General Data Formats

PowerModels.parse_file — Function.
parse_file(file)

Parses a Matpower .m file or PTI (PSS(R)E-v33) .raw file into a PowerModels data structure.

PowerModels.parse_json — Function.

Matpower Data Files

The following two methods are the main exported methods for parsing matpower data files:

parse_matpower
parse_matpower_data

We also provide the following (internal) helper methods:

standardize_cost_order
update_branch_transformer_settings
merge_generator_cost_data
merge_bus_name_data
parse_cell
parse_matrix
parse_matlab_data
split_line
add_line_delimiter
extract_assignment
extract_mpc_assignment
type_value
type_array
build_typed_dict
extend_case_data
mp_data_to_pm_data
split_loads_shunts

PTI Data Files (PSS/E)

Note: This feature is currently in development, and only partial parsing of and conversion of PTI files into a PowerModels format is supported. The following power network components are currently supported: buses, loads, shunts (fixed and approximation of switched), branches, two-winding transformers (without magnetizing admittance), and generators. There is early support for two-terminal dc lines, but this feature should not be relied upon.

The following method is the main exported method for parsing PTI data files:

PowerModels.parse_pti — Function.
parse_pti(filename)

Open PTI raw file given by filename, passing the file contents as a string to the main PTI parser, returning a Dict of all the data parsed into the proper types.

source
PowerModels.parse_psse — Function.
parse_psse(pti_data)

Converts PSS(R)E-style data parsed from a PTI raw file, passed by pti_data into a format suitable for use internally in PowerModels.

source

Parses directly from file
