A design method of nonlinear optimal predictive controller for thyristor controlled series compensation

摘要

In this paper, a design method of thyristor controlled series compensation (TCSC) controller with closed-form analytic solution control law is presented so as to improve transient stability and dynamic performance of power systems, on the basis of nonlinear optimal predictive control theory. The control scheme is robust and considers uncertainty of power systems. The stability of the closed-loop system is guaranteed by the control law which does not require on-line optimization and the huge calculation burden is avoided, besides, all input variables can be obtained locally. The simulation results demonstrate that the controller may improve transient stability and dynamic performance of power systems significantly.
