Numerical simulation study reveals impacts of active power boost magnitude and duration from deloaded wind turbines on grid frequency, suggesting optimal tuning for post-contingency stability.
The growing deployment of Type‐4 wind turbine generators (WTs), driven by carbon neutrality and net‐zero policies, may challenge frequency stability in power systems. Unlike synchronous generators, WTs connected to the power system via converters do not provide inertia. Nevertheless, by leveraging the fast response characteristics of converters, WTs can rapidly increase their active power and effectively serve as fast frequency response resources that cannot be obtained from synchronous generators. Motivated by these characteristics, we previously proposed active power control strategies for WTs to enhance frequency stability. However, the performance of the proposed method may vary depending on the magnitude and duration of the post‐contingency active power support provided by WTs. Therefore, numerical simulations were conducted to investigate the impact of varying the active power increase provided by WTs following a generation loss contingency on both frequency stability and WT operation.
