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. 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.

The topics are, but not limited to the followings:

（1）Modeling, evaluation, mechanism analysis, and optimization control of frequency security in new power systems

（2）Optimization control and configuration strategies of new power systems considering frequency dynamic characteristics

（3）Optimization configuration, dispatch, and control strategies for flexible resources such as energy storage and virtual power plants to participate in frequency response

（4）Coordination control of multi-type resources for providing frequency regulation in new power systems

（5）Multi-temporal and -spatial couplings and wide-area control technology for inertia-power-frequency in new power systems

（6）Power-electricity balancing and inter provincial mutual aid coordination dispatch for multi-level power grids

（7）Market mechanism for frequency security in new power systems
