Analytical Calculation of Wind Power Hosting Capacity Considering Dynamic Frequency Stability and Energy Storage-based Fast Frequency Support
With the continuous increase in wind power penetration,the integration of high-penetration wind power poses severe challenges to the frequency security and stability of power systems. To address this issue,this paper proposes an analytical calculation method for wind power hosting capacity that considers dynamic frequency stability and energy storage-based fast frequency support. Based on the fast frequency response characteristics of energy storage systems,a system frequency response (SFR) model incorporating energy storage is established,and analytical expressions for the maximum rate of change of frequency,maximum frequency deviation,and quasi-steady-state frequency deviation are derived. Furthermore,with frequency security as the constraint,the wind power hosting region is accurately characterized for two scenarios: with and without fast frequency support from energy storage. Simulation results demonstrate that the proposed method can accurately and reliably calculate the wind power hosting stability region and penetration limit under different power disturbances,verifying the effectiveness and accuracy of the model.
