摘要

Abstract

Virtual synchronous generators (VSGs) can provide voltage and frequency support to power systems due to their inertial and damping features. Unfortunately

power angle stability and fault current limitations are still challenging aspects of VSGs under large disturbances. Power angle stability and fault current limitations are indispensable for the safe operation of a VSG. However

in existing studies

these aspects are mostly solved as two independent problems. In this paper

the comprehensive transient stability enhancement (CTSE) control strategy for a VSG

considering power angle stability and fault current limitations is proposed. With a CTSE control

VSG's transient power angle stability is guaranteed. In addition

the steady-state and impulse components of the fault current are fully limited. Furthermore

CTSE control parameters adapted to different fault degrees are presented. Finally

simulation and experimental tests are performed to validate the performance of the proposed method.
