摘要：This article proposes a nonlinear robust control design for Static Synchronous Compensator (STATCOM) to improve stability and oscillation damping of power system. Considering the parameter deviations, external disturbances and unmodeled dynamics, the nonlinear dynamic model of STATCOM can be translated into a Hamiltonian structure by means of coordinate transformation. Based on the Hamiltonian structure of STATCOM, a nonlinear robust (NR) control is designed for STATCOM. Numerical simulation results on the two-area four-machine power system demonstrate the robustness and effectiveness of the proposed NR control in comparison with the feedback linearization (FL) control. The comparative study results indicate that the NR control has better performance than the FL control.
