Sustainability Performance Evaluation of Renewa...

This book presents a unique analysis of the sustainability performance of various renewable energy sources, based on Brazilian case studies. The evaluation also covers the potential held by regions with diverse socioeconomic and environmental characteristics and how they affect the development of each source. Considering that energy is essential to sustaining and improving modern society, the answer to the current energy dilemma lies in the development of a system that comprises multiple renewable, reliable, and sustainable energy sources. Brazil, which has a predominantly renewable electricity grid, has the privilege of being home to a range of different sustainable sources, although most of its electricity comes from hydroelectric power plants. With that in mind, this book has the primary objective of developing a performance evaluation system for important renewable sources in Brazil (solar, wind, and hydro), taking into account different scenarios and investor profiles. The analysis is based on the study of sustainability indicators related to the technical, economic, social and environmental aspects of the evaluated energy systems. As the availability of renewable sources is very location-specific, the scope of this book covers two Brazilian States with distinct characteristics. It makes it possible to determine which renewable energy source is most adequate from a sustainability perspective, and in light of the analyzed scope and investor profile.

An essential guide to the stability and control of power systems integrating large-scale renewable energy sources The rapid development of smart grids and the integration of large scale renewable energy have added daunting new layers of complexity to the long-standing problem of power system stability control. This book offers a systematic stochastic analysis of these nonlinear problems and provides comprehensive countermeasures to improve power system performance and control with large-scale, hybrid power systems. Power system stability analysis and control is by no means a new topic. But the integration of large scale renewable energy sources has added many new challenges which must be addressed, especially in the areas of time variance, time delay, and uncertainties. Robust, adaptive control strategies and countermeasures are the key to avoiding inadequate, excessive, or lost loads within hybrid power systems. Written by an internationally recognized innovator in the field this book describes the latest theory and methods for handling power system angle stability within power networks. Dr. Jing Ma analyzes and provides control strategies for large scale power systems and outlines state-of-the-art solutions to the entire range of challenges facing today´s power systems engineers. Features nonlinear, stochastic analysis of power system stability and control Offers proven countermeasures to optimizing power system performance Focuses on nonlinear time-variance, long time-delays, high uncertainties and comprehensive countermeasures Emphasizes methods for analyzing and addressing time variance and delay when integrating large-scale renewable energy Includes rigorous algorithms and simulations for the design of analysis and control modeling Power System Wide-area Stability Analysis and Control is must-reading for researchers studying power system stability analysis and control, engineers working on power system dynamics and stability, and graduate students in electrical engineering interested in the burgeoning field of smart, wide-area power systems.

Energy and the Wealth of Nations
67,99 € *

In this updated edition of a groundbreaking text, concepts such as energy return on investment (EROI) provide powerful insights into the real balance sheets that drive our ´´petroleum economy.´´ Hall and Klitgaard explore the relation between energy and the wealth explosion of the 20th century, and the interaction of internal limits to growth found in the investment process and rising inequality with the biophysical limits posed by finite energy resources. The authors focus attention on the failure of markets to recognize or efficiently allocate diminishing resources, the economic consequences of peak oil, the high cost and relatively low EROI of finding and exploiting new oil fields, including the much ballyhooed shale plays and oil sands, and whether alternative energy technologies such as wind and solar power can meet the minimum EROI requirements needed to run society as we know it. For the past 150 years, economics has been treated as a social science in which economies are modeled as a circular flow of income between producers and consumers. In this ´´perpetual motion´´ of interactions between firms that produce and households that consume, little or no accounting is given of the flow of energy and materials from the environment and back again. In the standard economic model, energy and matter are completely recycled in these transactions, and economic activity is seemingly exempt from the Second Law of Thermodynamics. As we enter the second half of the age of oil, when energy supplies and the environmental impacts of energy production and consumption are likely to constrain economic growth, this exemption should be considered illusory at best. This book is an essential read for all scientists and economists who have recognized the urgent need for a more scientific, empirical, and unified approach to economics in an energy-constrained world, and serves as an ideal teaching text for the growing number of courses, such as the authors´ own, on the role of energy in society.
