摘要

Abstract

With the integration of large-scale wind turbines (WTs) into grids via electronic interfaces

power systems are suffering from increasingly serious frequency stability risks. Due to the large number of WTs and their complex dynamic characteristics

operators encounter challenges in coordinating single WTs to provide frequency support directly

and it is necessary to assess the primacy frequency regulation (PFR) capability of wind farms. To cope with the problems of solving complexity and incomplete parameters

a data-driven state space mappingbased linear model for wind farms is developed in this paper to assess the maximum PFR capability. With Koopman operator theory (KOT)

the proposed method transforms wind farm PFR nonlinear dynamics into a linear lift-dimension algebraic model

which can assess the maximum PFR capability of wind farms based on historical data in real-time. The simulation results demonstrate that the proposed method has the advantages of fast solving

independence on model parameters

and lower training data requirements.
