A major contribution to one of the central themes in social theory, this book integrates multiple case studies of the relationship between water control and social organization. Substantial in empirical detail and featuring powerful theoretical extensions, Scarborough's analysis encompasses early Harappan society in South Asia, highland Mexico, the Maya lowlands, north-central Sri Lanka, the prehistoric American Southwest, and Bronze Age Greece. This book is the first longitudinal study to consider water management worldwide since Karl Wittfogel put forth his "hydraulic societies" hypothesis nearly two generations ago, and it draws together the diverse debates that seminal work inspired. In so doing, Scarborough offers new models for cross-cultural analysis and prepares the ground for new examinations of power, centralization, and the economy.

Professor Emanuel uses clear presentation to compare and facilitate understanding of two seminal standards, The IEEE Std. 1459 and The DIN 40110-2:2002-11. Through critical analysis of the most important and recent theories and review of basic concepts, a highly accessible guide to the essence of the standards is presented. Key features: Explains the physical mechanism of energy flow under different conditions: single- and three-phase, sinusoidal and nonsinusoidal, balanced and unbalanced systems Starts at an elementary level and becomes more complex, with six core chapters and six appendices to clarify the mathematical aspects Discusses and recommends power definitions that played a significant historical role in paving the road for the two standards Provides a number of original unsolved problems at the end of each chapter Introduces a new nonactive power; the Randomness power. Power Definitions and the Physical Mechanism of Power Flow is useful for electrical engineers and consultants involved in energy and power quality. It is also helpful to engineers dealing with energy flow quantification, design and manufacturing of metering instrumentation; consultants working with regulations related to renewable energy courses and the smart grid; and electric utility planning and operation engineers dealing with energy bill structure. The text is also relevant to university researchers, professors, and advanced students in power systems, power quality and energy related courses.

This book discusses the major aspects of load flow, optimization, optimal load flow, and culminates in modern heuristic optimization techniques and evolutionary programming. In the deregulated environment, the economic provision of electrical power to consumers requires knowledge of maintaining a certain power quality and load flow. Many case studies and practical examples are included to emphasize real-world applications. The problems at the end of each chapter can be solved by hand calculations without having to use computer software. The appendices are devoted to calculations of line and cable constants, and solutions to the problems are included throughout the book.

This rigorous tutorial is aimed at both power system professionals and electrical engineering students. Breaking down the complexities of load flow analysis into a series of short, focused chapters, the book develops each of the major algorithms used, covers the handling of generators and transformers in the analysis process, and details how these algorithms can be deployed in powerful software. Having read the book, and EE student or engineer will have all the tools necessary to predict load usage and prevent overloads, blackouts, and brownouts.

Imagine feeling as though the world is working with you, not against you. Imagine a day in which you make every green light and slip effortlessly into a parking spot in the most crowded part of town. You make a To Do list, and the people on it call you first. You turn on the radio just in time to hear the exact information you need. These meaningful coincidences, called synchronicity, are sure signs you are "in the flow." Based on new, groundbreaking research, The Power of Flow goes beyond other books on synchronicity to provide you with sixteen easy-to-understand techniques that allow you to access this magical state of flow and create a richer, more satisfying life.

Power Flow Control Solutions for a Modern Grid using SMART Power Flow Controllers Provides students and practicing engineers with the foundation required to perform studies of power system networks and mitigate unique power flow problems Power Flow Control Solutions for a Modern Grid using SMART Power Flow Controllers is a clear and accessible introduction to power flow control in complex transmission systems. Starting with basic electrical engineering concepts and theory, the authors provide step-by-step explanations of the modeling techniques of various power flow controllers (PFCs), such as the voltage regulating transformer (VRT), the phase angle regulator (PAR), and the unified power flow controller (UPFC). The textbook covers the most up-to-date advancements in the Sen transformer (ST), including various forms of two-core designs and hybrid architectures for a wide variety of applications. Beginning with an overview of the origin and development of modern power flow controllers, the authors explain each topic in straightforward engineering terms—corroborating theory with relevant mathematics. Throughout the text, easy-to-understand chapters present characteristic equations of various power flow controllers, explain modeling in the Electromagnetic Transients Program (EMTP), compare transformer-based and mechanically-switched PFCs, discuss grid congestion and power flow limitations, and more. This comprehensive textbook: Describes why effective Power Flow Controllers should be viewed as impedance regulators Provides computer simulation codes of the various power flow controllers in the EMTP programming language Contains numerous worked examples and data cases to clarify complex issues Includes results from the simulation study of an actual network Features models based on the real-world experiences the authors, co-inventors of first-generation FACTS controllers Written by two acknowledged leaders in the field, Power Flow Control Solutions for a Modern Grid using SMART Power Flow Controllers is an ideal textbook for graduate students in electrical engineering, and a must-read for power engineering practitioners, regulators, and researchers.
