File formats
SpiceEV uses human-readable files for inputs, scenario definitions, configuration files and outputs. Not every type of input is part of the repository, as some data is classified and/or should be created by the user according to need.
File type: CSV
Needs one column with the drawn energy in kWh (can have more columns, but only one is relevant). The file is read line-by-line, with events starting at start_time and updating every interval (configurable).
File type: CSV
Needs one column with the energy produced in kWh (can have more columns, but only one is relevant). The file is read line-by-line, with events starting at start_time and updating every interval (configurable).
File type: CSV
Needs one column with the energy price in ct/kWh (can have more columns, but only one is relevant). The file is read line-by-line, with events starting at start_time and updating every interval (configurable). Can be created with generate_energy_price.py.
File type: text
Refer to generate.cfg and generate_from_simbev.cfg in examples folder.
File type: JSON
To be used in simulate.py. Defines general info (start_time, interval, n_intervals), constants (vehicle types, vehicles, grid connectors, charging stations, batteries) and events (external loads, feed-in, grid operator signals and vehicle events).
File type: text
Refer to price.cfg in examples folder.
File type: CSV
To be used in generate-scripts. Columns date, time and price [ct/kWh].
File type: JSON
Is created by generate.py or generate_from_simbev.py.
File type: text
Refer to simulate.cfg in examples folder.
File type: CSV
All power values are in kWh.
