Abstract

Voltage stability is considered as one of the key concerns of hybrid AC/DC power grids, the mechanism of which can be quite complicated and involves multiple factors. This chapter provides a comprehensive overview on the concepts, and main causes and analysis methods of two voltage stability issues including the large-disturbance and small-disturbance voltage stability of the hybrid AC/DC power grids. The small-disturbance voltage stability analysis covering both the AC and DC system-oriented issues and relevant control measures are introduced, with the emphasis mainly on the operational equilibrium associated small-disturbance voltage stability issue solved by voltage sensitivity factor method and maximum power curve method. The influence of various uncertainties resulting from the high penetration of renewable power generation on the voltage stability of the hybrid AC/DC power grids is effectively investigated by using the probabilistic voltage stability analysis and associated variance indices in this chapter.
