Timeseries Inputs
This section describes the timeseries input file.
Datetime
| Column Header
|
Description
|
| Datetime (he)
|
This column provides time stamps for the rest of the data. This should be formatted as a yyyy-mm-dd hh:mm:ss string. (e.g. "2021-01-25 15:00:00" would be January 25, 2021 at 3pm
Note: sometimes Excel or other editors will change the format of timestamps according to your settings. Please ensure these are formatted as described above to avoid errors.
These are timestep-ending timestamps, meaning that the time 02:00:00 represents the time step that ends at 2am. If the time step is 1 hour, then this would represent the interval starting a 1am and ending at 2am.
The amount these timestamps increment from row to row should match the time step input parameter. If the time step is 0.25 (15 minutes), then the first few time stamps might look like ("2022-01-01 00:15:00", "2022-01-01 00:30:00", "2022-01-01 00:45:00", "2022-01-01 01:00:00").
The number of time stamps should be equal to the number of hours in a year (8760 for non-leap years and 8784 for leap years) divided by dt for each optimization year. Subsequent opt_years should be appended to the bottom of the file.
