Abstract

Virtual synchronous generator control provides a potential solution to connect power electronics interfaced sources to the power system. With its flexible control, the emulated inertia may be adaptively changed to enhance system small-signal stability. However, previously proposed methods may have adverse impact to system transient stability. This paper proposes to improve the methods by using wide-area measurements, namely center of inertia frequency. Experimental results are presented to both demonstrate the limitations of previous control schemes, and the effectiveness of the proposed one. The practical implementation of this method is discussed.
