TCSC tuning via Ant Colony Optimization for power system stability improvement

This paper presents the problem of analysis and improvement of transient stability of power systems by the Ant Colony Optimization. Our work has focused on the design of a TCSC (Thyristor Controlled Series Compensator) installed in SMIB (single Machine Infinit Bus). The nonlinear analysis is performed to confirm the robustness of the TCSC tuned by such technique.
