MATLAB/Simlink Based Power System Stabilizer with PID controller

Abstract

The power system network is coming more disturbed and its power transfer capacity reduces gradually. The disturbance is
mainly caused due to increase in number of load, losses in the transmission line. It is very difficult to control the stability of
such system. Researchers have been conducted in this field with aim of incorporating power electronics device with electric
power system. In the bulk power transmission system these problems can be overcomes with the help of power electronic
devices. In the large power system power electronic based controllers called as FACTS (Flexible Ac Transmission systems)
plays a vital role in controlling the stability. The main purpose of this paper is to compare various FACTS devices such as
SVC, TSCS, SSSC, STATCOM, UPFC, IPFC, and DPFC. The survey is conducted by placing various facts devices in the
power system.
