EEE 4-1 PSOC Important Topics
Preamble:
This subject deals with economic operation of Power Systems, Hydrothermal scheduling and modeling of
turbines, generators and automatic controllers. It emphasizes on single area and two area load frequency
control and reactive power control.
Course Objectives:
x To understand optimal dispatch of generation with and without losses.
x To understand the optimal scheduling of hydro thermal systems.
x To understand the optimal unit commitment problem.
x To understand the load frequency control for single area system with and without controllers
x To understand the load frequency control for two area system with and without controllers
x To understand the reactive power control and compensation of transmission lines.
