Multiple Wind Farms Modeling Method for Sub/super-synchronous Oscillation Characteristics Analysis

Le résumé fourni par la source

To address the issue of high model order and low simulation efficiency resulting from large-scale wind power integration during the analysis of sub/super-synchronous characteristics, this article puts forward a multiple wind farms modeling method for sub/super-synchronous characteristics analysis. Firstly, the impedance model of the wind farm is constructed, which is applicable to analyzing the sub/supersynchronous characteristics. Secondly, a multiple wind farms modeling method is proposed. The principal influencing factors in the oscillation analysis are taken as the clustering objects, and the OPTICS clustering algorithm is employed to quickly acquire the wind farm clustering set and clustering center. Finally, by taking an actual power grid as an instance, the efficacy of the proposed approach in the analysis of sub/super-synchronous characteristics is verified.
