Abstract
A transient damping method (TDM), introducing the frequency of a virtual synchronous generator (VSG) through a high-pass filter (HPF) to the power reference, is usually adopted to stabilize the system against disturbances. However, different from a small-signal stability perspective, this letter reveals that the gain of HPF should not be too large due to the transient stability issues. Thus, an optimal parameter design method of the TDM is proposed for the improvement of transient stability. The experimental results validate the theoretical findings.
