AGC's

1. Automatic Generation And
Control

2. AGC functionality
There are two main functions of AGC:
1. Load-frequency control (LFC). LFC must do two things:
a. Maintain system frequency
b. Maintain scheduled exports
2. Provide signals to generators for two reasons:
a. Economic dispatch
b. Security control
As its name implies, LFC is a control function. There are 3 main levels of control:
1. Primary control
2. Secondary control
3. Supplementary control

6. Speed Governor
Speed governor model
Speed governor model can be developed by considering various steady
state conditions. The resulting speed governor model is

7. Turbine
Turbine model
The turbine model requires a relation between changes in power output
of the steam turbine to changes in its steam valve opening XE .
