When creating the Transmission System data ''EMarketOffer'' first uses the latest EM6/COMIT/Ellsoft supplied data file to build the basic system. The Transmission System is modelled as a set of Circuits with specific ratings (taking into account Summer and Winter changes).  Any line re-ratings scheduled in the Constraint data falling within the Forecast Effective Date Range are applied over the top of the original ratings.  Finally any Group Constraints that were or will be applied during the Forecast Effective Date Range are activated.

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'' uses EM6/COMIT/Ellsoft Constraint information to extract historical and expected Group Constraint data. Of the three types of Group Constraints (Permanent, Outage and Temporary), only the timing of future Permanent Constraints can be predicted using EM6 Constraint information.  You will need to monitor your sources of Transmission System data for updates to ensure your Forecast Definitions contain the latest Outage and Temporary Group Constraint data.
+
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
 +

=== 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.

 +
 
 +
=== Purpose ===
 +
To display a Forecast Definition's weekly Energy Offers profile for a specific Generation Unit.
 +
 
 +
=== Functionality ===
 +
The Graph appears as the Offers Graph embedded in the Edit Unit Information Window.  The functionality of the graph in this location is identical to that of the generic '''''[[EMO:Charts#The_Offers_Graph|Offers Graph]]''''' with the following exceptions:
 +
*The Display of Offers is restricted to the seven-day Offers profile for the Unit
 +
*An additional Day of Week picker allows you to quickly inspect the offer stack for any single day of the profile

== The Supply Curve Chart ==
 +
 
 +
=== Access ===
 +
The '''Graphs > Supply Curve''' option in the Forecast Definition Window.
 +
 
 +
=== Purpose ===
 +
The Supply Curve Graph displays the Offer Stack for the Current Data Set (excluding the Powerflow Case Data Source). The Graph appears in its own window and is updated whenever the Current Data Set changes.
 +
 
 +
The functionality of the graph in this location is identical to that of the generic '''''[[EMO:Charts#The_Supply_Curve_Graph|Supply Curve]]'''''.
 +
 
 +
== The Profiles Menu Option ==
 +
 
 +
=== Access ===
 +
Either the '''Profiles > Demand''' or '''Profiles > Offers''' options of the '''''Forecast Definition Window''''' Menu

 +
=== Purpose ===
 +
To:
 +
#Import and export Demand or Offers Profile files
 +
#Manually edit Demand for Offers figures for individual or groups of Trading Periods and Nodes
 +
 
 +
NOTE:  The formats of Demand and Offers Profile files are covered in '''''[[EMO:Data File Formats|Data File Formats]]'''''.
 +
 
 +
=== Items ===
 +
The Window displays the seven-day Offers or Demand Profile in a Data Grid with a column for each Node and a row for each Trading Period.  Data in a cell can be edited manually. Cutting and pasting to and from single or multiple cells is supported.

=== Importing into the Profile ===
 +
Demand or Offers data can be imported into the Forecast Definition Profile from any properly formatted file.  Selecting the '''File > Import''' menu option from the Profile Window opens the standard Windows file browsing window to locate the import file.
 +
 
 +
An imported Profile may contain data for:
 +
*One or many Nodes
 +
*One or many profile days
 +
*One or many Trading Periods
 +
 
 +
 
 +
'''WARNING!''' Demand for Nodes and Offer for Units not currently contained in the Profile's Transmission System data will be loaded, but will not play any role in the dispatch analysis unless the new Node is manually connected with one or more user-defined Circuits.

NOTE: If you choose to Keep and Overwrite the data loaded from file it is possible to mix Offers data sourced from file and database.


>> To Load a Forecast Definition with Offers from Files:

  1. First enter the Effective Date Range of the forecast
  2. Select the dates of the Offers data you wish to use taking care to note the days of the week for these dates (for initial loading it is best to select seven consecutive and complete Offers files with the earliest file having the same day of the week as the first day of your selected Effective Date Range)
  3. Bring up the Load Offers from Files Panel and use the "Get Files ..." button which opens the Windows file browser to locate the required Offers files
  4. Highlight the files to be loaded (NOTE: holding the <SHIFT> key while right clicking with the mouse allows multiple files to be highlighted)
  5. Click open to select the files and display them in the Selected Offers Files box
  6. Check the Load Offer Data Check box
  7. The Offers data will be loaded with the next load data operation.


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:
