Abstract

Power system stability classification has been upgraded by including the effect of increasing penetration of converter-interfaced generations. In the relevant categories that are detailedly described in Chapter 4, weak grid instability is the dominant cause of real-world voltage source converter (VSC) instability events which has reached almost 50%. The intricate VSC control system brings a great challenge to explicitly analyze the unstable interaction mechanism. Besides, based on the post-event analysis, almost any part of the control could induce this unstable interaction, which further hinders an explicit explanation of this weak grid instability. In this chapter, a comprehensive stability analysis will be conducted to explore all instability causes from the VSC control system when interacting with a weak grid. Accordingly, to avoid the further complication of control by adding abundant stabilization controls, a simple and effective tuning solution for each type of instability cause will be provided, which will work when even the weakest weak grid is connected such that the short-circuit ratio (SCR) = 1.
