Simultaneous stabilisation approach for power system damping control design through TCPAR employing global signals
journal contribution

regulator using global signals is proposed based on the simultaneous stabilisation approach. The
numerical design algorithm determines the controller parameters in order to guarantee closed-loop
poles in the left half plane with preferential treatment to those corresponding to the inter-area
modes. Plant models under different operating conditions are incorporated in the design
formulation to achieve the desired performance robustness. A three-input/single-output controller
is designed for the TCPAR to provide adequate damping to the critical inter-area modes of a study
system model. Based on the observability of the inter-area modes,real power flows from remote
locations are used as feedback stabilising signals. The damping performance of the controller is
examined in the frequency and time domains and is found to be robust against varying power-flow
patterns,n ature of loads,tie-line strengths and system non-linearities,including saturation.
