A Novel Method for Calculating Steady-State Operating Conditions for DFIG-Based Wind Turbines
(Institute of Electrical and Electronics Engineers Inc., 2024) Lazar, A.; Navaneeth, K.; Kotian, S.M.
This paper utilizes a modified Newton-Raphson (MNR) iterative technique for steady-state initialization of doubly fed induction generator (DFIG)-based wind turbine (WT) connected to the grid. The MNR technique discussed in this paper is based on the Adomian decomposition method. The steady-state values obtained using the MNR method are compared with those obtained using the conventional Newton-Raphson (NR) method to check the accuracy of the MNR method. Further, the number of iterations taken for both methods to converge was compared. From the case studies, it is noted that the MNR method results in steady-state values, which are identical to those obtained using the NR method with lesser number of iterations. The steady-state values calculated using the MNR method are utilized to carry out the eigenvalue analysis and time-domain simulations of a DFIG-based WT power system. Â© 2024 IEEE.
