Abstract

Static Series Synchronous Compensator (SSSC) is one of the controllable reactive power series compensators, which is applied to modify the power flow in the transmission line and enhance the electrical grid's small-signal stability. In this paper, a novel damping controller for the electrical network equipped with SSSC is presented considering H∞ control theory and Teaching Learning Based Optimization (TLBO) algorithm based on a fixed structure control scheme to reduce the controller order and minimize the system error. The suggested mechanism guarantees both meet the robustness criteria and move the undamped and lightly damped nodes toward the specified stability region. Therefore, a fixed structure controller is employed and designed by proposing a novel optimization problem. Moreover, SMIB connected to the SSSC system is applied to analyze the electrical network's small-signal stability. Finally, the proposed controller performance is compared to other conventional robust control methods and the simulation results show the controller achieves both excellent damping and acceptable robust performance compared to other methods.
