Abstract
In recent years, energy, environment, deregulation of power utilities have delayed the construction of both generation facilities and new transmission lines. These problems have necessitated a change in traditional concepts and practices of power systems. There are emerging technologies available, which can help electric companies to deal with above problems. One of such technologies is Flexible AC Transmission Systems (FACTS). Among the converter based FACTS devices Static Synchronous Compensator (STATCOM) and Unified Power Flow Controller (UPFC) are the popular FACTS devices. Considering the practical application of the STATCOM and UPFC in power systems, it is of importance and interest to investigate the benefits as well as model these devices for power system steady state operation. We have performed the power flow study of a five bus study system without any FACTS devices and further analyzed it with the converter based FACTS controllers. Programming of the power flow studies stated above is implemented with MATLAB.
1 Introduction
The electricity supply industry is undergoing a profound transformation worldwide. Market forces, scarcer natural resources, and an ever-increasing demand for electricity are some of the drivers responsible for such an unprecedented change. Against this background of rapid evolution, the expansion programmes of many utilities are being thwarted by a variety of well-founded, environmental, land use, and regulatory pressures that prevent the licensing and building of new transmission lines and electricity generating units. An in-
