This book provides a systematic introduction to power system sub/super-synchronous oscillations caused by grid-connected wind power generation. The authors look at why oscillations occur and present methods for examining the risk of oscillations. Coverage includes state-space model based analysis and impedance model based analysis, which are the two main methods for examining the power system sub/super-synchronous oscillations. In addition, new methods for examining oscillations in wind farms are proposed. Analysis of Power System Sub/Super-Synchronous Oscillations Caused by Grid-connected Wind Power Generation provides researchers and students with a single-volume introduction to the subject and will be a valuable professional reference for practicing engineers looking for solutions to oscillation problems.

Wind power penetration is rapidly increasing in today's energy generation industry. In particular, the doubly-fed induction generator (DFIG) has become a very popular option in wind farms, due to its cost advantage compared with fully rated converter-based systems. Wind farms are frequently located in remote areas, far from the bulk of electric power users, and require long transmission lines to connect to the grid. Series capacitive compensation of DFIG-based wind farm is an economical way to increase the power transfer capability of the transmission line connecting the wind farm to the grid. For example, a study performed by ABB reveals that increasing the power transfer capability of an existing transmission line from 1300 MW to 2000 MW using series compensation is 90% less expensive than building a new transmission line. However, a factor hindering the extensive use of series capacitive compensation is the potential risk of subsynchronous resonance (SSR). The SSR is a condition where the wind farm exchanges energy with the electric network, to which it is connected, at one or more natural frequencies of the electric or mechanical part of the combined system, comprising the wind farm and the network, and the frequency of the exchanged energy is below the fundamental frequency of the system. This oscillatory phenomenon may cause severe damage in the wind farm, if not prevented. Therefore, this book studies the SSR phenomenon in a capacitive series compensated wind farm. A DFIG-based wind farm, which is connected to a series compensated transmission line, is considered as a case study. The book consists of two main parts: Small-signal modeling of DFIG for SSR analysis: This part presents a step-by-step tutorial on modal analysis of a DFIG-based series compensated wind farm using Matlab/Simulink. The model of the system includes wind turbine aerodynamics, a 6th order induction generator, a 2nd order two-mass shaft system, a 4th order series compensated transmission line, a 4th order rotor-side converter (RSC) controller and a 4th order grid-side converter (GSC) controller, and a 1st order DC-link model. The relevant modes are identified using participation factor analysis. Definition of the SSR in DFIG-based wind farms: This part mainly focuses on the identification and definition of the main types of SSR that occur in DFIG wind farms, namely: (1) induction generator effect (SSIGE), (2) torsional interactions (SSTI), and (3) control interactions (SSCI).

This book reviews and examines how power system low-frequency power oscillations and sub-synchronous oscillations may be affected by grid connection of wind power generation. Grid connection of wind power generation affects the power system small-signal stability and has been one of the most actively pursued research subjects in power systems and power electronics engineering in the last ten years. This book is the first of its kind to cover the impact of wind power generation on power system low-frequency oscillations and sub-synchronous oscillations. It begins with a comprehensive overview of the subject and progresses to modeling of power systems and introduces the application of conventional methods, including damping torque analysis, modal analysis and frequency-domain analysis, presented with detailed examples, making it useful for researchers and engineers worldwide.

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.
