General Data Formats
PowerModels.parse_file — Function.parse_file(file; import_all)Parses a Matpower .m file or PTI (PSS(R)E-v33) .raw file into a PowerModels data structure. All fields from PTI files will be imported if import_all is true (Default: false).
PowerModels.parse_json — Function.Matpower Data Files
The following method is the main exported methods for parsing Matpower data files:
PowerModels.parse_matpower — Function.We also provide the following (internal) helper methods:
parse_matpower_file
parse_matpower_string
matpower_to_powermodels
row_to_typed_dict
row_to_dict
mp_cost_data
split_loads_shunts
standardize_cost_terms
merge_generator_cost_data
merge_bus_name_data

add_dcline_costsPTI Data Files (PSS/E)
Note: This feature supports the parsing and conversion of PTI files into a PowerModels format for the following power network components: buses, loads, shunts (fixed and approximation of switched), branches, two-winding and three-winding transformers (incl. magnetizing admittance), generators, two-terminal dc lines, and voltage source converter HVDC lines.
The following method is the main exported method for parsing PSS(R)E v33 specified PTI data files:
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. Imports all remaining data from the PTI file if import_all is true (Default: false).
Parses directly from file
The following internal helper methods are also provided:
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.
PowerModels.parse_pti_data — Function.parse_pti_data(data_string, sections)Parse a PTI raw file into a Dict, given the data_string of the file and a list of the sections in the PTI file (typically given by default by get_pti_sections().
PowerModels.get_line_elements — Function.get_line_elements(line)Uses regular expressions to extract all separate data elements from a line of a PTI file and populate them into an Array{String}. Comments, typically indicated at the end of a line with a '/' character, are also extracted separately, and Array{Array{String}, String} is returned.
PowerModels.add_section_data! — Function.add_section_data!(pti_data, section_data, section)Adds section_data::Dict, which contains all parsed elements of a PTI file section given by section, into the parent pti_data::Dict
PowerModels.parse_line_element! — Function.parse_line_element!(data, elements, section)Parses a single "line" of data elements from a PTI file, as given by elements which is an array of the line, typically split at ,. Elements are parsed into data types given by section and saved into data::Dict
PowerModels.get_pti_dtypes — Function.get_pti_dtypes(field_name)Returns OrderedDict of data types for PTI file section given by field_name, as enumerated by PSS/E Program Operation Manual
PowerModels.get_pti_sections — Function.get_pti_sections()Returns Array of the names of the sections, in the order that they appear in a PTI file, v33+
PowerModels.psse2pm_dcline! — Function.psse2pm_dcline!(pm_data, pti_data)Parses PSS(R)E-style Two-Terminal and VSC DC Lines data into a PowerModels compatible Dict structure by first converting them to a simple DC Line Model. For Two-Terminal DC lines, "source_id" is given by ["IPR", "IPI", "NAME"] in the PSS(R)E Two-Terminal DC specification. For Voltage Source Converters, "source_id" is given by ["IBUS1", "IBUS2", "NAME"], where "IBUS1" is "IBUS" of the first converter bus, and "IBUS2" is the "IBUS" of the second converter bus, in the PSS(R)E Voltage Source Converter specification.
PowerModels.psse2pm_transformer! — Function.psse2pm_transformer!(pm_data, pti_data)Parses PSS(R)E-style Transformer data into a PowerModels-style Dict. "source_id" is given by ["I", "J", "K", "CKT", "winding"], where "winding" is 0 if transformer is two-winding, and 1, 2, or 3 for three-winding, and the remaining keys are defined in the PSS(R)E Transformer specification.
PowerModels.psse2pm_shunt! — Function.psse2pm_shunt!(pm_data, pti_data)Parses PSS(R)E-style Fixed and Switched Shunt data into a PowerModels-style Dict. "source_id" is given by ["I", "ID"] for Fixed Shunts, and ["I", "SWREM"] for Switched Shunts, as given by the PSS(R)E Fixed and Switched Shunts specifications.
PowerModels.psse2pm_load! — Function.psse2pm_load!(pm_data, pti_data)Parses PSS(R)E-style Load data into a PowerModels-style Dict. "source_id" is given by ["I", "ID"] in the PSS(R)E Load specification.
PowerModels.psse2pm_bus! — Function.psse2pm_bus!(pm_data, pti_data)Parses PSS(R)E-style Bus data into a PowerModels-style Dict. "source_id" is given by ["I", "NAME"] in PSS(R)E Bus specification.
PowerModels.psse2pm_generator! — Function.psse2pm_generator!(pm_data, pti_data)Parses PSS(R)E-style Generator data in a PowerModels-style Dict. "source_id" is given by ["I", "ID"] in PSS(R)E Generator specification.
PowerModels.psse2pm_branch! — Function.psse2pm_branch!(pm_data, pti_data)Parses PSS(R)E-style Branch data into a PowerModels-style Dict. "source_id" is given by ["I", "J", "CKT"] in PSS(R)E Branch specification.
