Power System Oscillation Damping with Adaptive Unified Power Flow Controller

In the family of FACTS devices The unified power flow controller is treated as a most powerful device which increase the transient stability of the system. a suggested controller is used here which can eliminate the disadvantages of the conventional controllers generally used in power system stability and give the better dynamic characteristics. The novel approach proposed here includes developing a non-linear dynamic approximation of the power network, using a unified power flow controller as a controller, augmenting the unified power flow controller with non-linear adaptive control based on back-stepping for oscillation damping, and using an adaptive control law to approximate uncertain parameters that contribute significantly to the stability of the power system. The feasibility of the proposed technique is validated using simulation on a single-machine to infinite-bus system.
