Robust Power System Frequency Control

Frequency control is an important control problem in electric power system design and operation, and is becoming more significant today due to the increasing size, changing structure, emerging new distributed renewable power sources and uncertainties, environmental constraints, and the complexity of power systems. In the last two decades, many studies have focused on damping control and voltage stability and the related issues, but there has been much less work on the power system frequency control analysis and synthesis. While some aspects of frequency control have been illustrated along with individual chapters, many conferences, and technical papers, a comprehensive and sensible practical explanation of robust frequency control in a book form encouraged author to provide the first edition of Robust Power System Frequency Control in 2009. Following numerous kind notes and valuable feedbacks from the worldwide readers and the publisher; as well as considering recent relevant challenges and developments, the author is pleased to present the 2nd revised edition. This updated edition of the industry standard reference on power system frequency control offers new solutions to the technical challenges introduced by the escalating role of distributed generation and renewable energy sources in modern electric grids. The role of frequency control loops (primary, secondary, tertiary and emergency) in modern power systems is explained. The impacts of low inertia and damping effect on system frequency in the presence of increased distributed and renewable power penetration are given particular consideration, as the bulk synchronous machines-based conventional frequency control are rendered ineffective in emerging grid environments where distributed/variable units with little or no rotating mass become dominant. Frequency stability and control issues relevant to the exciting new field of microgrids are also undertaken in this new edition.
