Abstract :
This paper presents a systematic design procedure based on the H ∞ optimization technique for tuning robust damping controllers of power system thyristor controlled series compensation (TCSC) for a wide range of operating conditions. A new mixed model-matching robustness formulation is used in the design. The model-matching part requires a nominal damping controller, and the robustness part allows for the tuning of the controller. The formulation simplifies the selection of weights for tuning the controller. The procedure is used to design TCSC controllers to enhance the local mode damping in a single-machine power system and the inter-area mode damping in a 2-area 4-machine power system
