The paper concerns with the implementation and optimization of secondary controller and tie-line controller to stabilize the frequency and tie-line oscillations in an interconnected deregulated power system using Evolutionary Hybrid Genetic Firefly algorithm. In the context a fractional order controller is used as a secondary controller and a thyristor controlled phase angle regulator is used as a tie-line controller to control the LFC dynamics. The control strategy was implemented on a composite deregulated power system spanned as a three area interconnected power system. The control parameters were optimized using hybrid genetic-firefly algorithm using area control error (ACE) as a fitness function to minimize. The simulation results depicts that the implementation of TCPAR along with fractional controller contributes in controlling wide range of LFC dynamics.
