Comprehensive reference exploring fundamentals of power systems analysis and operation through a unique blend of traditional and modern concepts Modern Power System explains the fundamentals of power systems analysis and operation, the latest developments with regard to transformation of energy sources from the conventional synchronous generators to the inverter-based sources, and the techniques and hardware used for this purpose. The book includes information on traditional power system concepts such as load flow, fault studies, protection, and stability as well as modern concepts including reactive power control, Flexible AC Transmission Systems (FACTS), HVDC transmission, renewable energy, and smart grids. Readers will find insights on topics such as phasor measurement unit (PMUs), wide-area measurements and control, and SCADA systems as well as distribution side aspects such as smart meters, demand management, and energy trading. Readers will also learn about point-to-point HVDC transmission using line commutated converters and multiterminal HVDC transmission. Additional topics discussed in include: Power system components such as transmission line parameters, transformer models, per-unit representation, and modeling of transmission linesEconomic operation of power plants and systems, with information on unit commitment and automatic generation controlPower system protection through instrument transformers, protective relays, and overcurrent relay coordinationReactive power compensation, covering voltage stability and ideal reactive compensationWater, solar, wind, hydrogen, and nuclear fusion as alternative energy sourcesModern Power System is an excellent textbook for undergraduate and graduate students in electrical engineering with a power engineering specialization, as well as practicing power system engineers seeking to keep up with the latest developments in the field.
