Book Description

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.

Book Description

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.

Book Description

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.

Book Description

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.

Book Description

Explore the theoretical foundations and real-world power system applications of convex programming In Mathematical Programming for Power System Operation with Applications in Python, Professor Alejandro Garces delivers a comprehensive overview of power system operations models with a focus on convex optimization models and their implementation in Python. Divided into two parts, the book begins with a theoretical analysis of convex optimization models before moving on to related applications in power systems operations. The author eschews concepts of topology and functional analysis found in more mathematically oriented books in favor of a more natural approach. Using this perspective, he presents recent applications of convex optimization in power system operations problems. Mathematical Programming for Power System Operation with Applications in Python uses Python and CVXPY as tools to solve power system optimization problems and includes models that can be solved with the presented framework. The book also includes: A thorough introduction to power system operation, including economic and environmental dispatch, optimal power flow, and hosting capacity Comprehensive explorations of the mathematical background of power system operation, including quadratic forms and norms and the basic theory of optimization Practical discussions of convex functions and convex sets, including affine and linear spaces, politopes, balls, and ellipsoids In-depth examinations of convex optimization, including global optimums, and first and second order conditions Perfect for undergraduate students with some knowledge in power systems analysis, generation, or distribution, Mathematical Programming for Power System Operation with Applications in Python is also an ideal resource for graduate students and engineers practicing in the area of power system optimization.

Book Description

Power system modelling and scripting is a quite general and ambitious title. Of course, to embrace all existing aspects of power system modelling would lead to an encyclopedia and would be likely an impossible task. Thus, the book focuses on a subset of power system models based on the following assumptions: (i) devices are modelled as a set of nonlinear differential algebraic equations, (ii) all alternate-current devices are operating in three-phase balanced fundamental frequency, and (iii) the time frame of the dynamics of interest ranges from tenths to tens of seconds. These assumptions basically restrict the analysis to transient stability phenomena and generator controls. The modelling step is not self-sufficient. Mathematical models have to be translated into computer programming code in order to be analyzed, understood and “experienced”. It is an object of the book to provide a general framework for a power system analysis software tool and hints for filling up this framework with versatile programming code. This book is for all students and researchers that are looking for a quick reference on power system models or need some guidelines for starting the challenging adventure of writing their own code.

Book Description

Heat and Fluid Flow in Power System Components is a collection of papers presented at the Second Conference on Mechanical Power Engineering held in Cairo, Egypt in September 1978. This volume covers a wide range of topics relating to heat and fluid flow in power system components, including film cooling, droplet evaporation, and laminar flames. Practical applications such as furnaces, heat exchanges, pumps, and turbines are also discussed. Results of investigations carried out experimentally, by computation, and both computation and experimentation techniques are presented. This book is comprised of 21 chapters and begins with an analysis of heat transfer in power elements, including evaporation of surface liquid droplet in an air stream. The thermal conductivity of granular materials is also examined. The following chapters explore reactive and non-reactive flows, paying particular attention to helium two-phase instabilities; air flow around hyperbolic cooling towers; pulsating flow in axial turbines; laminar flame propagation in tubes; and characteristics of combustion heat liberated downstream of circular bluff bodies. The final chapter is devoted to an experimental and theoretical investigation of the reversed flow furnace. This monograph will be of interest to chemical and mechanical engineers as well as researchers concerned with the design, development, and optimum modes of operations of power systems and their components.
