This book was released on 2012-07-03 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: EVALUATION OF OCEAN-ENERGY CONVERSION BASED ON LINEAR GENERATOR CONCEPTS As the world continues to demand greater productivity and lifestyle enrichment through technological advancements, the demand for electrical power is predicted to escalate dramatically. Thus far, this increased demand has been primarily supplied from fossil fueled plants. Unfortunately, the burning of fossil fuels produce harmful carbon dioxide pollution as a by-product. It has been hypothesized that unless a clean, renewable, and efficient alternate source of energy is found soon, the world may either exhaust its supplies of energy-producing materials or drastically degrade its environment. However, motions that occur naturally, such as ocean waves, can play a significant role in generating environmentally safe and economically viable energy for human utilization. The focus of this work predicts the electrical power generation capabilities from a seabed mounted linear generator tethered to a floating buoy heaving under the influence of passing ocean surface waves. Mathematical models are introduced which simulate the oceans' surface conditions under both the regular (basic) and irregular (natural) wave regimes, the heave (vertical displacement) response for a floating buoy, and the resulting electrical output parameters of the linear generator. Within these models, various physical and electrical parameters are altered in an attempt to generate a greater output power for a given sea state condition, making the Wave Energy Converter (WEC) more efficient. It is shown theoretically that the buoy can be designed to have a greater heave response than that of the height of a passing wave resulting in an increase in generated power from the linear generator. Author Information: Dr. Michael A. Stelzer is a Certified Project Manager and Senior Electronic Technician with a Ph.D. in Electrical and Computer Engineering. During his career to date, Mr. Stelzer has published four additional educational titles and has been admitted into Cambridge Who's Who top 101 industry experts.

Download or read book Energy Harvesting written by Alireza Khaligh and published by CRC Press. This book was released on 2017-12-19 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Also called energy scavenging, energy harvesting captures, stores, and uses "clean" energy sources by employing interfaces, storage devices, and other units. Unlike conventional electric power generation systems, renewable energy harvesting does not use fossil fuels and the generation units can be decentralized, thereby significantly reducing transmission and distribution losses. But advanced technical methods must be developed to increase the efficiency of devices in harvesting energy from environmentally friendly, "green" resources and converting them into electrical energy. Recognizing this need, Energy Harvesting: Solar, Wind, and Ocean Energy Conversion Systems describes various energy harvesting technologies, different topologies, and many types of power electronic interfaces for stand-alone utilization or grid connection of energy harvesting applications. Along with providing all the necessary concepts and theoretical background, the authors develop simulation models throughout the text to build a practical understanding of system analysis and modeling. With a focus on solar energy, the first chapter discusses the I−V characteristics of photovoltaic (PV) systems, PV models and equivalent circuits, sun tracking systems, maximum power point tracking systems, shading effects, and power electronic interfaces for grid-connected and stand-alone PV systems. It also presents sizing criteria for applications and modern solar energy applications, including residential, vehicular, naval, and space applications. The next chapter reviews different types of wind turbines and electrical machines as well as various power electronic interfaces. After explaining the energy generation technologies, optimal operation principles, and possible utilization techniques of ocean tidal energy harvesting, the book explores near- and offshore approaches for harvesting the kinetic and potential energy of ocean waves. It also describes the required absorber, turbine, and generator types, along with the power electronic interfaces for grid connection and commercialized ocean wave energy conversion applications. The final chapter deals with closed, open, and hybrid-cycle ocean thermal energy conversion systems.

