Wind Energy Systems Solutions for Power Quality and Stabilization

Wind Energy Systems Solutions for Power Quality and Stabilization

Unlike conventional power plants wind plants emit no air pollutants or greenhouse gases—and wind energy is a free renewable resource. However the induction machines commonly used as wind generators have stability problems similar to the transient stability of synchronous machines. To minimize power frequency and voltage fluctuations caused by network faults or random wind speed variations control mechanisms are necessary. Wind Energy Systems: Solutions for Power Quality and Stabilization clearly explains how to solve stability and power quality issues of wind generator systems. Covering fundamental concepts of wind energy conversion systems the book discusses several means to enhance the transient stability of wind generator systems. It also explains the methodologies for minimizing fluctuations of power frequency and voltage. Topics covered include: An overview of wind energy and wind energy conversion systems Fundamentals of electric machines and power electronics Types of wind generator systems Challenges in integrating wind power into electricity grids Solutions for power quality problems Methods for improving transient stability during network faults Methods for minimizing power fluctuations of variable-speed wind generator systems This accessible book helps researchers and engineers understand the relative effectiveness of each method and select a suitable tool for wind generator stabilization. It also offers students an introduction to wind energy conversion systems providing insights into important grid integration and stability issues. | Wind Energy Systems Solutions for Power Quality and Stabilization

Performance of DFIG and PMSG Wind Turbines

Performance of DFIG and PMSG Wind Turbines

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. | Performance of DFIG and PMSG Wind Turbines

The New Tenement Residences in the Inner City Since 1970

The New Tenement Residences in the Inner City Since 1970

This book examines new tenements—dense medium-rise multi-storey residences that have been the backbone of European inner-city regeneration since the 1970s and came with a new positive view on urban living. Focusing principally on Berlin Copenhagen Glasgow Rotterdam and Vienna it relates architectural design to an evolving intellectual framework that mixed anti-modernist criticism with nostalgic images and strategic goals and absorbed ideas about the city as a generator of creativity locale of democratic debate and object of personal identification. This book analyses new tenements in the context of the post-functionalist city and its mixed-use neighbourhoods redeveloped industrial sites and regenerated waterfronts. It demonstrates that these buildings are both generators and outcome of an urban environment characterised by information exchange rather than industrial production individual expression rather than mass culture visible history rather than comprehensive renewal and conspicuous difference rather than egalitarianism. It also shows that new tenements evolved under a welfare state that all over Europe has come under pressure but still to a certain degree balances and controls heterogeneity and economic disparities. | The New Tenement Residences in the Inner City Since 1970

Advanced Electric Drive Vehicles

Advanced Electric Drive Vehicles

Electrification is an evolving paradigm shift in the transportation industry toward more efficient higher performance safer smarter and more reliable vehicles. There is in fact a clear trend to move from internal combustion engines (ICEs) to more integrated electrified powertrains. Providing a detailed overview of this growing area Advanced Electric Drive Vehicles begins with an introduction to the automotive industry an explanation of the need for electrification and a presentation of the fundamentals of conventional vehicles and ICEs. It then proceeds to address the major components of electrified vehicles—i. e. power electronic converters electric machines electric motor controllers and energy storage systems. This comprehensive work: Covers more electric vehicles (MEVs) hybrid electric vehicles (HEVs) plug-in hybrid electric vehicles (PHEVs) range-extended electric vehicles (REEVs) and all-electric vehicles (EVs) including battery electric vehicles (BEVs) and fuel cell vehicles (FCVs) Describes the electrification technologies applied to nonpropulsion loads such as power steering and air-conditioning systems Discusses hybrid battery/ultra-capacitor energy storage systems as well as 48-V electrification and belt-driven starter generator systems Considers vehicle-to-grid (V2G) interface and electrical infrastructure issues energy management and optimization in advanced electric drive vehicles Contains numerous illustrations practical examples case studies and challenging questions and problems throughout to ensure a solid understanding of key concepts and applications Advanced Electric Drive Vehicles makes an ideal textbook for senior-level undergraduate or graduate engineering courses and a user-friendly reference for researchers engineers managers and other professionals interested in transportation electrification.

Island Power Systems

Island Power Systems

A major concern of island power systems is frequency stability. A power system is said to be frequency stable if its generators are able to supply their loads at a frequency within acceptable limits after a disturbance. Frequency instability occurs if load-generation imbalances are not corrected in appropriate manner and time. Since island power systems are more sensitive to frequency instability than large ones due to the smaller number of generators online and the lower inertia they require a larger amount of primary reserve per generator. This book provides a worldwide overview of island power systems describing their main features and issues. Split into two parts the first part examines the technical operation and in particular frequency stability of island power systems and its technical solutions including more efficient underfrequency load-shedding schemes. The chapters explore both conventional and advanced load-shedding schemes and consider the improvement of these schemes by making them more robust and efficient. Advanced devices are modelled and analyzed to enhance frequency stability and reduce the need for load shedding. In the second part the economic operation of island power systems is explored in detail. For that purpose regulations and economic operations (centralized vs. market scheme) are reviewed by the authors. The authors discuss models for renewable energy sources and for advanced devices and systems such as demand-side management energy storage systems and electric vehicles. This book will be critical reading to all researchers and professionals in power system planning and engineering electrical/power delivery RES and control engineering. It will also be of interest to researchers in signal processing and telecommunications and renewable energy as well as power system utility providers.
