Abstract
The wind power generation is a rapidly growing grid integrated renewable energy (RE) technology with an installed capacity of 539.291 GW. The capability of the wind energy conversion system (WECS) to remain integrated into the utility network in the case of low voltage events is called low-voltage ride-through (LVRT) capability. This paper offers a comprehensive overview of improvement techniques of the LVRT capability in WECS to increase the wind energy penetration level in the utility grid. Exhibited portrait manifests a broad spectrum of 1) wind turbines, 2) electrical generators used for wind power applications, 3) international grid codes applicable for grid integration of WECS, 4) LVRT fundamentals in WECS, 5) wind turbines LVRT methods by doubly fed induction generator (DFIG), 6) wind turbines LVRT methods by permanent magnet synchronous generators (PMSG), and 7) LVRT methods of wind turbines using squirrel cage induction generator (SCIG). This ready-reckoner paper critically reviews and classifies more than 190 research papers on LVRT issues, practices, and available technologies for grid integration in wind energy systems, and it aims to be a quick reference for the researchers, designers, manufacturers, and engineers working in the same field.
Highlights
Penetration of renewable energy (RE) into the utility grid contributes significantly to reduce the greenhouse gases emission [1]
Wind energy power plants based on doubly fed induction generator (DFIG), permanent magnet synchronous generators (PMSG), and squirrel cage induction generator (SCIG) have extensively integrated into the utility grid [3]
Reference [24] presents a detailed study of requirements defined by grid codes, which help the wind turbines to participate in frequency control and synthetic inertia
Summary
Penetration of renewable energy (RE) into the utility grid contributes significantly to reduce the greenhouse gases emission [1]. The multifold extensive research work is on the pathway to design the efficient wind energy conversion systems (WECSs), international grid codes and associated implementation of LVRT methods for wind turbines with WECSs, DFIG, PMSG, and SCIG based technologies. A comprehensive review and classification of existing methods in this regard are essential to accelerate the pace of associated research This bibliographic guide book can help the researchers, designers, manufacturers, and engineers to increase the penetration level of wind energy in the utility grid network. This manuscript aims to present a comprehensive overview of LVRT capability improvement of wind power plants. It includes wind turbine and wind power plants electrical generators.
