Abstract
As the scale and complexity of power systems continue to expand, traditional AC transmission technologies face numerous challenges such as limited transmission capacity and inadequate stability. To address these issues, Flexible AC Transmission Systems (FACTS) technology has emerged. By installing power electronic devices with rapid regulation capabilities on transmission lines, FACTS can significantly improve the operational performance of power systems. This paper aims to explore the application of FACTS technology in power systems, with the ob jective of enhancing system stability and economic efficiency. Based on an in-depth analysis of relevant studies both domestically and internationally, and considering the actual conditions of China's power system, this research combines theoretical studies with simulation analysis, focusing on the working principles and impacts of typical FACTS devices such as STATCOM and TCSC. The results indicate that STATCOM can substantially enhance voltage stability, while TCSC effectively increases the transmission capacity of lines and suppresses low-frequency oscillations. Furthermore, a FACTS device configuration scheme based on multi-ob jective optimization algorithms is proposed, achieving cost reduction while ensuring safe and stable system operation. This innovative configuration method not only improves the application effectiveness of FACTS technology but also provides new insights for power system planning and operation, which is significant for promoting the widespread application of FACTS technology in China's power systems.
