Comprehensive, state-of-the-art review of information on the electric power system dynamics and stability. It places the emphasis first on understanding the underlying physical principles before proceeding to more complex models and algorithms. The book explores the influence of classical sources of energy, wind farms and virtual power plants, power plants inertia and control strategy on power system stability. The book cover a range of new and expanded topics including: Wide-area monitoring and control systems; Improvement of power system stability by optimization of control systems parameters; Impact of renewable energy sources on power system dynamics; The role of power system stability in planning of power system operation and transmission network expansion; Real regulators of synchronous generators and field tests; Selectivity of power system protections at power swings in power system; Criteria for switching operations in transmission networks; Influence of automatic control of a tap changing step-up transformer on the power capability area of the generating unit; Mathematical models of power system components such as HVDC links, wind and photovoltaic power plants; Data of sample (benchmark) test systems.
