Forming Inverters
CoRR, 2020 In a purely inverter-based microgrid, both grid-forming (GFM) and grid-following (GFL) inverters will have a crucial role to play in frequency/voltage regulation and maintaining power sharing through their grid support capabilities. Consequently, the coordination between these two technologies becomes increasingly important for optimal system ...

Nonlinear Modeling and Identification of Doubly Fed Induction Machines Under Varying Grid Conditions
IEEE Open Journal of the Industrial Electronics SocietyHistorically, grid-connected synchronous machines have formed the grid voltage and frequency. Today, the high penetration of inverter-based resources poses challenges to grid stability, as conventional grid-following control methods do not provide grid ...
