This book provides modeling, analysis, and control methods for wideband oscillations caused by control interactions in converter-dominated power systems. The modern power system comprises power electronic devices in various forms, including wind turbines, photovoltaics, flexible AC/DC transmission systems, battery energy storage systems, and distributed generations, among others. Unstable oscillation modes can cause equipment damage, sudden power reduction, noise in power transformers, and degradation of power quality. Wideband oscillation seriously threatens the stable and reliable operation of wind power systems. The interaction mechanism becomes more complex due to system-wide factors such as network topology, grid strength, input resource intermittency, converter control parameters, and the output levels of renewable generators. This complexity presents a significant challenge in studying the intricate control interaction phenomena and deriving appropriate countermeasures. The book is beneficial for industry professionals, engineers, and academic researchers working on power systems in general, and specifically on power electronic converters.

This book provides an overview of power electronic converters for numerical simulations based on DIgSILENT PowerFactory. It covers the working principles, key assumptions and implementation of models of different types of these power systems. The book is divided into three main parts: the first discusses high-voltage direct currents, while the second part examines distribution systems and micro-grids. Lastly, the third addresses the equipment and technologies used in modelling and simulation. Each chapter includes practical examples and exercises, and the accompanying software illustrates essential models, principles and performance using DIgSILENT PowerFactory. Exploring various current topics in the field of modelling power systems, this book will appeal to a variety of readers, ranging from students to practitioners.

This book covers modeling, control and stability aspects of hybrid AC/DC power networks. More specifically, this book provides an in-depth analysis of the stability and control aspects of hybrid AC/DC power grids, with comprehensive coverage of theoretical aspects of conventional stability issues (e.g., small-signal stability, voltage stability and frequency stability), emerging stability issues (e.g., converter associated stability) and control strategies applied in this emerging hybrid AC/DC power grids. This book takes a more pragmatic approach with a unique compilation of timely topics related to hybrid AC/DC networks compared with other books in this field. Therefore, this book provides the reader with comprehensive information on modeling, control and stability aspects which need to consider when modeling and analysis of hybrid AC/DC power grids for power system dynamics and stability studies. Each chapter provides fundamental stability theories, some worked examples and case studies to explain various modeling, analysis and control concepts introduced in the chapter. Therefore, postgraduate research students, power system researchers and power system engineers benefit from the materials presented in this book and assist them to model and device new control strategies to overcome the stability challenges of the emerging hybrid AC/DC power grid.

A thorough and exhaustive presentation of theoretical analysis and practical techniques for the small-signal analysis and control of large modern electric power systems as well as an assessment of their stability and damping performance.
