Voltage-Sourced Converters in Power Systems
Presents Fundamentals of Modeling, Analysis, and Control of Electric Power Converters for Power System ApplicationsElectronic (static) power conversion has gained widespread acceptance in power systems applications; electronic power converters are increasingly employed for power conversion and conditioning, compensation, and active filtering. This book presents the fundamentals for analysis and control of a specific class of high-power electronic converters—the three-phase voltage-sourced converter (VSC). Voltage-Sourced Converters in Power Systems provides a necessary and unprecedented link between the principles of operation and the applications of voltage-sourced converters. The book: Describes various functions that the VSC can perform in electric power systems Covers a wide range of applications of the VSC in electric power systems—including wind power conversion systems Adopts a systematic approach to the modeling and control design problems Illustrates the control design procedures and expected performance based on a comprehensive set of examples and digital computer time-domain simulation studiesThis comprehensive text presents effective techniques for mathematical modeling and control design, and helps readers understand the procedures and analysis steps. Detailed simulation case studies are included to highlight the salient points and verify the designs. Voltage-Sourced Converters in Power Systems is an ideal reference for senior undergraduate and graduate students in power engineering programs, practicing engineers who deal with grid integration and operation of distributed energy resource units, design engineers, and researchers in the area of electric power generation, transmission, distribution, and utilization.

Power Quality in Power Systems and Electrical Machines
Power quality of power systems affects all connected electrical and electronic equipment. Power quality is a measure of deviations in voltage and frequency of the particular supply system. In recent years, there has been a considerable increase in nonlinear loads; in particular distributed loads, such as computers, TV monitors and lighting. These draw harmonic currents which, when distorted, have detrimental effects including interference, loss of reliability, increased operating costs, equipment overheating, motor failures, capacitor failure and inaccurate power metering. This subject is pertinent to engineers involved with electric power systems, electronic equipment, computers and manufacturing equipment. This book shows readers to understand the causes and effects of power quality problems such as non-sinusoidal wave shapes, voltage outages, losses due to poor power quality, and origins of single-time events such as voltage dips, voltage reductions and outages, along with techniques to mitigate these problems.

Comprehensive review of generation and transmission expansion planning
Investment on generation system and transmission network is an important issue in power systems, and investment reversibility closely depends on performing an optimal planning. In this regard, generation expansion planning (GEP) and transmission expansion planning (TEP) have been presented by researchers to manage an optimal planning on generation and transmission systems. In recent years, a large number of research works have been carried out on GEP and TEP. These problems have been investigated with different views, methods, constraints and objectives. The evaluation of researches in these fields and categorising their different aspects are necessary to manage further works. This study presents a comprehensive review of GEP and TEP problems from different aspects and views such as modelling, solving methods, reliability, distributed generation, electricity market, uncertainties, line congestion, reactive power planning, demand-side management and so on. The review results provide a comprehensive background to find out further ideas in these fields.

Power electronics and control techniques for maximum energy harvesting in photovoltaic systems
\"Preface Photovoltaic (PV) systems are nowadays producing a significant amount of the electrical energy used all around the world. The support the PV technology can offer in the next decades, to the rate of growth of the advanced economies as well as of the developing Countries, is very high. The incentives provided at a first stage by the European governments have resulted in the rapid growth of the photovoltaic market and in the increase of the number and quality of products offered by the industries. PV modules by many producers are nowadays commercially available and a number of power electronic systems have been put on the Market for processing the electric power produced by PV systems, especially for grid connected applications. Also the scientific literature concerning PV applications has been characterized by a strong quantitative and qualitative growth in the last decade. A huge number of papers has been written and continues to be published in many journals; moreover, high impact factor scientific journals which are specifically devoted to photovoltaic systems are printed. A significant number of scientific papers is dedicated to the control of the photovoltaic source. A simple search on the Reuters Thomson website reveals that, at the end of May 2012, about 600 papers include the Maximum Power Point Tracking among their keywords. Many authors have contributed to the scientific field of the circuits and systems ensuring the best operation of the photovoltaic generator, but a reference in this field is still lacking. Some books that try to assess the most significant improvements concerning the connection of the photovoltaic systems to the grid have been recently published\"-- Provided by publisher.
