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.

PROPOSAL FOR INTEGRATION OF PHOTOVOLTAIC AND THERMAL ENERGY SYSTEMS AS AN ELECTRIC MACROSYSTEM OF THE STATE OF RORAIMA, BRAZIL
Theoretical Framework: The theoretical basis of this study is the fundamentals of thermoelectric and photovoltaic energy generation viewed from the perspective of systems theory. Integration conforms to the macrosystem, whose components are the two systems to be integrated, operating according to systemic principles: interdependence, equifinality, and homeostasis. Method: The methodology adopted for this research included a literature review (bibliographic research) in conjunction with the observation and analysis of the functioning of energy systems that operate separately. Results and Discussion: The results obtained revealed the possibility of integrating the systems. In the discussion section, these results are contextualized within the theoretical framework, highlighting the normative implications and relationships emanating from the regulatory agency. Possible adversities for execution may originate from the different voltage ranges that need to be made available to consumers. Research Implications: The practical and theoretical implications of this research are methodological, as the study presents the materials and procedures necessary for integrating systems, specified through an examination of the real situation in the state of Roraima. Originality/Value: This study contributes to the literature by presenting a systematic integration of energy generation systems that utilize both fossil fuels and renewable energies, in pursuit of a future with predominantly sustainable energy availability.
