Comparison of dynamic performances of TCSC, Statcom, SSSC on inter-area oscillations

Abstract

In power grid, the development of dynamic activity of power flow into grid represents a continuous challenge. This challenge is to transfer power in a full capacity and reduces power losses to minimum range. This lead to a necessity of studying the problems that affect on power system stability for Ensuring optimal use. One of these problems is the oscillations of low frequency. Inter-area oscillations are critical and should be detected and damped efficiently in order not to cause a blackout in the power systems. With this respect, it is of great importance to deal with this problem so that power quality of the power systems is continuously supplied by the power system operators. The major objective of this paper is to investigate the oscillations associated with the operation of the system and processed it in inter-area mode. The studied model is a Kundur which is a power system with two area used with implementation of each of selected "Flexible-Alternating- Current-Transmission FACTS devices which were implemented to a specific place in the network to check dynamic performances of Thyristor controlled series compensator (TCSC), Static synchronous compensator STATCOM and Static synchronous series compensator SSSC on inter-area and record the results. The generalized results were conducted to show the operation performance of selected FACTS devices.
