Power systems are evolving towards the Smart Grid paradigm, featured by large-scale integration of renewable energy resources, e.g. wind and solar power, deeper participation of demand side, and enhanced interaction with electric vehicles. While these emerging elements are inherently stochastic in nature, they are creating a challenge to the system's stability and its control. In this context, conventional analysis tools are becoming less effective, and necessitate the use alternative tools that are able to deal with the high uncertainty and variability in the smart grid. Smart Grid initiatives have facilitated wide-spread deployment of advanced sensing and communication infrastructure, e.g. phasor measurement units at grid level and smart meters at household level, which collect tremendous amount of data in various time and space scales. How to fully utilize the data and extract useful knowledge from them, is of great importance and value to support the advanced stability assessment and control of the smart grid. The intelligent system strategy has been identified as an effective approach to meet the above needs. This book presents the cutting-edge intelligent system techniques and their applications for stability assessment and control of power systems. The major topics covered in this book are: Intelligent system design and algorithms for on-line stability assessment, which aims to use steady-state operating variables to achieve fast stability assessment for credible contingencies. Intelligent system design and algorithms for preventive stability control, which aims at transparent and interpretable decision-making on preventive control actions to manipulate system operating condition against possible contingencies. Intelligent system design and algorithms for real-time stability prediction, which aims to use synchronized measurements to foresee the stability status under an ongoing disturbance. Intelligent system design and algorithms for emergency stability control, which aims at fast decision-making on stability control actions at emergency stage where instability is propagating. Methodologies and algorithms for improving the robustness of intelligent systems against missing-data issues. This book is a reference and guide for researchers, students, and engineers who seek to study and design intelligent systems to resolve stability assessment and control problems in the smart grid age.

Comprehensive treatment of an aspect of stability constrained operations and planning, including the latest research and engineering practices Stability-Constrained Optimization for Modern Power System Operation and Planning focuses on the subject of power system stability, addressing a common gap in knowledge by presenting a series of stability-constrained optimization methodologies for power system operation and planning with the aim of power system stability enhancement. Unlike other resources, which focus mainly on the dynamic modeling, stability analysis, and controller design of power systems, this book is instead dedicated to operational and planning methods for power system stability enhancement, including power system stability preliminaries, stability-constrained operational dispatch, and stability-constrained network reinforcement planning. Authored by experts with established track records in both research and industry, Stability-Constrained Optimization for Modern Power System Operation and Planning covers sample topics such as: The definition, classification, and phenomenon of power system stability, recent large-scale blackouts in the world, and mathematical models and analysis tools for power system stability assessment Transient stability-constrained optimal power flow (TSC-OPF), hybrid solution methods for TSC-OPF, data-driven solution methods for TSC-OPF, and transient stability constrained-unit commitment (TSC-UC) TSC-OPF under wind power uncertainties, trajectory sensitivity-based preventive dispatch, preventive-corrective coordinated TSC-OPF, and optimal event-based load shedding Voltage stability indies, dynamic VAR resources (STATCOM and SVC), candidate bus selection for dynamic VAR allocation, and multi-objective dynamic VAR planning Stability-Constrained Optimization for Modern Power System Operation and Planning provides the latest research findings to scholars, researchers, and postgraduate students who are seeking optimization model formulations and solution methodologies for stability enhancement. It also provides key practical operational dispatch and network reinforcement planning methods to power system operators, planners, and decision-makers in the power utilities and related industries.

This reference and handbook describes theory, algorithms and applications of the Global Positioning System (GPS/Glonass/Galileo/Compass). It is primarily based on source-code descriptions of the KSGsoft program developed at the GFZ in Potsdam. The theory and algorithms are extended and verified for a new development of a multi-functional GPS/Galileo software. Besides the concepts such as the unified GPS data processing method, the diagonalisation algorithm, the adaptive Kalman filter, the general ambiguity search criteria, and the algebraic solution of variation equation reported in the first edition, the equivalence theorem of the GPS algorithms, the independent parameterisation method, and the alternative solar radiation model reported in the second edition, the modernisation of the GNSS system, the new development of the theory and algorithms, and research in broad applications are supplemented in this new edition. Mathematically rigorous, the book begins with the introduction, the basics of coordinate and time systems and satellite orbits, as well as GPS observables, and deals with topics such as physical influences, observation equations and their parameterisation, adjustment and filtering, ambiguity resolution, software development and data processing and the determination of perturbed orbits.

