| Abstract: | The field of Power systems bifurcation control (PSBC) is explored, the discrimination theory and control methods for the steady state bifurcations, i.e., saddle node bifurcation, transcritical bifurcation and pitchfork bifurcation, which are closely related to voltage unstability, voltage collapse, angle unstability and low frequency oscillation, are introduced and their theoretical base and algorithm system are analyzed, so the theoretical basis of how to effectively control these bifurcation phenomena to ensure the power system to operate securely and economically is provided. Finally, the concrete operating procedures of power system bifurcation control and stability analysis method for closed-loop control system are stated by a typical system. |
