Interconnected Power Systems

This book reports on the latest findings in the application of the wide area measurement systems (WAMS) in the analysis and control of power systems. The book collects new research ideas and achievements including a delay-dependent robust design method, a wide area robust coordination strategy, a hybrid assessment and choice method for wide area signals, a free-weighting matrices method and its application, as well as the online identification methods for low-frequency oscillations. The main original research results of this book are a comprehensive summary of the authors' latest six-year study. The book will be of interest to academic researchers, R&D engineers and graduate students in power systems who wish to learn the core principles, methods, algorithms, and applications of the WAMS.

The first book to investigate the wide area dynamic monitoring and control of interconnected power systems Presents detailed control design programming on wide area robust coordination, delay-dependent robust stabilization, mixed robust control optimization, etc. Addresses detailed monitoring algorithms such as the improved Hilbert Huang Transform, relative phase calculation, and complex orthogonal decomposition Demonstrates a hardware-in-the-loop (HIL) simulation platform for testing various wide area monitoring and control methods Includes supplementary material: sn.pub/extras
