| Description: | Frequency of inventory balance |
Commodity Balance Period
determines the frequency with which inventory balance constraints are
enforced in chronological simulation. This setting can take the
following values:
- Interval (value=0) (default)
- Storage is balanced every interval, where the interval length is
set by Horizon Periods
per Day.
- Hour (value=6)
- Storage is balanced at the end of every hour e.g. if
intervals are 10-minutes the storage is balanced only at the end of
every full hour (6 intervals).
- Day (value=1)
- Storage is balanced at the end of every day.
- Week (value=2)
- Storage is balanced at the end of every week.
- Month (value=3)
- Storage is balanced at the end of every month.
- Year (value=4)
- Storage is balanced at the end of every year.
Reducing the frequency with which inventory is balanced can improve
simulation time. The trade off is that between balance periods the
inventory limits are not enforced. For example if you set Balance Period
= "Day"(1) the limits will be enforced only at the end of each day. This
approximation might be acceptable for long and mid-term modelling if the
speed up in simulation time is significant
e.g. in
LT
Plan run in chronological mode. Another application is in
sub-hourly modelling where balancing every interval is expensive
computationally and not always necessary.
