摘要：

With wind power penetration increasing, it is crucial to accurately estimate the impact of wind power generation on grid inertia levels. This article proposes a microgrid inertia estimation model with distributed wind power generation, considering the impact of wind conditions on doubly-fed induction generators (DFIG). The frequency response mechanisms of a DFIG-based wind turbine (WT) are investigated across different wind speed zones. A non-synchronous inertia matrix is formulated, accounting for the impact of varying wind speeds. A Multiple-Input Single-Output (MISO)-based identification method is proposed for identifying the elements of the inertia matrix. The simulation reveals that the wind speed affects the microgrid inertia response through the turbine speed control. The method can assess the risk of frequency issues and assist in the safe and stable operation of microgrids.
