要約(日本語)：Previous studies have reported that virtual inertia control using grid-following (GFL) inverters can lead to system instability in power systems with low short-circuit capacity. Although adding a low-pass filter can stabilize the system, its effect on the inertial response speed has not been investigated. This paper experimentally verifies that a df/dt-type GFLinverter equipped with a low-pass filter can operate stably even in power systems with low short-circuit capacity. Furthermore, it compares the speed of the inertial response with that of a frequency-droop-type grid-forming (GFM) inverter under the same control parameters. The experimental results demonstrate that the GFL inverter can achieve aninertial response speed comparable to that of the GFM inverter.
