Robust transient stabilizer for power systems with superconducting magnetic energy storage unit

In this paper, the authors establish a nonlinear model of a single machine-infinite bus power system with SMES, based on the Park's electric and mechanical equations, and derive its linearized model with the structural uncertainties caused by the sinusoidal nonlinearities. Moreover, they design a quadratic transient stabilizer for power system by using descriptor-type H/sub /spl infin// control theory. Simulation results from MATLAB/SIMULINK are shown.
