EE 5200 is the lead-off graduate course in Electrical Power Systems. The main goal of the course is to quickly review and then advance the student's existing knowledge of power systems analysis. Emphasis is on foundation theories, advanced analysis methods, developing conceptual insights, and gaining experience with applicable software simulation and analysis packages. Although today's software is quite advanced, in order to properly apply the software and interpret the results we must have both a good analytical understanding and a practical/conceptual "big picture" understanding of how the system behaves and of all of the interactions between the equipment and components that make up the system. Power systems consist of hundreds or thousands of "buses" or nodes, and the network equations dealt with may have thousands of variables. New smart grid technologies, operational complexities imposed by deregulation of the power industry, lessons learned from major blackouts, NERC system security/reliability concerns, installation of distributed generation, application of FACTS and other state-of-the-art equipment has renewed the need for sound analysis, simulation, and design skills. This course provides the foundation for the remaining power area graduate courses. Computer simulation methods, formerly combined with this course, are now taught in EE5240 .
Topics typically covered in this 14-week course and the software used are as follows (textbook, instructor, and priorities may alter coverage):
