  • Application of Risk Evaluation to Renewable Energy Systems

    While wind and solar energies provide new generation sources, additional operational risks have been also brought to power systems. This chapter discusses, in two separate sections, the risk evaluation methods for two special elements¿¿-¿¿wind turbine power converter system (WTPCS) and photovoltaic (PV) power system. In each section, establishing the relationship between the failure rates of electronic components and wind speed or insolation is a main thread. In the first section, a typical four-quadrant WTPCS with a permanent-magnet synchronous generator is used as an example to investigate the effects of wind speed and wind generator parameters on WTPCS risk. In the second section, a real life central-inverter PV system and an alternative design option with string inverter topologies are utilized to investigate the effects of various factors on the PV power system risk.

    The development and deployment of cleaner energy technologies have become globalized phenomena. Yet despite the fact that energy-related goods account for more than ten percent of international trade, policy makers, academics, and the business community perceive barriers to the global diffusion of these emerging technologies. Experts point to problems including intellectual property concerns, trade barriers, and developing countries' limited access to technology and funding. In this book, Kelly Gallagher uses analysis and case studies from China's solar photovoltaic, gas turbine, advanced battery, and coal gasification industries to examine both barriers and incentives in clean energy technology transfer. Gallagher finds that the barriers are not as daunting as many assume; these technologies already cross borders through foreign direct investment, licensing, joint R&D;, and other channels. She shows that intellectual property infringement is not as widespread as business leaders fear and can be managed, and that firms in developing countries show considerable resourcefulness in acquiring technology legally. She finds that financing does present an obstacle, especially when new cleaner technologies compete with entrenched, polluting, and often government-subsidized traditional technologies. But the biggest single barrier, she finds, is the failure of government to provide sensible policy incentives. The case studies show how government, through market-formation policy, can unleash global market forces. Gallagher's findings have theoretical significance as well; she proposes a new model of global technology diffusion that casts doubt on aspects of technology transfer theory.

  • Universal Operation of Small/Medium???Sized Renewable Energy Systems

    In the scenario of the grid???interactive distributed power generation systems the role of the power converters control is fundamental involving different issues: power flow control, synchronization with the main grid, reactive power capability, voltage regulation at the point of common coupling and power quality constraints. These matters are tackled in the chapter focusing on photovoltaic and small wind turbine systems. Starting from the basic main features of a renewable energy system, such as the current and voltage control of the power converter, the focus of the analysis is moved to the management of the transition among the different operation modes: grid???connection, stand???alone operation and synchronization. Suggestions about the control design and the parameters tuning procedure are provided. The possibility to improve the power converter of the renewable energy system with ancillary features is also investigated.

    Nonimaging optics is a subdiscipline of optics whose development over the last 35-40 years was led by scientists from the University of Chicago and other cooperating individuals and institutions. The approach provides a formalism that allows the design of optical devices that approach the maximum physically attainable geometric concentration for a given set of optical tolerances. This means that it has the potential to revolutionize the design of solar concentrators. In this monograph, the basic practical applications of the techniques of nonimaging optics to solar energy collection and concentration are developed and explained. The formalism for designing a wide variety of concentrator types, such as the compound parabolic concentrator and its many embodiments and variations, is presented. Both advantages and limitations of the approach are reviewed. Practical and economic aspects of concentrator design for both thermal and photovoltaic applications are discussed as well. The hole range of concentrator applications from simple low-concentration nontracking designs to ultrahigh-concentration multistage configurations is covered. Table of Contents: Introduction / CPCs / Practical Design of CPC Thermal Collectors / Practical Design of CPC PV Concentrators / Two-Stage Nonimaging Concentrators for Solar Thermal Applications / Two-Stage Nonimaging Concentrators for Solar PV Applications / Selected Demonstrations of Nonimaging Concentrator Performance / The Importance of Economic Factors in Effective Solar Concentrator Design / Ultrahigh Concentration / Bibliography

  • DIGITAL PROCESSING TECHNIQUES APPLIED TO POWER ELECTRONICS

    This chapter focuses on digital processing techniques and addresses basic algorithms, such as integral calculation, moving average filter (MAF), and RMS. It discusses digital filters for the identification of fundamental and symmetrical components, for example, positive and negative sequences. The chapter describes synchronization algorithms applied to single??? and three???phase systems and explores digital techniques for distributed generation systems, such as maximum power point tracking (MPPT) and islanding detection techniques. Digital synchronization algorithms are used in power electronic industry and applications, as for example, in grid???connected distributed generation systems. MPPT algorithms are very important in power conditioning of renewable energy resources, such as photovoltaic (PV) sources, since there is a unique point on the current???voltage (I???V) characteristic curve that corresponds to the MPP. The basic signal processing techniques are important tools to assist the implementation of simple functions, for example, average values, and active power calculation such as digital filters, frequency detector, and power electronic controllers.

  • MODELING ALTERNATIVE SOURCES OF ENERGY

    A detailed simulation of small power plants may be a very cost???effective solution, and very often several subsystems of a power plant might be inappropriate, difficult to find, or very expensive, like photovoltaic (PV) panels and fuel cells. This chapter discusses the most usual small electrical power plants such as wind, photovoltaic, fuel cells, and primary movers associated with batteries. It describes a model of a permanent magnet synchronous generator (PMSG) which is mechanically connected to a wind power turbine. In order to design integrated battery???based power electronics, a very good battery behavioral model is required which may include several parameters like state of charge (SOC), internal pressure, and so on. The current point of the SOC curve is estimated in order to be used as input information for a decision maker that is integrated with the energy management control of the renewable energy source used in the grid connected or stand???alone system.

  • Background and Current Status

    Significant research efforts are underway to develop commercially viable, technically feasible, highly efficient, and highly reliable power converters for renewable energy, electric transportation, and various industrial applications. This chapter presents state-of-the-art knowledge and cutting- edge techniques in various stages of research related to impedance source converters/inverters, including the concepts, advantages compared to existing technology, classification, current status, and future trends. Electric power generation comprises traditional power generation, such as hydroelectric, thermal and nuclear power production, and renewable energy sources, which already has a large penetration joined by photovoltaic (PV) and wind energy. In applications that need to boost the voltage, the Z-source converter is a possibility. Power electronics is the enabling technology for the energy processing necessary for electronic and electrical equipment of all types, from renewable energy to power systems, from house appliances to aerospace systems. New power electronic devices, such as the SiC and GaN, will definitely improve the Z-source converters performance.
