Course Description:

This is an introductory course in the field of electrical power systems covering the areas of generation, transmission/sub-transmission, distribution and load. Power systems are complex interaction of these areas and students of this course would study the basics of each area to learn how these are interconnected and controlled for a well managed system. Electrical energy is one of the most convenient forms of energy and is used in many different applications requiring a wide range of power. Most of us depend on central generation and distribution of electrical power which may span geopolitical boundaries but the same concepts can be applied to distributed generation and usage.

This course will cover the fundamental concepts in planning and operation of modern electric power generation, transmission and distribution systems. Topics to be covered include: Power system structure and operation, modeling of components such transmission lines, transformers, generating plants and loads, power flow analysis, dynamics and control of multi-machine systems, system protection, mobile and isolated power systems, steady-state and transient stability, Smart-Grids, Micro-Grids and integration of renewable energy sources into the grid.

This knowledge should help the students in careers and/or research in electrical power generation, transmission and distribution, renewable energy sources, power electronic systems, electric and hybrid vehicles and use of electric motors and generators in an electrical power system.
