Opis

With the growth of the installed capacity and the proportion of REG, mainly including wind power and PV power generation, the stable operation of REG and AC/DC transmission systems has become a technical bottleneck for the sustainable development of REG. Since 2009, broadband oscillation incidents have occurred frequently in REG and AC/DC transmission systems in China and some foreign countries, resulting in severe consequences such as large-scale tripping-off of REG units, damaging equipments, and an increasing curtailment of wind and PV power generation. However, there are great difficulties and challenges for the analysis and mitigation of broadband oscillation.This book focuses on the analysis and mitigation of broadband oscillation in renewable energy generation and AC/DC transmission systems. The theoretical knowledge and practical approaches to solve this issue are explored through the contents of 4 parts, 18 chapters. Part Ⅰ is Small-signal Modeling of Converters, containing four chapters. The frequency-domain small-signal modeling method and impedance modeling of three types of basic converters commonly used in power electronic devices, including the two-level converter, modular multilevel converter, and thyristor converter are introduced. Part Ⅱ is Impedance Model and Characteristics Analysis of REG and HVDC Transmission, containing six chapters. The impedance model and characteristics analysis of the full power conversion wind turbine, DFIG-based wind turbines, PV unit, SVG, LCC-HVDC, and MMC-HVDC are introduced. Part Ⅲ is Broadband Oscillation Analysis in REG and AC/DC Transmission Systems, containing three chapters. The impedance modeling and characteristics analysis of REG plants, and oscillation analysis of REG connected into AC and HVDC transmission systems are introduced. Part Ⅳ is Broadband Oscillation Mitigation in REG and AC/DC Transmission Systems, containing five chapters. The impedance reshaping of the REG unit, SVG, LCC-HVDC, and MMC-HVDC as well as project cases are presented.This book can be used by the researchers engaged in the design, technology research and development, and operation management of electrical engineering and renewable energy engineering, which can also be a reference book for teachers and students of electrical engineering in colleges and universities.

Weisheng Wang was born in 1968. He got his Ph.D degree from the School of Electrical Engineering, Xi'an Jiaotong University in 1996. He is currently the chief engineer of China Electric Power Research Institute Co., Ltd., professorate senior engineer, and doctoral supervisor. He has been engaged in the research of renewable energy generation, operation and control technology for more than twenty years. He and his team tackled a couple of the technical issues of large-scale renewable energy integration, including the cascading tripping-off of renewable energy generation units and the broadband oscillation incidents. They also developed a renewable energy power prediction and scheduling optimization system. He has led the building up of the Zhangbei Test Base, which is the world's largest field test base and the only one with the AC/DC grid-connected conditions and with all performance testing functions for renewable energy units. His research results have been widely applied, supporting the safe and stable operation and the efficient accommodation of large-scale renewable energy in China. He has won 3 second prizes of National Science and Technology Progress Award and 8 first prizes of the provincial and ministerial science and technology progress award. He has authorized 18 invention patents, 5 books, and more than 100 papers. He has supervised 28 postdoctoral, doctoral and master students.

This book is a translation of an original German edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.
