This study targets the key issues of multi-time-and-space-scale frequency coordinated control in high-proportion new energy power systems, and constructs a comprehensive dataset covering frequency dynamic characteristics, parameter influence mechanisms and coordinated control strategies via multi-scenario simulation and numerical analysis methods. Firstly, based on the improved IEEE 4-machine 2-area system model, this study quantitatively analyzes the dynamic interaction characteristics of coordinated frequency regulation between new energy units and conventional thermal units, acquires frequency response curves, model error analysis matrices and new energy grid connection impact evaluation indicator data, and reveals the influence law of multi-machine coupling on the temporal and spatial distribution characteristics of system frequency. Secondly, by building a 3-area time-domain simulation scenario, this study systematically investigates the differentiated action mechanisms of core parameters such as inertia constant and droop coefficient on key indicators including frequency nadir and rate of change of frequency (RoCoF), and clarifies the nonlinear mapping relationship of coordinated optimization of frequency regulation resources. Furthermore, in the IEEE 10-machine 39-bus system, this study innovatively proposes a distributed coordinated control strategy for multiple wind farms, verifies the adaptability of the control strategy under different disturbance scenarios through optimal power reference curve fitting and communication load compression technology, and forms a complete data chain including dynamic response curves, power tracking characteristics and rotor kinetic energy release processes. This dataset realizes data connectivity from single-area dynamic responses to coordinated frequency regulation in complex power grids, and provides systematic data support for improving the frequency regulation capability and safe and stable operation of new-type power systems by revealing the deep mechanisms of multi-time-and-space-scale frequency control.
