Abstract
The development of new power systems has put forward higher requirements for DC circuit breakers. Flexible DC circuit breakers have attracted attention due to their ability to quickly cut off fault currents and their flexibility. This paper aims to explore the key technologies of flexible DC circuit breakers for new power systems and their economic optimization methods. By analyzing the deficiencies of existing technologies, an improved design scheme is proposed to enhance their performance and reduce costs. Firstly, the working principle of flexible DC circuit breakers and their importance in new power systems are outlined. Then, the key technical challenges and solutions are discussed in depth, and a detailed economic analysis is carried out. The proposed optimization strategy can not only significantly improve the performance of flexible DC circuit breakers but also effectively reduce the overall cost, providing a strong guarantee for the stable operation of new power systems.
Key words： Flexible DC circuit breaker; Key technologies; Economic optimization; New power system
