# Feedback Linearization Method for Improvement of Power Systems Transient Stability Mini Project Report

## Introduction to Feedback Linearization Method for Improvement of Power Systems Transient Stability Mini Project:

Any device cannot give 100 percent output from the given input. All the devices which we are using are cable of give two thirds of the supplied input as output. So we need to increase the output efficiency and there are various methods for improving the output efficiency of the device. By using these techniques we cannot get 100 percent output but we can get better maximized output. In this paper we will discuss feedback linearization method which is used for increasing the output stability of power systems.

Brief of feedback models:

In feedback method we will check the output of the device and based on the result we will make a feedback which improves its output efficiency. For controlling of nonlinear systems the feedback linearization method is best one. By using a certain control point we can convert the nonlinear systems into linear systems. We use linear control techniques and algebraic transformations for making the conversion from non linear to linear systems.

To model the power system we use a multi variable non linear controller. Multi variable non linear controller is designed based on the concept of feedback linearization which con improves the transient stability of the power systems and we can control voltage regulations even at fault conditions. The controller enhances the swing stability and damping occurring at larger disturbances which increases the terminal voltage regulation. In power systems the operating points change very frequently so by linearization method we can control the varying operating points.

Conclusions:

The feedback linearization method is the best one for improving the transient stability of the power systems and they can control the varying operating points through linearization which is not possible by conventional methods. This is the most efficient method for maximizing the output of the device. By using feedbacks we can control the output by using a controller and it can be varied by changing the input parameters.
