Direct-driven permanent magnet wind turbines show no inertia response to the system through the grid connection of full-power converters, resulting in increased frequency fluctuation, poor response effect and reduced stability time of the system under sudden load and sudden wind speed conditions. Based on this, an inertia control method of direct-drive permanent magnet wind turbine under high wind power penetration is proposed, and the model of direct-drive permanent magnet wind turbine is built by designing functional modules to improve the synchronous control effect under high wind power penetration. The vector control calculation method is used to design the virtual inertia control parameters, and the decoupling quantity is introduced to decouple the parameters with filter inductance, so as to improve the supporting capacity of power grid frequency fluctuation. The simulation results show that the proposed method has a fast frequency response under sudden load change, and it drops to the lowest value of 49.16 Hz at 12.14 s. Under the condition of sudden change of wind speed, the system frequency rises to the highest value of 50.38 Hz at 12.94 s. It is proved that the proposed method has a certain suppression effect on the amplitude of frequency change, effectively shortens the time for the system frequency to return to steady state, and thus has more advantages.<\/jats:p>","DOI":"10.3233\/jcm-226726","type":"journal-article","created":{"date-parts":[[2023,2,14]],"date-time":"2023-02-14T10:50:42Z","timestamp":1676371842000},"page":"2225-2235","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Inertia control method of direct drive permanent magnet wind turbine under high wind power permeability"],"prefix":"10.66113","volume":"23","author":[{"given":"Fang","family":"Wang","sequence":"first","affiliation":[{"name":"College of Energy and Machinery, Dezhou University, Dezhou, Shandong 253000, China"},{"name":"E-mail:"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"55691","published-online":{"date-parts":[[2023,7]]},"reference":[{"issue":"2","key":"e_1_3_1_2_2","first-page":"62","article-title":"Comparative study of wind turbine power curve modeling method","volume":"38","author":"Liang T","year":"2021","unstructured":"LiangT CuiJ ShiH LiZQ.
