Abstract
Grid-forming (GFM) voltage-source converter (VSC) systems mimic the inertial response of synchronous generators, though the inertial response time varies with the dynamic grid environment. This paper presents a comprehensive evaluation of the inertial response time in GFM VSC systems. It begins by defining the inertial response time for transient power support, followed by an analytical expression for the evaluation. The analysis reveals that the inertial response time is influenced by several factors, including the grid characteristics, grid interconnection levels, and specific VSC control settings. It also notes the occurrence of under-damped oscillations during grid condition changes. Simulation results validate the analysis of GFM-VSC inertial response time.