This book develops a dynamical model of the orbital motion of Lorentz spacecraft in both unperturbed and J2-perturbed environments. It explicitly discusses three kinds of typical space missions involving relative orbital control: spacecraft hovering, rendezvous, and formation flying. Subsequently, it puts forward designs for both open-loop and closed-loop control schemes propelled or augmented by the geomagnetic Lorentz force. These control schemes are entirely novel and represent a significantly departure from previous approaches.

Modern Inorganic Synthetic Chemistry, Second Edition captures, in five distinct sections, the latest advancements in inorganic synthetic chemistry, providing materials chemists, chemical engineers, and materials scientists with a valuable reference source to help them advance their research efforts and achieve breakthroughs. Section one includes six chapters centering on synthetic chemistry under specific conditions, such as high-temperature, low-temperature and cryogenic, hydrothermal and solvothermal, high-pressure, photochemical and fusion conditions. Section two focuses on the synthesis and related chemistry problems of highly distinct categories of inorganic compounds, including superheavy elements, coordination compounds and coordination polymers, cluster compounds, organometallic compounds, inorganic polymers, and nonstoichiometric compounds. Section three elaborates on the synthetic chemistry of five important classes of inorganic functional materials, namely, ordered porous materials, carbon materials, advanced ceramic materials, host-guest materials, and hierarchically structured materials. Section four consists of four chapters where the synthesis of functional inorganic aggregates is discussed, giving special attention to the growth of single crystals, assembly of nanomaterials, and preparation of amorphous materials and membranes. The new edition's biggest highlight is Section five where the frontier in inorganic synthetic chemistry is reviewed by focusing on biomimetic synthesis and rationally designed synthesis.

The core concern of this book is the potential use of taxation and related measures to foster climate-helpful, large-scale change within East Asia. The contributing authors examine key cases such as how Greater China, for instance, confronts severe environmental problems which are a direct product of several decades of remarkable economic growth. The detailed analysis in this book identifies a range of green taxation guidelines for East Asia as it seeks to drive down striking levels of environmental degradation - and address the climate change challenge. Addressing an important need in the public policy debate, this book will appeal to academics, students, government policy makers, regulators and practitioners in environmental law, taxation law and policy, as well as, comparative environmental law and comparative taxation law and policy. Public policy commentators and journalists with an interest in the above areas will also find this book worthwhile and informative. Contributors include: A. Cockfield, M. Derlen, S. Griffiths, W. Gumley, J. Lindholm, J. Milne, S. Phua, N. Stoianoff, J. Vanderwolk, Y. Xu

Coordination of Distributed Energy Resources in Microgrids: Optimisation, control, and hardware-in-the-loop validation provides a structured overview of research into techniques for managing microgrids with distributed energy resources (DERs). The DERs including distributed generators, energy storage systems, and flexible loads are posing both challenges and opportunities to microgrids' security, planning, operation, and control. Advanced operation and control techniques are needed to coordinate these components in the microgrids and maintain power quality, as well as keeping the system economically feasible. This book is for researchers and students in the area of smart grids, power engineering, and control engineering, as well as for advanced students, transmission network and grid operators. It focuses on cutting-edge techniques for secure, economic, and robust operation and control of microgrids. Effective coordination of DERs on both temporal and spatial scales are introduced in detail. Topics covered include comprehensive mathematical models of DERs and microgrids, sizing and siting of DERs under uncertainties, stochastic and robust optimisation for active and reactive power dispatch of DERs in microgrids, distributed coordinated control, and hardware-in-the-loop tests for validation of control algorithms.

The Young Men's Christian Association (YMCA) is best known for its athletic and youth programs, a heritage that draws on its origins in 1844 to provide wholesome recreation to urban youth away from the moral decay of industrialized urban living. Before long, that uplift mission found a place in the American Civil War, and soon the Y had spread all over the world by the early twentieth century, and in every major war thereafter as well. The YMCA at War: Collaboration and Conflict during the World Wars is the first collection of scholarship to examine the YMCA's efforts during the World Wars of the twentieth century, which proved to be a bastion of support to soldiers and civilians around the world. The YMCA deployed hundreds of thousands of its much-vaunted secretaries to support suffering civilians and ease soldiers' wartime hardships. Joining forces with governments, other civic organizations, and individuals, the Y could be either an indispensable auxiliary or an arms-length nuisance. In all cases, its support had a significant byproduct: for every person it befriended, the Y invariably made an enemy with an opposing party, its patrons, its sponsor, or at times, all three. The YMCA at War offers fresh, timely research in an international and comparative perspective from scholars around the world that evaluates this conflict and collaboration during the World Wars.
