Abstract :
In this research work, to empower more sophisticated control design, a new approach to build a nonlinear dynamic model of the power system is introduced. The proposed advancement is a complementary scheme of solving the differential-algebraic equations; for which achieving the control design has always been a challenge. For the proposed work an adaptive technique is used to derive the control signal. A back stepping methodology for the UPFC is used to mitigate the generator oscillations developing from perturbation like three-phase short circuit to ground fault. Simulation results on multi-area power systems illustrate the effectiveness of the suggested method.
