Cairn timeseries files

A Cairn timeseries file gives all the input and output data used for the simulation and optimization process.

• Possible input data are :

  • the “SourceLoad” flux and environmental impacts,

  • the energy and materials buy and sell prices,

  • the profile for converter use,

  • the profile for charge/load and discharge/unload for storages.

• Possible output data are the “SourceLoad” flux used for modelling the imposed loads.

A Cairn timeseries file is a CSV file ; the separator is the semicolumn (“;”) and is formatted as the following (see Table. 6) :

• 4 compulsory header rows that give :

  1. the name of the timeseries, the first column give the time timeseries in second,

  2. a comment, the time comment is the starting point date,

  3. the unit, the time unit is the second,

  4. a boolean used in case of PEGASE coupling.

• Others rows giving for each time the values of all parameters.

Caution

• The time step of the Cairn simulation is given by Cairn component.

• The Cairn process will interpolate in the timeseries file to find the values at a given time.

• If the simulation time is higher than the maximum time of the timeseries file, the Cairn process will loop along the file.
