AIM

To become familiar with different aspects of modeling of components and system and different methods of analysis of power system planning and operation.

OBJECTIVES

i. To model steady-state operation of large-scale power systems and o solve the power flow problems using efficient numerical methods suitable for computer simulation.

ii. To model and analyse power systems under
abnormal (fault) conditions.

iii. To model and analyse the dynamics of power system for small-signal and large signal disturbances and o design the systems for enhancing stability.