Available in PDF, EPUB and Kindle. Book excerpt: Marine Sources of Energy focuses on international research and development activities in the field of marine sources of energy such as waves, tides, currents, winds, and salinity gradients. General and specific recommendations for future research and development programs are presented, along with plans for action to demonstrate and amplify the potential of a number of marine energy sources both in Europe and in developing countries. This book consists of seven chapters and begins with a discussion on offshore coastal wind energy conversion, along with the advantages and limitations of wind energy and its economic aspects. The reader is then introduced to ocean thermal energy conversion (OTEC), with particular reference to the factors that must be taken into account when selecting sites for an OTEC plant. The following chapters consider the solar pond concept and its possible application to heat production and energy production; and the economic aspects of wave and tidal energy conversion. Other possibilities of marine energy conversion, including marine currents and biomass energy conversion, are evaluated. This monograph will be of interest to government officials and policymakers concerned with marine and other alternative sources of energy.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Seaformatics project is a five year AIF project that intends to develop wireless marine sensors for use in monitoring seabed processes. The sensor pods will be selfpowered through ocean bottom currents and will be able to communicate with each other This research is focused on development of a device to harvest energy from water currents near the ocean floor to power such seabed marine technologies. The research is very interdisciplinary in nature and involves design, structures, fluid dynamics, nonlinear control and power electronics, which makes it very challenging. A major outcome of the research is a robust small marine current energy conversion system that can extract power from the low marine current. A prototype was designed and constructed. It was tested in the towing tank in the Faculty of Engineering at Memorial University of Newfoundland. Power output was controlled using a DSP PI controller. The device consisted of a watertight hull. An electric generator was installed inside the hull and the turbine rotor was installed outside. The rotor of the device has blades like conventional wind turbines but the blades face forward into the flow and not perpendicular to it. This unique arrangement of the blades ensures high starting torque even in low currents. It used simple flat plate blades. A unique magnetic torque coupler was used to connect the generator to the turbine. This used sets of magnets inside and outside that repelled each other. Besides acting as a coupler, this arrangement of magnets also acted as a bearing. Ideally, it would have been good to use a generator designed specifically for the device but that would have been expensive and beyond the project budget so we used a commercial generator. To increase the rotational speed of this generator, a set of gears was inserted between the turbine and generator shafts. Computational Fluid Dynamics analysis and Potential Flow Hydrodynamics Theory were used to study the hydrodynamics of the rotor. This allowed us to explore geometry variations too expensive to study experimentally. For example, it showed that curved blades would give significantly more power than flat blades. This dissertation also presents an adaptive back stepping nonlinear maximum power point tracking (MPPT) control strategy for the system. Because of tow tank scheduling constraints, this was tested in simulation only. The proposed control strategy does not require any flow sensors and also does not need the parameters of a PMSG. A Lyapunov based online estimation approach is used to continually estimate the input voltage and the output load resistance of the converter. Detailed simulation results of the proposed adaptive back stepping control are presented and fully analyzed. Simulation results demonstrate that the proposed nonlinear controller can incessantly extract maximum power from the ocean current at various flow speeds.

Available in PDF, EPUB and Kindle. Book excerpt: The waves that animate the surface of the oceans represent a deposit of renewable energy that for the most part is still unexploited today. This is not for lack of effort, as for more than two hundred years inventors, researchers and engineers have struggled to develop processes and systems to recover the energy of the waves. While all of these efforts have failed to converge towards a satisfactory technological solution, the result is a rich scientific and technical literature as well as extensive and varied feedback from experience. For the uninitiated, this abundance is an obstacle. In order to facilitate familiarization with the subject, we propose in this work a summary of the state of knowledge on the potential of wave energy as well as on the processes and technologies of its recovery (wave energy converters). In particular, we focus on the problem of positioning wave energy in the electricity market, the development of wave energy conversion technologies from a historical perspective, and finally the energy performance of the devices. This work is aimed at students, researchers, developers, industry professionals and decision makers who wish to acquire a global perspective and the necessary tools to understand the field. Reviews the state of knowledge and developments on wave energy recovery Presents the history of wave energy recovery Classifies the various systems for recovering this type of energy

Available in PDF, EPUB and Kindle. Book excerpt: The effects of human-caused global warming are obvious, requiring new strategies and approaches. The concept of business-as-usual is now no longer beneficial. Extraction of renewable energy in marine environments represents a viable solution and an important path for the future. These huge renewable energy resources in seas and oceans can be harvested, including wind, tide, and waves. Despite the initial difficulties related mostly to the elevated operational risks in the harsh marine environment, newly developed technologies are economically effective or promising. Simultaneously, many challenges remain to be faced. These are the main issues targeted by the present book, which is associated with the Special Issue of Energies Journal entitled “Renewable Energy in Marine Environment”. Papers on innovative technical developments, reviews, case studies, and analytics, as well as assessments, and papers from different disciplines that are relevant to the topic are included. From this perspective, we hope that the results presented are of interest to for scientists and those in related fields such as energy and marine environments, as well as for a wider audience.
