Adaptive coordinated passivation control for generator excitation and thyristor controlled series compensation system

The problem of transient stability for a single machine infinite bus system with the generator excitation and thyristor controlled series compensation (TCSC) is addressed via the coordinated passivation method. The system does not need to be linearized. Two types of uncertainties, namely, the damping coefficient uncertainty and the modeling error of TCSC, are considered. First, an excitation control input and a parameter updating law are obtained simultaneously via adaptive back-stepping and Lyapunov methods to achieve stability of the zero dynamics subsystem. Then, a reactance modulated input is derived to ensure the feedback passivity of the whole system, based on which a stabilizing controller for the closed-loop system is designed. Simulation results show that the proposed controller produces better transient performance than the conventional direct feedback linearization controller.
