simulation_objects.csv
This file is used to enter data about the data set as a whole. Each row specifies a global parameter with two values, one that applies to forecasts and another that applies to real-time data (actuals). The file has three columns:
Column Name |
Description |
---|---|
Simulation_Parameters |
Which global parameter is set by this row |
DAY_AHEAD |
The row’s value for forecast data and/or RUC plans |
REAL_TIME |
The row’s value as it applies to real-time data and/or SCED operations |
The following values of Simulation_Parameter are supported:
Simulation_Parameter |
Required? |
Parameter Description |
DAY_AHEAD |
REAL_TIME |
---|---|---|---|---|
Period_Resolution |
Yes |
The number of seconds between values in timeseries data files |
The number of seconds between values in DAY_AHEAD timeseries data files |
The number of seconds between values in REAL_TIME timeseries data files |
Date_From |
Yes |
The date and time of the first value in each timeseries data file. Most reasonable formats are accepted. |
The date and time of the first value in each DAY_AHEAD timeseries data file |
The date and time of the first value in each REAL_TIME timeseries data file |
Date_To |
Yes |
The latest date and time for which we have enough data in timeseries files to formulate a RUC or SCED. Most reasonable formats are accepted. See Date_To Details below. |
The latest date and time for which we have enough data in DAY_AHEAD timeseries data files to formulate a RUC |
The latest date and time for which we have enough data in REAL_TIME timeseries data files to formulate a SCED |
Look_Ahead_Periods_Per_Step |
Yes |
The default number of look-ahead periods to use in RUC or SCED formulations |
The default number of look-ahead periods to use in RUC formulations |
The default number of look-ahead periods to use in SCED formulations |
Look_Ahead_Resolution |
Yes |
The default number of seconds between each look-ahead period used in RUC or SCED formulations. See Look_Ahead_Resolution Details below. |
The default number of seconds between each look-ahead period in RUC formulations |
The default number of seconds between each look-ahead period in SCED formulations formulations |
Reserve_Products |
No |
Which reserve products to enforce for RUC plans or SCED operations. See Reserve_Products Details below. |
Which reserve products to enforce for RUC plans |
Which reserve products to enforce for SCED operations |
Date_To Details
The value of Date_To identifies the latest time for which there is enough data to formulate or RUC (for DAY_AHEAD) or SCED (for REAL_TIME), including look-ahead periods. This is not the date and time of the final value in timeseries data files. Instead, the Date_To is Look_Ahead_Periods_Per_Step * Look_Ahead_Resolution before the date and time of the final value in the timeseries data files.
For example, consider a data set with 24 look-ahead periods with a look-ahead resolution of 1 hour. If the final value in a timeseries is for April 10th at midnight, then Date_To is April 9th at midnight, because that is the latest time for which we have enough data to satisfy the 24 hour look-ahead requirement.
Look_Ahead_Resolution Details
The Look_Ahead_Resolution parameter is used to determine the date and time of the final value in timeseries data files, as described in Date_To Details. Despite its name, it is not used to specify the look-ahead resolution used during simulation. The actual look-ahead resolution used during simulation is determined by configuration parameters passed to Prescient. Prescient will interpolate the available data as necessary to honor the look-ahead resolution specified in its configuration parameters.
Reserve_Products Details
Some categories of reserve products may apply to RUC formulations, while others may apply to SCED formulations. This row allows you to configure which reserve product categories apply to each formulation type. Reserve product categories listed in the DAY_AHEAD column impose their requirements on RUC formulations, and reserve product categories listed in the REAL_TIME column impose their requirements on SCED formulations.
Specify applicable reserve product categories as a comma-separated list. Only listed reserve product categories will be imposed on corresponding formulations. Supported reserve products are Spin_Up, Reg_Up, Reg_Down, Flex_Up, and Flex_Down.
This row is optional. If you leave the row out, all reserve categories apply to both RUCs and SCEDs.
