== The Data Source Manager ==
 +
The '''''Data Source Manager''''' is located at the bottom of the Control Panel.
 +
 
 +
=== Definition ===
 +
A '''''Data Source''''' determines the context for viewing Maps, Reports, Charts and Information Windows.  There are four Data Source types:
 +
#Data from the '''''Market'''''
 +
#Data from a '''''Forecast'''''
 +
#Data from a '''''Powerflow Case'''''
 +
#Data from a created '''''Scenarios'''''
 +
 
 +
Access to Data Sources is handled through the Main Window Data Source Manager.

=== Managing the Market Data Source ===
 +
 
 +
==== Purpose ====
 +
To provide historical Market data for viewing in the '''''[[EMO:The Presentation Interface|Presentation Interface]]''''' and '''''[[EMO:The_Edit_Menu#The_Reports_and_Graphs_Option|Reports]]'''''.
 +
 
 +
==== Usage ====
 +
<span style="color:#2E5894">
 +
'''>> To place the Presentation Interface into Market Data Source mode and view Market Data:'''
 +
#highlight "Market" in the Main Window Data Source Manager
 +
#Click the View button or double-click on the highlighted "Market" text
 +
 
 +
Notes:
 +
#Simply placing the Presentation Interface into Market Data Source Mode will not replace the Current Data Set with Market data
 +
#''EMarketOffer'' launches with a Market Data Source using the actual calendar date and time.
 +
#When switching to Market Data Source mode ''EMarketOffer'' takes the 'Current Date' from the previously loaded Data Source.  For example if you were looking at a Forecast with an Effective Date Range some time in the future, switching to Market Data Source Mode and loading data will cause displays to go blank as EMarketOffer fails to find any historical data. Alternatively if you are in Scenario Data Source Mode and looking at a Scenario based on a historical period, switching to Market Data Source Mode will cause actual (historical) data for the date and period of the Scenario to be loaded.
 +
 
 +
=== Managing the Forecast Data Source ===
 +
 
 +
==== Purpose ====
 +
To provide data from Forecast Runs for viewing in the '''''[[EMO:The Presentation Interface|Presentation Interface]]''''' and '''''[[EMO:The_Edit_Menu#The_Reports_and_Graphs_Option|Reports]]'''''.
 +
 
 +
==== Usage ====
 +

 +
'''>> To place the Presentation Interface into Forecast Data Source mode:'''
 +
#highlight "Forecast" in the '''''[[EMO:Control_Panel_Components#The_Data_Source_Manager|Main Window Data Source Manager]]'''''
 +
 
 +
Unlike the Market Data Source which has only one discrete set of data for any given Trading Period, the Forecast Data Source provides access to the many discontinuous, discrete and potentially overlapping data sets produced by Forecast Runs.
 +
 
 +
<span style="color:#2E5894">
 +
'''>> To access the output of individual Forecast Runs:'''
 +
#Place the Presentation Interface into Forecast Data Source Mode

NOTES:
 +
#Simply placing the Presentation Interface into Scenario Data Source mode will not replace the currently loaded data with Scenario data
 +
#Because Scenarios apply to only one period on one date, the Current Date and Periods is set to match those of the Scenarios.
 +
#Scenarios can be created from the following Data Sources:
 +
##The Market Data Source providing historical offers exist for the Scenario period
 +
##Any Forecast output
 +
##Any Scenario that has been amended during an analysis session
 +
 
 +
 
 +
== The Circuit Colouring Panel ==
 +
The Cicuit Colouring Panel can, when applicable, be found beneath the View Manager in the Main Window Control Panel.
 +
 
 +
=== Purpose ===
 +
To modify the use of coloured Circuits on any Main, Secondary or Inset map to help rapidly identify situations of interest in the Transmission System.
 +
 
