Hi - this is a weighting to convert a time slice in a representative day into the number of hours it represents in a year.
For example if you have a representative day with 12 intervals which represents 2 days per year, then each interval represents 4 hours, because:
- Each interval within the day is 2 hours (24 hours divided into 12)
- The representative day happens twice a year, so that interval happens twice a year.
So the weight for a time-slice is (24 / number of slices in day) * 365 * (day frequency / sum of day frequencies).
Hope this helps.
