Modeling and Stability Analysis of Inverter-Based Resources

Renewable energy sources interface with the ac grids via inverters and are termed inverter-based resources (IBRs). They are replacing traditional fossil fuel based synchronous generators with a dazzling speed. In turn, unprecedented dynamic events have occurred, threatening power grid reliability. This book provides a fundamental understanding of IBR dynamics.

Developing reliability solutions requires a thorough understanding of the challenges, in this case, IBR associated dynamics. Modeling and stability analysis play an indispensable role in revealing mechanism of dynamics. This book covers the essential techniques of dynamic model building for IBRs, including type-3 wind farms, type-4 wind farms, and solar photovoltaics. Besides modeling, this book offers readers the techniques of stability analysis. The book includes three parts. Part 1 focuses on tools, including electromagnetic transient simulation, analysis, and measurement-based modeling. Part 2 focuses on IBR modeling and analysis details. Part 3 is on generalized dynamic circuit representation--a unified modeling framework for dynamic and harmonic analysis.

This topic, IBR dynamic modeling and stability analysis, is interesting, challenging, and intriguing. The authors have led the effort of publishing the IEEE Power and Energy Society's TR-80 taskforce report "Wind Energy Systems Subsynchronous Oscillations: Modeling and Events" in July 2020, and the two taskforce papers on investigation of real-world IBR dynamic events. In this book, the authors share with the readers many insights in modeling and analysis for real-world IBR dynamic events investigation.
