Abstract

With the development of power system towards high efficiency, reliability and intelligence, the application of power electronic technology in power system stability control becomes particularly important. This paper first introduces the research background and significance, emphasizes the key role of power electronic technology in improving the stability of power system, and reviews the research status at home and abroad, and points out the shortcomings of current research. Then, the basic knowledge of power electronics technology is described in detail, including the principle, control strategy and application in power system of various converters. At the same time, the theory of power system stability control is deeply discussed, and the dynamic behavior and stability of power system are analyzed. On this basis, this paper focuses on the mechanism of power electronic technology in power system stability control, including how to improve the stability of the system by adjusting reactive power, improving voltage quality, suppressing harmonics and so on. In addition, this paper also looks forward to the integration trend of power electronics technology and power system stability control, such as the development of smart grid technology will make the combination of the two more closely. In the application analysis part, this paper introduces the application cases of static reactive power compensation technology (SVC and STATCOM), flexible AC transmission system (FACTS), high voltage direct current transmission technology (HVDC) and energy storage technology in stability control in detail, and shows how these technologies can effectively solve practical problems. However, this paper also points out some problems faced by power electronic technology in power system stability control, including the limitations of technology application, economic and cost considerations, reliability and security issues, standardization and interoperability issues. To solve these problems, this paper puts forward corresponding countermeasures, such as strengthening technological innovation and optimization, carrying out comprehensive economic evaluation research, improving equipment reliability and safety, and promoting standardization and interoperability construction. Finally, this paper summarizes the research results and looks forward to the future research direction.
