Research and education in power system dynamics

Lectures on power system dynamics
  1. This lecture is a short introduction to power system dynamics. It discusses the approximation of time-varying phasors, and reviews key aspects of the primary and secondary control methods.
  2. This lecture introduces the Direct-Quadrature-Zero (DQ0) transformation, shows how to use it to analyze linear networks, and discusses the relations between dq0 quantities and phasors.
  3. This lecture presents a dynamic model of the synchronous machine. We demonstrate how to use this model in power system simulations, and explain the relations between the machine's dq0 model and time-varying phasor model.
  4. This lecture focuses on management and control of energy storage devices. We explain how these devices are used for energy balancing, load leveling, peak shaving, and energy trading.
Homework Assignments: Assignment 1, Assignment 2, Assignment 3, Assignment 4, Research Assignment.
Software

This is a free software tool for analyzing the dynamics of power systems based on dq0 signals. It is designed to simulate and analyze power systems that include several generators and loads, and possibly a large transmission network. The software provides tools for constructing dynamic models of the system components, and enables analysis in the frequency domain or the time domain. The manual (including tutorial) and software provide simple explanations and examples that can help one get started.

This software package supports:

  • Dynamic analysis of large-scale networks.
  • Simulation of complete networks.
  • Transient simulations.
  • Small-signal analysis.

To get started,

  1. Download the software files from MATLAB Central, and copy them to a directory of your choice, e.g., C:\DQ0 dynamics.
  2. Setup the directory in your MATLAB path. In the MATLAB, go to File > Set Path... and click on Add with Subfolders.... Now, select the directory that contains the DQ0 dynamics folder.
  3. Save the path for future MATLAB sessions (usually administrator privileges are necessary).
  4. For more advanced installation options please see the MANUAL.
