Abstract
This paper presents a comprehensive method combined with the techniques such as an improved predictor/corrector, second order index and dichotomy to predict the point of collapse (PoC) constrained by limit-induced bifurcation (LIB), saddle-node bifurcation (SNB) and security limit. Case studies with IEEE118-bus systems are carried out and accordingly final conclusions can be reached that the method introduced here balances in linearity, speed and accuracy. And it can present distinct advantages with reactive power information and is very suitable for online voltage stability assessment.
