Due to environmental pollution and climate change, the use of renewable energy sources as an alternative means of power generation is on the rise globally. This is because of their clean nature, which makes them ecofriendly with little or no pollution compared to the traditional fossil fuel power-generation power plants.
Among the various renewable energy sources, wind energy is one of the most widely employed, due to its promising technology. Wind turbine technologies could be classified into two groups as follows: Fixed Speed Wind Turbines (FSWTs) and Variable Speed Wind Turbines (VSWTs). There have been tremendous improvements in wind turbine technology over the years, from FSWTs to VSWTs, as a result of fast innovations and advanced developments in power electronics. Thus, the VSWTs have better wind energy capture and conversion efficiencies, less acoustic noise and mechanical stress, and better power quality in power grids without support from external reactive power compensators due to the stochastic nature of wind energy.
The two most widely employed VSWTs in wind farm development are the Doubly Fed Induction Generator (DFIG) and the Permanent Magnet Synchronous Generator (PMSG) wind turbines. In order to solve transient stability intricacies during power grid faults, this book proposes different control strategies for the DFIG and PMSG wind turbines.
Kenneth Eloghene Okedu was a research fellow in the Department of Electrical and Computer Engineering, Massachusetts Institute of Technology (MIT), Boston, USA, in 2013. He obtained his PhD from the Department of Electrical and Electronic Engineering, Kitami Institute of Technology, Japan, in 2012. He received his BSc and MEng in Electrical and Electronic Engineering from the University of Port Harcourt, Nigeria, in 2003 and 2007, respectively, where he was retained as a faulty member from 2005 until the present day. He has also been a visiting faculty member at the Abu Dhabi National Oil Company (ADNOC) Petroleum Institute. He was also a visiting faculty member at the Caledonian College of Engineering, Oman (Glasgow Caledonian University, UK). He is presently a visiting professor in the Department of Electrical and Computer Engineering, National University of Science and Technology (NUST), Oman, and an adjunct professor in the Department of Electrical and Electronic Engineering, Nisantasi University, Turkey. He was recognized as a top 1% peer reviewer in Engineering by Publons in 2018 and 2019 and was the editor's pick in the Journal of Renewable and Sustainable Energy in 2018. Dr. Okedu has published several books and journals/transactions in the field of renewable energy. He is an editor for including Frontiers in Renewable Energy Research (Smart Grids), Energies (MDPI), International Journal of smart Grids, International Journal of Electrical Engineering, Mathematical Problems in Engineering, and Trends in Renewable Energy. His research interests include power system stability, renewable energy systems, stabilization of wind farms, stability analysis of Doubly-Fed Induction Generators (DFIGs) and Permanent Magnet Synchronous Generators (PMSG) variable speed wind turbines, augmentation and integration of renewable energy into power systems, grid frequency dynamics, wind energy penetration, FACTS devices and power electronics, renewable energy storage systems, and hydrogen and fuel cells.