 +
=== Loading View Mode ===
 +
In Loading View mode circuits are colour-graded according to their loading.  Lines with low loading percentages are coloured according to the colour selected in the '''''Map Settings''''' function.  Typically the closer a Circuit's loading approaches its capacity the 'hotter' its colouring becomes (100% loaded circuits are typically coloured bright red).
 +
 
 +
NOTE: For the Market Data Source loading cannot be calculated with 100% certainty and therefore the circuit colouring is based on probable rather than actual loadings.
 +
 
 +
=== Constraint View Mode ===
 +
In Constraint View Mode Circuits are coloured as selected in the '''''Map Settings''''' function, except for those that are constraining (100% of Capacity). These circuits are coloured bright red (also changeable through the Map Settings function).
 +
 
 +
If a constraint occurs within a substation then the substation is highlighted with a large "glowing" circle.  The constrained line(s) will appear highlighted in the inset map for the substation.
 +
 
 +
NOTE: Identification of Constraints only occurs with the Forecast and Scenario Data Source in periods with a feasible dispatch.  Constraints don't have their usual meaning in Market View or Powerflows.  However, in Market View you can use the Price Diff colouring feature to help determine if and where a constraint has caused price separations.
 +
 
 +
=== Price Difference View Mode ===
 +
In Price Difference View mode Circuits are colour graded according nodal price difference between From and To Nodes.  The greater the price difference in the direction of flow (most likely due to a binding constraint) the warmer the colour will be relative to the standard circuit colour (large differences being displayed in bright red).  In cases where a price difference is in the opposite direction to flow (most likely to occur with the spring washer effect) the cooler the circuit colour will be relative to the standard circuit colour (largest difference displayed in deep blue).
 +
 
 +
 
 +
== The Messages Panel ==
 +
The Messages Panel shows messages such as when an infeasibility occurs in a dispatch solve.  For further discussion on interpretation of the messages in the Infeasibilities Panel see the section on '''''[[EMO:Infeasibilities|Infeasibilities]]'''''.

Figure 1 - Example of a Control Panel for the Market Data Source

Purpose

To provide important Current Data Set information and access to functionality not accessible through the Menu Bar.

The appearance of the Control Panel changes with the context of the Main Window so not all of the following features will be visible in each different Control Panel view.

The Data Source Panel

This is the panel at the top of the Control Panel.

Purpose

To provide information about the Current Data Source and allow you select periods to view using the Date and Time Selector (where appropriate).

Market Data Source

When Market is selected as the Current Data Source, the text "Data Source: Market" is shown in the top left hand corner. Below this is an area for selection of Date, time and time period within the Market Data Source.

Forecast Data Source

When Forecast is selected as the Current Data Source, the text "Data Source: Forecast" is shown in the top left hand corner.

Components

Component Purpose
Forecast Parameters
Used to indicate the Forecast name and the Effective Date Range
Function Buttons
Used to:
  • Edit the underlying Forecast Definition
  • Cause the first Trading Period in the Effective Date Range to be displayed in the Presentation Interface
  • Enter Forecast Summary Mode
Date and Time Selector
Selection of Current Data Set within the Forecast Data Source
Summary Mode

In Forecast Summary mode the Current Data Source Panel contains only the Data Source Divider - indicating the Current Data Set is drawn from a Forecast.

Scenario Data Source

When Scenario is selected as the Current Data Source, the text "Data Source: Scenario" is shown in the top left hand corner. Below this the Scenario name and version number is listed in a Grid. Located under the grid are buttons which can be used to:

  • Enter Marginal Analysis Mode. In Scenario Marginal Analysis mode the Current Data Source Panel contains only the top line of text (i.e. "Data Source: Scenario") - indicating the Current Data Set is drawn from a Scenario.
  • Redispatch the Scenario (after changing one or more Dispatch Factors)
  • Save the amended Scenario as new Version

Date and Time Selector

Purpose

To select the date and period of the Current Data Set for Market, Powerflow Case and Forecast Data Sources. This period is referred to as the 'Current Period'.

