Static voltage stability analysis for multi-infeed HVDC systems based on multivariate regression

Abstract

Stability issues will arise with multiple HVDC links feeding an AC power network, among which voltage stability is of great significance. In this paper, the quantitative relationship is obtained between static voltage stability and the associated factors by using the multivariate regression analysis. The information aggregation approach is employed to derive independent variables for constructing a multivariate regression model. Simulation results on a five-infeed HVDC system verify the effectiveness of the method.
