This advanced textbook explores representations of signals in electric energy systems (EES) and their applications in tasks such as protection, monitoring, estimation, and control. EES plays a crucial role in energy conversion at levels ranging from personal devices and vehicles, such as cars, airplanes, and ships, to regions and even whole continents. The text provides a unified modeling framework for consistent EES analysis, design, and integration with physical and cyber environments. It includes tools that enable frequency-selective modeling, simulation, and control. In modern EES, the switching mode of operation introduces multiple frequency components in signals, and the book's modeling concepts help quantify the dynamics of harmonics in power networks. Coverage includes power electronic converters, electric machines and drives, and other power system components. One of the book's main focuses is characterizing EES transients, which is of significant engineering interest, especially for emerging control and protection strategies that utilize signal processing and microcontrollers. 
Dynamics Phasors in Energy Processing Systems is appropriate for graduate and advanced undergraduate courses in electric energy engineering and is a valuable professional resource for researchers and practitioners in industry, academia, and national laboratories.
