Book Description
In this thesis, a Type III (Doubly Fed Induction Generator) wind generation system is analyzed and modeled. The results of this analysis are used to design and build a testbed for protection design and testing. The specic generator modeled is the four-pole, 10HP DFIG driven by a four-pole, 10HP induction machine powered by an adjustable speed drive. The testbed is made for research and development to analyze the DFIG during fault conditions. A future goal for the overall project is to design protection equipment for wind farms. The thesis presents the steady-state modelling and dynamic modelling of the DFIG, followed by a detailed switching model of the two-level voltage source converter (VSC). Two VSCs form a back-to-back converter which connects between the rotor windings and the power system. The grid side converter (GSC) interacts with the power system and the DC bus and is designed to maintain a constant DC bus voltage. The GSC is controlled to exchange power between the DC bus and the power system while tracking the system frequency. The power circuit, sensor circuit and control circuit for GSC are first designed and validated in simulation, then implemented in hardware. The protection logic is designed to protect the power electronics from overcurrent and overvoltage. The power control of the DFIG is achieved by rotor side converter (RSC) control strategies. The functionality of the RSC control is validated with simulation and could be implemented in hardware with similar hardware setups as the GSC.

Book Description
This book deals with quantifying and analyzing the risks associated with sustainable energy technology growth in electric power systems, and developing appropriate models and methodologies to mitigate the risks and improve the overall system performance. The rapid increase in the installation of renewable energy sources in electric power systems has given rise to a wide range of problems related to planning and operation of power systems to maintain quality, stability, reliability and efficiency. Additionally, there is a growing global environmental concern regarding increasing emissions from the electric power generation required to meet rising energy needs and support sustainable and inclusive development. The phenomenon of low voltage ride through (LVRT), common to wind energy systems, is discussed, and ways to tackle the same are proposed in the first chapter. Subsequent chapters propose methods of optimizing a sustainable and smart microgrid, and supplying electricity to remote areas of a developing country with no immediate possibility of national grid extension. The economic benefit and technical challenges of forming localized minigrid are also discussed. The book proposes a method for reliability assessment of a power grid with sustainable power transportation system. The issue of weak link in power system is very important as it will provide the system operators and planners to take necessary measures to strengthen the system. An approach to determine the weak parts of the system and its unreliability is proposed. With increasing installation of HVDC power transmission and development of efficient and low cost power electronic devices, the DC microgrids are becoming a common phenomenon. Their existence together with AC Grids result in Hybrid AC/DC Microgrids, which are discussed in this book. It further presents a method for reliability evaluation of a distribution system with network reconfiguration in the presence of distributed generation. The important problems in sustainable energy growth, and their potential solutions discussed and presented in the book should be of great interest to engineers, policy makers, researchers and academics in the area of electric power engineering.