>> To Set the Current Date:

  1. Open the Calendar by clicking on the down-pointing arrow head in the Date Selector.
  2. Use the Calendar navigation features to select the day to become 'Current'
Calendar Features
  • The current Month and Year is displayed in the blue header
  • The current Month can be changed using the 'Previous' and 'Next' arrow keys in the blue header
  • The current Day is highlighted with a blue ellipse
  • A new current Day can be selected by clicking on the required date with the mouse
  • The current day can be changed using the arrow keys on your keyboard. Using <page up/down> skips forward/back a whole month and <Ctrl><Page Up/Down> skips forward/back a whole year
  • Clicking on the actual date (today's date) displayed at the foot of the calendar, causes the current day marker to move to this date.
  • Clicking on the year displayed in the blue header area reveals an up and down arrow - clicking and holding on these arrows causes the current year to scroll backwards or forwards in time until the mouse button is released.
  • Clicking on the month name in the blue header area reveals a drop-down list of months which can be used to select the current month

NOTE: It is also possible to alter the current date without invoking the Calendar, by highlighting the Day, Month and Year fields in the Date Selector and either typing the text you want or using the up/down arrow keys

Period Selection

The Current Period may be selected by:

  • Clicking the required Trading Period number in the horizontal Period Selection Bar (the blue highlight indicates the currently selected Trading Period)
  • Using the arrow keys in the Period Selection Roller
  • Typing into the Trading Period text box in the Roller

The View Manager

The View Manager is located directly beneath the Messages Panel.

Purpose

A View is a pre-defined area of the Main Map which can be recalled to fit into the Main or a secondary Map Window. The View Manager allows you to create certain views of the Map and quickly return to these views simply by clicking on the required view in the drop-down list. Views can only be created through the Main Window View manager which is visible in the Main Window for all Data Sources (Market, Forecast, Powerflow Case and Scenario).

>> To create a new View:

  1. Use the Map Navigation Features to position a section of the Main Map that you want to be able to recall in the Main Window Map Panel
  2. Click on a View name in the View Manager and press the <INSERT> Key to open the Add View dialogue
  3. Enter the name you wish to call the view and click 'OK' (The view name will now appear in the Views List in the View Manager)

>> To recall a previously created View in the Main Window Map Panel:

  1. Expand the drop-down list of views and click on the view you want to see

>> To recall a previously created View in a Secondary Map Window:

  1. Expand the Secondary Map View Selector (double arrow head in the top left corner)
  2. Select the required View from the second drop down box
  3. The selected View will now be displayed in the Secondary Map Window

>> To Delete a View:

  1. Highlight the View to be deleted in the Views list and press the <DELETE> Key
  2. Confirm the delete in the pop dialogue box
  3. The View will be removed from all View lists

Trading Period Summary

Purpose

To display key indicator totals for the Current Data Source. You can select the NZ tab to get grid-wide totals and averages, or the Reserve Regions tab to get totals and averages by island.

Entities

Data Entity Unit Description (for the Current Period)
Ave. Price
$/MWh
Average of all Nodal Prices (the average is not load weighted) - always zero for Powerflow Case Data Sources
Load
MW
Total system demand
Generation
MW
Total system injection
Losses
MW
Difference between total injection and off-take
Imbalance

The difference between load and generation (visible only for the Market Data Source to assist in identifying inconsistencies in input data). This does not appear when the Data Source is a Scenario or Forecast because the Imbalance is always zero in this case.

NOTE: When in Summary Mode the Current Trading Period Summary displays average values for the whole Forecast or Powerflow Case.

The Data Source Manager

The Data Source Manager is located at the bottom of the Control Panel.

Definition

A Data Source determines the context for viewing Maps, Reports, Charts and Information Windows. There are four Data Source types:

  1. Data from the Market
  2. Data from a Forecast
  3. Data from a Powerflow Case
  4. Data from a created Scenarios

Access to Data Sources is handled through the Main Window Data Source Manager.

