# Data and Models
### 1. Supported data formats
Currently PowerSAS.m supports extended PSAT (Matlab) data format. Support for other formats and data format conversion features will be added in future versions.

### 2. Extension of PSAT (Matlab) format
#### 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 N$times$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
