ANDES currently supports the following input formats:
- ANDES Excel (.xlsx)
- MATPOWER (.m)
- PSS/E RAW (.raw)
- PSS/E DYR (.dyr), work in progress
- Dome (.dm), work in progress
The ANDES xlsx format is a newly introduced format since v0.7.0. This format uses Microsoft Excel for conveniently viewing and editing model parameters.
Each worksheet in the xlsx file contains parameters for one model. The name of the worksheet is the model name. The first rows in each woeksheet are the parameter field names. Starting from the second row are the parameter for devices, each like representing one device.
Input data needs to have consistent types for idx
. Both string and
numerical types are allowed for idx
, but the original type and the
referencing type must be the same. For example, suppose we have a bus
and a connected PQ. The Bus device may use 1
or '1'
as its idx
, as
long as the PQ device uses the same value for its bus
parameter.
The ANDES xlsx reader will try to convert data into numerical types when
possible. This is especially relevant when the input idx
is string
literal of numbers, the exported file will have them converted to
numbers. The conversion does not affect the consistency of data.
The following parameter checks are applied after converting input values to array:
- Any
NaN
values will raise aValueError
- Any
inf
will be replaced with (10^{10}), and-inf
will be replaced with (-10^{10}).
