Power system oscillations are a critical aspect of power system stability and control. This book provides a comprehensive overview of the topic, covering various aspects of power system oscillations, including modal analysis, control strategies, and the impact of system structure on oscillatory behavior. The book is divided into several chapters, each focusing on different aspects of power system oscillations. The first chapter introduces the nature of power system oscillations, while the second chapter discusses the classical generator model and its modes of oscillation. The third chapter presents a detailed generator model, and the fourth chapter explores the response of the system to faults. The fifth chapter provides a final discussion and comments on the classical and detailed generator models. The book also covers modal analysis of power systems, including the analysis of linear dynamic systems, eigenvectors, eigenvalue sensitivity, and the application of modal analysis to detailed generator cases with and without controls. The chapter on modal analysis for control discusses transfer functions, controllability, observability, residues, frequency response, and the synchronization and damping torques in power systems. The book further explores the structure of power systems and the influence of tie lines on inter-area mode stability. It discusses generator controls, including speed governor controls and excitation controls, and the design and evaluation of power system stabilizers. The book also addresses the problems and solutions related to power system stabilizers, robust control strategies, and the damping of oscillations using electronic power system devices such as static VAr compensators and thyristor controlled series capacitors. The final chapters of the book discuss high voltage DC link modulation, general comments on damping control, and provide model data formats and block diagrams for various power system components. The book concludes with an index for easy reference. Overall, this book is a valuable resource for engineers and researchers working in the field of power systems, providing a detailed understanding of power system oscillations and their control.Power system oscillations are a critical aspect of power system stability and control.
