The Load Transmission Data Panel

Access

The Forecast Definition Window using the Data > Load Data menu option.

Purpose

To specify the date range of Transmission data you want to load into a Forecast Definition from your default Transmission System data source.

Transmission System Data Loading Modes

A Transmission System data can be loaded into a Forecast Definition in one of two modes:

• Date Range Mode, which uses system data for all periods in the Forecast's Effective Date Range (or a user-entered date range)
• Period Mode, which uses system data from a single period and applies it to all periods in the Forecast's Effective Date Range

How EMarketOffer internally constructs Transmission System data

When creating the Transmission System data EMarketOffer first uses the latest data files to build the basic grid. The Transmission System is modelled as a set of lines with specific ratings (taking into account Summer, Shoulder and Winter changes, or VLRs). Any line re-ratings scheduled in the falling within the Forecast Effective Date Range are applied over the top of the original ratings. Finally any Equation Constraints that were or will be applied during the Forecast Effective Date Range are activated accordingly.

NOTE: EMarketOffer currently only accesses historical grid data to build grids. When Forecasting, you will need to add your own future data where you think it will be different to what happened in the past. (As of early 2013, Energy Link is working on new capability that will allow EMarketOffer to predict equation constraints for future grid configurations.)

Date Range Mode

Access

By clicking on the Date Range tab in the Load Transmission Data Panel.

Purpose

To select a date range for loading Transmission System data into a Forecast Definition.

Load Items

A Definition loaded through the Date Range Mode will contain the following:

• Base Grid Configuration
• All re-ratings applied during the date range
• All Group Constraints applied during the date range

Components

Component	Purpose
Date Selectors	Allow you to select the days for which to start and finish loading Transmission Data into the Forecast Definition
Clear and Load Check box	Clears all existing Transmission data before loading new data (toggles with the Keep and Overwrite check box)
Keep and Overwrite Check box	Keeps existing Transmission data ad overwrites with new data
Last Load Operation Details	Records when Transmission data was last loaded
Include Transmission Data in Load Check box	To include or exclude Transmission data from the next Load Operation
Reset Button	Restores the entire Transmission Load Panel (file and database) to its default settings: Start Date = First date of the Forecast Definition Effective Date Range End Date - Last date of the Effective Date Range Clear and Load = Checked Include Transmission System data in next load operation

Period Mode

Purpose

To select a specific period to provide the basic Transmission System data for all periods in your Forecast Effective Date Range.

NOTE: When using Period Mode EMarketOffer applies the basic grid and re-ratings to obtain the System Configuration for the Period and applies this to all periods in the Effective Date Range. It does not keep specific record of Circuit re-ratings or Equation Constraints, which are kept when loading in Date Range Mode.

Components

Component	Purpose
Date Selector	Selects the inclusive date of the period to load Transmission data into the Forecast Definition
Period Selection Bar	To select the loading Period
Period Selection Box	Used with the mouse or by text entry to select the loading Period
Clear and Load Check box	Clears all existing Transmission data before loading new data (toggles with the Keep and Overwrite check box)
Keep and Overwrite Check box	Keeps existing Transmission data and overwrites with new data from the database
Last Load Operation Details	Displays when Transmission System data was last loaded
Include Transmission Data in Load Check box	Allows you to include or exclude Transmission data from the next Load Operation
Reset Button	Restores the entire Transmission Load Panel (file and database) to its default settings: Start Date = First date of the Powerflow Case Definition Effective Date Range End Date - Last date of the Effective Date Range Clear and Load = Checked Include Transmission System data in next load operation
