Electrical Power System Essentials delivers a thorough introduction to the electrical power system and its functioning, and the changes that come with the worldwide energy transition process. This revised and updated Third Edition includes new material on HVDC developments, electricity markets, capacity calculation (NTC and flow-based), power system protection, and energy storage. Discussions on how renewable sources play a more dominant role in the generation of electrical energy and the effects they have on the control and operation of the grid and electricity markets are also included.
Written in the accessible style that has made previous editions so popular with readers, this book restricts math content to the Appendix in order to maintain an easy reading experience of the main text while still providing complete coverage. A companion website includes downloadable teaching materials and accessory videos are viewable on the Wiley website and YouTube.
Topics discussed in the book include: - Generation of electric energy, covering nuclear fission, wind energy and wind turbine concepts, hydropower and pumped storage, and solar power - Electricity markets, covering gas scarcity, its influence on the marginal price of electricity, and negative energy prices - Future power systems, covering higher harmonics, increased use of cables instead of overhead transmission lines, distributed generation and power-electronic interfaces - Transmission of electric energy, covering DC circuit breakers, wide area measurement systems, and distribution networks
Electrical Power System Essentials is a perfect textbook for second- and third-year undergraduate electrical engineering students who need an accessible course text introducing concepts in power system engineering. The text is also valuable for other students and professionals who require an up-to-date reference on power systems technology.
