AIM
To become familiar with the modeling of various power system components and different
methods of analysis for power system planning and operation.
OBJECTIVES
 To model steady-state operation of large-scale power systems and to solve the
power flow problems using efficient numerical methods suitable for computer
simulation.
 To model and analyse power systems under abnormal (fault) conditions.
 To model and analyse the dynamics of power system for small-signal and large
signal disturbances and o design the systems for enhancing stability.
