Nonlinear coordinated control design of excitation and STATCOM of power systems

This paper presents a nonlinear control scheme for designing the coordinated STATCOM and excitation controllers to enhance the transient stability of power system. The STATCOM installed at the midpoint of the transmission line in a simple power system (a single machine connected to infinite bus). The zero dynamics design theory and pole-assignment technique is employed to design the nonlinear controller. The controller's performance in a SMIB system is also examined using simulation studies and the results validate the efficacy of the proposed controller.
