In this paper a new approach is taken to solve the stability problem in the power system with the help of Flexible AC Transmission System (FACTS) devices and Tilt Integral Derivative (TID) controller. The FACTS devices can enhance the power system capability of transmission. A number of FACTS devices are working in the power system. Among these FACTS devices, Static VAR Compensator (SVC) is a shunt connected FACTS device which can be used effectively in Voltage Control mode. In the MATLAB power system model, SVC is operating with a PI controller, which has simple functioning and is cheaper in operation but has poor performance with non-linear characteristics. So to overcome this problem the controller is designed as a combination of both TID controller and Fuzzy Logic controller. TID controller has a tilted component, which replaces the proportional component in the PID controller. In this paper the suggested controller has been tested on a 2 machine 3 bus power system using MATLAB/SIMULINK software. The simulation consumes lesser run time and there are fewer oscillations in the system with the hybrid TID and Fuzzy Logic controller.

The wide-area coordinating control concept has gained rapid interest in power system control. It now offers substantial potential and great challenge to the power industry. This article proposes a new control design method based on widearea measurements to coordinate generator excitations and static VAR compensator auxiliary controls. A state space model of a multi-machine power system that includes a static VAR compensator is derived first. This model clearly shows the interactions between a static VAR compensator and generator variables. Next, remote measurements are used to generate coordinating signals for the static VAR compensator controller and the generator excitations. Two different control strategies are proposed. The first controller decouples the system dynamics by compensating the interaction terms between the static VAR compensator and generator variables. The second controller utilizes the relative gain array concept to evaluate the interactions. Only signals that contribute to the strongest interactions are used by the controller to reduce the interactions between the system components considerably. The second controller with a reduced set of measurements is compared to the first controller with full measurements. Results show that performances of both controllers are very similar. They provide significant additional damping for both local and inter-area oscillations. Communication time-delay effects are also considered in this study.
