Virtual-Admittance Parameter Impact on Damping Provision from Grid-Forming Controlled Converters

Paper i proceeding, 2026

Grid-forming (GFM) converter control is a control approach to address several of the challenges associated with increased proliferation of power-electronic converters in electrical power grids. Virtual-admittance (VA) based GFM control structures allow to shape the converter’s frequency response, and control structures like the decoupled GFM controller enable the independent tuning of virtual resistance and virtual inductance. This raises the need for effective tuning methods covering the different aspects of converter performance that are influenced by the choice of VA parameters. This paper presents a simplified method to study the impact of VA parameters on the provision of passive damping from a GFM-controlled converter and compares
it to a power-response matrix-based analysis. The findings are verified using time-domain simulations.
