This book covers the digitalization of the grid from a practical point of view and helps you understand the principles used in the development of the standard and its multiple benefits of how they can help in all aspects of the specialists’ everyday work. The book demonstrates that the IEC 61850 standard is a new communications protocol and a completely new engineering environment using named data objects and attributes that support the interoperability between multifunctional devices from different manufacturers integrated in protection automation and control systems. It highlights the contribution of the standard in introducing high speed peer to peer communications that support different substation and wide area protection and automation related applications. You will be introduced to the different parts of the standard and their evolution from a substation centered approach towards its expansion targeting the coverage of the different domains of the smart grid. It approaches the subject from a practical point utilizing an expert’s years of experience. It provides numerous examples of the application of the standard for protection, automation, and control in smart grid. This is an excellent resource for utility specialists and researchers developing protection, automation and control devices in systems based on the standard; and by consultants helping with the implementation of the standard in different projects.

This book introduces several battery management problems and provides solutions using model-based approaches. It provides detailed coverage of battery management problems, including battery impedance estimation, battery capacity estimation, state of charge estimation, state of health estimation, battery thermal management, and optimal charging algorithms. The book introduces important battery management problems in a modularized fashion, decoupling each battery management problem from others as much as possible, allowing you to focus on understanding a particular topic rather than having to understand all aspects of a battery management system. You will get the necessary background to understand, implement and improve battery fuel gauges in electric vehicles, and general state of health of the battery; use proven models and algorithms to estimate the thermal properties of a battery; and know the basics of smart battery charger design. You will also be equipped to accurately estimate battery features of vehicles, such as state of charge, expected charging time, and state of health, to make customized charging waveforms for each vehicle. The book teaches you how to create simulation environments to test and validate algorithms against model uncertainty and measurement noise. In addition, the importance of benchmarking battery management algorithms is covered, and several bench marking metrics are presented. Included MATLAB codes give you an easy way to test the algorithms using realistic data and to develop and test alternative solutions. This is a useful and timely guide for battery engineers at all levels, as well as research scientists and advanced students working in this robust and rapidly advancing area.

Here is a timely resource that gives you an insightful business perspective on electric systems operations, revealing how this area is critical to a utility's ability to provide reliable power to its customers. The book presents a thorough definition system operations, identifying and explaining the various systems that support this function and how they integrate into the utility. You discover how a utility's network operation is a key contributor to the viable sustainment of its business. The book presents the convergence of the systems used in the grid operations of today and addresses the emerging needs of the smart grid operations of tomorrow. You learn how system operations help to ensure the right levels of safety, reliability and efficiency in everything that relates to transmission and distribution grid management. The book discusses important technologically intensive systems -- like EMS, DMS -- that function inside the control center. Additionally, you are introduced to DEMS -- an emerging system which has been designed to help utilities provide better services to customers, and enable customers to become an integral part of the overall utility system.

About the Book: Electrical power system together with Generation, Distribution and utilization of Electrical Energy by the same author cover almost six to seven courses offered by various universities under Electrical and Electronics Engineering curriculum. Also, this combination has proved highly successful for writing competitive examinations viz. UPSC, NTPC, National Power Grid, NHPC, etc.

This comprehensive overview of 61850 standard/protocol focuses on implementation, taking the reader through the development and concepts of IEC 61850. This includes the initial work by General Motors (Manufacturing Automation Protocol), EPRI (UCA 1.0 and UCA 2.0), IEEE (TR 1550), and IEC 61850. The standard is a significant piece of many IIoT (industrial internet of things) strategies for substation communication. The book discusses and documents the basic research and theory of guaranteed multicast done for IEC 61850 GOOSE as well as the shift from variable technology to object oriented technology. The layering principles, as well as the structure, of IEC 61850 are discussed in detail as well as the actual communication profiles that have been created to support substation/distribution automation, distributed energy resources, and synchrophasors. Real applications will be discussed as well as the future direction of the standard. The author is a technical co-editor of IEC 61850 standard and a leader in US implementations, having been involved with the technology from its inception.

In the development of telecommunication networks throughout the world, digital transmission has now replaced analog transmission as the predominant choice for new transmission facilities. This trend began in the early 1960s when the American Telephone and Telegraph Company first introduced pulse code modulation as a means of increasing capacity in their cable plant. Since that time, digital transmission applications have grown dramatically, notably in the United States, Canada, Japan, and Western Europe. With the rapidity of digital transmission developments and imple mentation, however, there has been a surprising lack of textbooks written on the subject. This book grew out of my work, research, and teaching in digital transmission systems. My objective is to provide an overview of the subject. To accomplish this end, theory has been blended with practice in order to illustrate how one applies theoretical principles to actual design and imple mentation. The book has abundant design examples and references to actual systems. These examples have been drawn from common carriers, manufac turers, and my own experience. Considerable effort has been made to include up-to-date standards, such as those published by the CCITT and CCIR, and to interpret their recommendations in the context of present-day digital transmission systems.
