METHOD AND SYSTEM FOR ENHANCING TRANSIENT STABILITY OF POWER SYSTEM WITH RENEWABLE ENERGY

A method for enhancing transient stability of a renewable energy power system is performed as follows. An external subsystem corresponding to the renewable energy power system is constructed. A first matrix corresponding to the external subsystem based on voltage control is constructed. A second matrix corresponding to the renewable energy power system is generated. A transient stability Lyapunov function corresponding to the renewable energy power system is constructed in real time based on the first matrix and the second matrix. A first control signal corresponding to the renewable energy power system is generated based on Lyapunov's second method. The transient stability of the renewable energy power system is controlled and enhanced in real time based on the first control signal. The first control signal is an adaptive voltage control signal of the renewable energy power system.
