We have written this book in the hope that the following engineers, or potential engineers, will benefit from it:

• Recent graduates in electrical engineering who need to understand the tools and techniques currently available in the analysis of small-signal dynamic performance and design.
• Practicing electrical engineers who need to understand the significance of more recent developments and techniques in the field of small-signal dynamic performance.
• Postgraduate students in electrical engineering who need to understand current developments in the field and the need to orient their research to achieve practical, useful outcomes.
• Undergraduate electrical engineering students in courses oriented towards electric power engineering in which there is an introductory subject in power system dynamics (for access to basic material).
• Managerial staff with responsibilities in power system planning, and system stability and control.

An aim of the book is to provide a bridge between the mathematical/theoretical and physical/practical significance to the topic. Some of the fundamental background relevant to the main topics of the book is presented in the early chapters so that the necessary material is readily available to the reader in the one book.
