Control of Doubly Fed Induction Generator for Power Quality Improvement: An Overview

Abstract

Wind energy outweighs other kinds of renewable energy for endless harvestable potential. The integration of wind power into electric grids poses unique challenges because of its stochastic nature, causing a highly erratic generation of power. It affects the power quality and planning of power systems. This article outlines technical issues of wind power integration in the electric grid, providing the power quality interaction of the Doubly fed induction generator (DFIG) in the electric grid perspective. The prevalence of the DFIG in such large numbers necessitates this. An overview of different control strategies for power quality improvement of DFIG, application of energy storage schemes (ESS) and Wind power forecasting techniques, their requirements and advantages for facilitating increased penetration of DFIG in the electric grid is given. Robust integration and deeper penetration of wind power into the future electric grid necessitate balancing power quality improvement, energy storage technology, and wind power forecasting technique of the wind energy system.
