Abstract
Inverter-based renewable energy resources, as a critical response to the net-zero energy transition, have been displacing conventional synchronous generation. However, this displacement has increased the grid's vulnerability to disturbances. The virtual synchronous generator (VSG) is a potential solution for grid strengthening. However, previous research has shown that VSG can also experience instability under certain grid conditions, which have been partially addressed in previous work. This paper aims to fill the gaps in these works by exploring the fundamental causation of instability through an updated comprehensive state-space modeling, parameter scanning, and consequent states participation factor analysis. It has been found that both voltage and active power controllers contribute to low-frequency instabilities in most cases. Furthermore, the two controllers are tightly coupled, although parameterising may improve decoupling.
