• Introduction.- Coherency in Power Systems.- Slow Coherency and Aggregation.- Excitation System Aggregation.- A Hybrid Dynamic Equivalent using ANN-based BoundaryMatching Technique.- Krylov Subspace and Balanced Truncation Methods for Power System Model Reduction.- Reduction of Large Power System Models: A Case Study.- Measurement-based Methods for Model Reduction of Power Systems using Synchrophasors.- Selective Modal Analysis.- InterareaMode Analysis for Large Power Systems using Synchrophasor Data.

From the reviews: "I enjoyed reading this monograph and would highly recommend it. It is an excellent reference providing an overview of power system coherency, model reduction, and related problems by integrating analytical bases, engineering practices, emerging techniques, and insights, which would benefit both engineers and researchers in the fields of power system dynamics.
