21st Century Power Systems Dynamics

Overview

The objective of this course is to learn some fundamentals as well as state of the art in modeling and control of low inertia systems

• This means going into "classic" textbooks on dynamics
• ...as well as getting some fundamentals on inverters under our belts
• ...and reading a select group of papers

Format

We will balance lectures on fundamentals -- drawn from textbooks -- with paper presentations and discussion. The key deliverables will be group work building simulation models that reproduce and extend papers from the literature.

Materials

We will use two textbooks. Both are available through the library but also on the bCourses page for this course.

• Machowski, Bialek and Bumby, "Power System Dynamics: Stability and Control" (2008; 2nd ed). (MBB in the table below)
• Yazdani and Iravani, "Voltage-Sourced Converters in Power Systems: Modeling, Control, and Applications" (2010). (YI in table below)
