A novel random fuzzy P-Q-V voltage stability security region of power system interconnected with double-fed induction generator high penetration is discussed in the paper. Based on random fuzzy simulation, a novel random fuzzy continuation power flow (RFCPF) method is presented. The RFCPF method contains 2 aspects: Firstly, the double-fed induction generator steady equations are embedded in continuation power flow; secondly, the revised continuation power flow is used to process random fuzzy simulation to obtain the voltage critical points. By using RFCPF method, random fuzzy P-Q-V voltage sta...
