Key technologies for frequency security and stability in new power systems 新型电力系统频率安全稳定关键技术
With the continuous increase of the proportion of new energy connected to the grid, the frequency response ability of power systems is seriously lacking, and the spatial and temporal distribution characteristics are significant, which make the frequency security situation increasingly severe. The traditional single-unit power system frequency response analysis model is no longer able to satisfy the frequency analysis requirements of new power system development trend due to numerous limiting factors. Therefore, it is necessary to explore more accurate and efficient frequency response analysis models in frequency response analysis methods, as well as to explore resources that can improve the frequency response ability of power systems in regulation methods. 随着新能源并网比例的不断增加，电力系统频率响应调节能力愈发不足，时空分布特征愈发显著，频率安全形势日益严峻。由于诸多限制因素，传统的分析方法已无法满足新电力系统发展趋势的频率要求。因此，有必要探索更准确、更高效的分析模型，探索可以提高电力系统频率响应能力的资源。
This Special Session is based on this to conduct extensive studies, aiming to gather experts and scholars in related fields to exchange ideas and jointly improve the frequency security and stability levels of new power systems.本次专题会议正是在此基础上进行广泛研究，旨在聚集相关领域的专家学者交流意见，共同提高新型电力系统的频率安全稳定水平。
