Abstract

This paper proposes a noniterative approach to calculate steady-state operating conditions of doubly fed induction generator (DFIG)-based wind turbines. The proposed approach can be applied to calculate steady-state operating conditions for the full-order dynamic model of DFIG-based wind turbines under d-q reference frame. Lossy DFIG back-to-back converters can be well supported, and nonzero reactive power delivery throughDFIG grid-side converters can be handled. This noniterative approach encounters no convergence issues, which guarantees fast computation speed. It provides analytical solutions to the steady-state operating conditions of DFIG-based wind turbines. The proposed method could potentially be applied to obtain steady-state operating conditions before performing eigenvalue analysis and electromagnetic simulations for wind farms. Simulations performed on a single-machine-infinite-bus test system and a multibus test system verify the effectiveness of the proposed method.
