The Impact of Three-phase Impedances on the Stability of DER Systems
The Impact of Three-phase Impedances on the Stability of DER Systems
In this work we explore impedance-based interactions that arise when inverter-connected distributed energy resources (DERs) inject real and reactive power to regulate voltage and power flows on three-phase unbalanced distribution grids. We consider two inverter control frameworks that compute power setpoints: a mix of volt/var and volt/watt control, and Phasor-Based …
