A comparative study of the impact of FACTS devices on the voltage stability in the power systems

Abstract

Over the past few decades, demand for electricity has increased significantly, whereas expansions in power generation and transmission have been severely restricted due to resource constraints and environmental constraints. As a result, most transmission lines were heavily loaded, and efficiency of the power system became a limiting factor for transmitting electrical power. It is considered a major and demanding problem to establish a secure and stable operation of the electricity networks. Because of its significance, the voltage stability of the power systems has received considerable attention from researchers. Therefore, this paper sheds light on a substantial number of the adopted techniques, including STATCOM and SVC devices to achieve this purpose. A case study was deemed to be an IEEE bus-14 device. To simulate this analysis, a MATLAB package has been utilized. The simulation results showed that by using these methods, the voltage stability of the related system is considerably improved.
