Examples of Time Horizon in a sentence
The RTM applications run at periodic intervals, every 5 or 15 minutes, with a Time Horizon that ends at or beyond the Time Horizon of the previous run.
Similarly, the RTM applications that have Unit Commitment capabilities can commit resources optimally within their Time Horizon, however, because that Time Horizon is short (a few hours at most), only Fast-Start, Short-Start and Medium Start Units can be committed.
The main differences are the following:The IFM application uses hourly time intervals, whereas the RTM applications use sub-hourly time intervals within their Time Horizon.The Time Horizon of the IFM application spans the next Trading Day, whereas the Time Horizon of the RTM applications is variable (due to submission timelines limiting the availability of real-time bids beyond the end of the next hour) and spans the current and next few Trading Hours at most.
Almost all resources can be considered for optimal commitment, except for resources with extremely long Start-Up, because the full cost impact of commitment decisions for these resources cannot be evaluated within the IFM Time Horizon.
The Time Horizon for the STUC optimization run will extend three hours beyond the Trading Hour for which the RTUC optimization was run, and will replicate the Bids used in that Trading Hour for these additional hours.
At the top of each Trading Hour, immediately after the RTUC run is completed, the CAISO performs an approximately five (5) hour Short-Term Unit Commitment (STUC) run using SCUC and the CAISO Forecast of CAISO Demand to commit Medium Start Units and Short Start Units with Start-Up Times greater than the Time Horizon covered by the RTUC.
Results for time intervals other than the second (binding) one in the Time Horizon are advisory since they are recalculated the next time the application runs.The IFM application uses Demand Bids to clear against Supply Bids, whereas the RTM applications use CAISO Forecast of CAISO Demand and final scheduled exports.
Each applicable Transmission Owner and applicable Generator Owner, without any intentional time delay, shall notify the control center holding switching authority for the associated applicable line when the applicable Transmission Owner and applicable Generator Owner has confirmed the existence of a vegetation condition that is likely to cause a Fault at any moment [Violation Risk Factor: Medium] [Time Horizon: Real- time].M4.
The STUC will only decommit a resource to the extent that resource’s physical characteristics allow it to be cycled in the same Time Horizon for which it was decommitted.
Each applicable Transmission Owner and applicable Generator Owner shall perform a Vegetation Inspection of 100% of its applicable transmission lines (measured in units of choice - circuit, pole line, line miles or kilometers, etc.) at least once per calendar year and with no more than 18 calendar months between inspections on the same ROW14 [Violation Risk Factor: Medium] [Time Horizon: Operations Planning].M6.
