A hybrid method for identifying limit induced bifurcation point and saddle node bifurcation point in two stages is proposed， which is based on continuous power flow（CPF） method and point of collapse（PoC） method. The proposed method in this paper combines the advantages of CPF method and PoC method， and can consider power limits of all the generators in a power system， especially the power limit of the slack one. At the first stage， by using a conventional CPF method， it can go through the collapse point quickly by a large step. At the second stage， different methods can be used to identify and compute the collapse point accurately through analysis and comparison. The effectiveness of this method for analyzing the steady-state voltage collapse point and considering the power limit of the slack generator in the CPF computation are demonstrated through numerical results for IEEE 118-bus and 300-bus test systems.
