Data and Models

1. Supported data formats

Currently PowerSAS.m supports extended PSAT (Matlab) data format.

In addition, PSS/E data format can be easily converted to the PSAT data format using the psse2mpc function by MATPOWER and the matpower2psat function by PSAT. A sample code to convert a PSS/E *raw file to the PSAT format is below:

casename = 'ieee14'
[mpc, warnings] = psse2mpc(horzcat(casename,'.raw'),horzcat(casename,'.m'));
check = matpower2psat(horzcat(casename,'.m'), pwd);

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 \(\text{N}\times \text{4}\) 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
