Objectives
The students should be able to:
Understand and describe the main aspects of generation, transmission, distribution, trade and use of electric energy, including the recent changes in the electric sector.
Calculate the electric parameters of lines, set the PI model and use it to analyze the different operating points.
Understand and explain the main aspects of the technical management of a power system and formulate and solve control problem at a basic level.
Formulate the power flow problem.
Use the p.u. system and the DC power flow model to solve network analysis problems.
