摘要：
Estimating the inertia demand of the system through the frequency security early warning and completing the rapid response of the frequency through the virtual inertia control by the wind turbine and energy storage are critical to ensure the stable operation of the novel power system.In this paper, the inertia requirements of the system under the frequency security constraints are analyzed.Following that, the virtual inertia response characteristics of wind turbines and energy storage devices are analyzed.By establishing the frequency response model of the wind-storage system with virtual inertia, the frequency change characteristics and inertia response time of the system are then calculated.On this basis, in order to complete the frequency early warning, the reserve capacity of the virtual inertia of the wind turbine and the energy storage is evaluated offline through the wind storage operation constraints.According to the system inertia demand, the reference disturbance power is estimated, and the wind-storage cooperative fast frequency response technology is proposed to allocate the virtual inertias between wind turbines and energy storage devices.Finally, a typical regional simulation network with high penetration of wind power generation is carried out to verify the proposed control strategy.The results demonstrate that the multi-source frequency fast response can be achieved by the cooperation of conventional generators, wind turbines and energy storage devices, thus meeting the security requirements of system frequency. ©2023 Chin.Soc.for Elec.Eng.
