Adjustable-frequency drives have been billed as an energy efficient way to drive three-phase ac induction motors. Nevertheless, designers should understand that motors fed by inverter power experience ...

Abstract: In grid-connected inverter (GCI), the asymmetrical control structures lead to frequency coupling effect, complicating system analysis and threatening grid stability. To suppress frequency ...

Abstract: To effectively supervise and regulate the frequency support strength of power systems with high penetrated inverter-based resources (IBRs), this paper proposes a novel minimum frequency ...
