DFIG Based WT for Frequency Control along with AGC in Multi-Area Systems

Abstract

This paper focuses on Automatic Governor Control (AGC) operational and design perspectives for frequency control in multi-area systems. The transfer function model of the two-area scheme using a minute-perturbation transfer function model is discussed in this paper. The wind turbine (WT) containing a doubly fed induction generator (DFIG) is considered in this study of frequency control. The optimal tuning of DFIG controllers is also focused on in this paper. The optimal tuning process is very complicated due to the involvement of additional tuning parameters. The complete simulation analysis of optimal tuning of DFIG controllers and frequency control of the two-area system using AGC has been demonstrated. Furthermore, the analyses have been demonstrated to evaluate the system impingement of 20% and 50% penetration for wind generation. © 2021. All Rights Reserved.
