Power Flow Study Including FACTS Devices

A.K. Sahoo, S.S. Dash and T. Thyagarajan

The electric power industry is undergoing the most profound technical, economic and organizational changes since, its inception some one hundred years ago. This paradigm is the result of the liberalization process, stipulated by politics and followed up by industry. In countries like India with fast growing demand of electric power it is difficult to extend the transmission system in time by either building new lines or by introduction of a new voltage level. Power is therefore transmitted through weak system leading to unsatisfactory quality and reliability of power supply. So, the need for new power flow controllers capable of increasing transmission capacity and controlling power flows through predefined transmission corridors will certainly increase. For this reason, as well known in recent years a new class of controllers, Flexible AC Transmission System (FACTS) controllers have rapidly met with favor. Considering the practical application of the FACTS controller, it is of importance to investigate the benefits as well as model these devices for power system steady state operation. We have performed the comprehensive modeling of most popular FACTS devices for power flow study. The effectiveness of modeling and convergence is tested with a five bus study system without any FACTS devices and further analyzed it with different FACTS controllers. The de facto standard Newton-Raphson method is used to solve the nonlinear power flow equation. Also, the study is extended for IEEE 30 bus and IEEE 118 bus system. Programming of the power flow studies stated above is implemented with MATLAB.
