ECE 6354 Power System Dynamics and Control | ECE | Virginia Tech


Course Information


Dynamic modeling, stability analysis, and control of multi-machine power systems. Single-machine dynamic modeling, multi-machine dynamic modeling, network differential-algebraic equations and solution methods, small-signal stability analysis, and design of power system stabilizers.

Why take this course?

Operators and planners for electric power utilities routinely perform dynamic stability analysis to assess the stability margins of their power systems and take preventive actions in case these margins are insufficient. They also design controllers and protection schemes to enable their power systems to dampen instabilities and withstand disturbances. Therefore, it is essential that the students be exposed to these modeling and design tools. This course will expose them to various models, methodologies and simulation techniques for multi-machine systems and their controllers. This topic is not covered in other courses.
