Abstract
This work presents a novel dual optimized controller to damp intra plant and inter area oscillations in power system. The parameters of controllers are tuned by a novel hybrid Differential Evolution-Grey Wolf Optimizer (DE-GWO). The dual optimized controller simultaneously controls two independent variables of UPFC there by maximizing the efficacy of controller and UPFC. The effectiveness of proposed algorithm is justified by testing with standard benchmark functions. The dual controller is applied to single and multi machine system for small signal stability assessment. A broad comparison is performed between single and dual controllers employing other standard algorithms prevailing in recent researches. Different objective functions are verified with this controller and ITAE was found to provide best response and selected here for minimization. The oscillation peaks, settling time and eigen values of system response show that proposed dual controller damps oscillations to a large extent in contrast to other single and dual optimized controllers.
