ESE 576: Power System Dynamics

Course description

The course provides the background for understanding power system dynamics and numerical simulation techniques.
The main topics include the numerical integration for large scale power networks, numerical oscillation and its solution, power system component modeling, frequency-dependent transmission network, nonlinear elements, network equivalents, power network stability, simulation of power electronic inverters, and microgrid stability & control.
The area of real-time simulation for cyber-physical power infrastructures will also be discussed.
