2.1 Automatic generation control (AGC) model
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Here PowerSAS provides a simple AGC model. It is named as ``Agc.con`` in
data files and it is a :math:`\text{N}\times \text{4}` matrix. Each
column is defined as below: Column \| Content ——-\| ————- 1 \| Bus index
2 \| Reciprocal of turbine governor gain on bus 3 \| Effective damping
ratio on bus 4 \| Reciprocal of AGC control time constant
