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...
This research paper describes the automatic generation control of a three thermal interconnected system where each area is provided with a reheat thermal unit. The dynamic stability of this multi-area system is regulated by PD-PID cascaded controller optimized by grey wolf optimization algorithm. Each area is provided by proper generation rate constraints (GRC) in order to consider system nonlinearities...
This paper presents grey wolf optimization(GWO), which is a recently reported novel meta-heuristic optimizer, applied to optimize the damping controller parameters for a unified power flow controller connected to a single machine infinite bus power system for power oscillation damping.

In this research paper an optimal 2-Degree freedom of proportional-integral-derivative controller (2-DOF PID) tuned by grey wolf optimization(GWO) is suggested for automatic generation control (AGC) of a multi-source power system comprising of two areas where each area contains a thermal unit, a hydro unit and a gas unit. The active response of the system is observed under two cases: with AC tie-line...
This work proposes hybrid DE-PSO algorithm to tune the parameters of UPFC based lead-lag controller. Both DE and PSO are two powerful meta-heuristic optimization techniques with different special features. These specialities are combined together in hybrid DE-PSO algorithm. The parameters of UPFC based lead-lag controller are optimized by this hybrid DE-PSO algorithm by taking integral time absolute...
This paper proposes the design of an optimized dual UPFC controller for damping power system oscillations, where modulation index of series converter and phase angle of shunt converter voltage are controlled simultaneously. The dual damping controller parameters are optimized by a recently reported metaheuristic optimization technique known as Grey Wolf Optimizer (GWO). This is a simple technique...
This paper presents a nonlinear controller based on the fuzzy sliding-mode control technique to improve the transient stability of the power system. The rapid response of a controller is very desirable to damp transient power oscillation in the power system which is achieved with this control technique by shifting the sliding surface closer to the error trajectory using fuzzy logic. By this the sliding...
