The algorithm of power flow multiple solutions is a key approach for the research of voltage stability problem. First, the relationship between power flow multiple solutions and voltage stability was introduced together with its theo- retical basis, and the methods to estimate the number of power flow solutions were discussed. Then, the algorithms to solve all the solutions and Type 1 solutions were elaborated respectively, including homotopy method, Groebner basis method, Wu＇ s elimination method, optimal multiplier method and state space search method. Moreover, the realiza- tion processes and features of these algorithms were analyzed. Finally, the power flow multiple solutions was summarized, and the aspects that should be paid attention to in future studies were proposed.
