Power engineering is the subfield of energy engineering that deals with production, transmission and utilization of electrical energy. Energy engineering on the other hand is the amalgamation of mathematics, chemistry, classical and modern physics. Both of these deal with efficient utilization of energy, facility management and energy services. Some of the topics discussed in this book are power generation, power system management, power transmission and distribution, smart grid technologies, etc. This book is compiled in such a manner, that it will provide in-depth knowledge about the theory and practice of power and energy engineering. It will serve as a valuable source of reference for graduate and post graduate students.