Managing the Market Data Source

Purpose

To provide historical Market data for viewing in the Presentation Interface and Reports.

Usage

>> To place the Presentation Interface into Market Data Source mode and view Market Data:

  1. highlight "Market" in the Main Window Data Source Manager
  2. Click the View button or double-click on the highlighted "Market" text

Notes:

  1. Simply placing the Presentation Interface into Market Data Source Mode will not replace the Current Data Set with Market data
  2. EMarketOffer launches with a Market Data Source using the actual calendar date and time.
  3. When switching to Market Data Source mode EMarketOffer takes the 'Current Date' from the previously loaded Data Source. For example if you were looking at a Forecast with an Effective Date Range some time in the future, switching to Market Data Source Mode and loading data will cause displays to go blank as EMarketOffer fails to find any historical data. Alternatively if you are in Scenario Data Source Mode and looking at a Scenario based on a historical period, switching to Market Data Source Mode will cause actual (historical) data for the date and period of the Scenario to be loaded.

Managing the Forecast Data Source

Purpose

To provide data from Forecast Runs for viewing in the Presentation Interface and Reports.

Usage

>> To place the Presentation Interface into Forecast Data Source mode:

  1. highlight "Forecast" in the Main Window Data Source Manager

Unlike the Market Data Source which has only one discrete set of data for any given Trading Period, the Forecast Data Source provides access to the many discontinuous, discrete and potentially overlapping data sets produced by Forecast Runs.

>> To access the output of individual Forecast Runs:

  1. Place the Presentation Interface into Forecast Data Source Mode
  2. Click the expander box next to the Forecast Data Source header (marked '+' )
  3. Highlight the desired Forecast output from the expanded list
  4. Click the View button or Double-click the Forecast Definition name in the Data Source Manager

Features

Feature Purpose
Data Source Indicator
Shows the currently operative mode (Forecast) in the top left corner of the control panel
View Button
Causes the Forecast data to be loaded into the Presentation Interface
Create Button
Allows you to create a new Forecast Definition by opening a blank Forecast Definition Window

When the Forecast Data Source browser is expanded and a single Forecast highlighted the following additional features are displayed in the control panel:

Feature Purpose
Data Source Indicator

Delete Button
Allows you to delete the highlighted Forecast (this deletes the Forecast Definition and all associated output). You are required to confirm the delete through a dialogue box.
Edit Button
Allows you to edit the highlighted Forecast Definition through the Forecast Definition Window

NOTE: Simply placing the Presentation Interface into Forecast Data Source mode will not replace the currently loaded data with Forecast data.


Managing the Powerflow Data Source

Purpose

To provide data from Powerflow Case Analyses for viewing in the Presentation Interface and Reports.

Usage

>> To place the Presentation Interface into Powerflow Case Data Source Mode:

  1. highlight "Powerflow" in the Main Window Data Source Manager

The Powerflow Case Data Source provides access to the many discontinuous, discrete and potentially overlapping data sets produced by Powerflow Case analysis.

>> To access the output of an individual Powerflow Case Analysis:

  1. Place the Presentation Interface into Powerflow Case Data Source Mode
  2. Click the expander box next to the Powerflow Case Data Source header (this is marked with a '+' sign)
  3. Highlight the desired Powerflow Case output from the expanded list
  4. Click the view button or double-click the highlighted Powerflow Case name

Features

Feature Purpose
Data Source Indicator
Shows the currently operative mode (Powerflow) in the top left corner of the control panel.
View Button
Causes Powerflow data to be loaded into the Presentation Interface
Create Button
Allows you to create a new Powerflow Case Definition by opening a blank Powerflow Case Definition Window

When the Powerflow Case Data Source browser is expanded and a single Powerflow Case highlighted the following additional features are displayed in the control panel

Feature Purpose
Data Source Indicator
Now shows both the Data Source mode and the name of the currently selected Powerflow Case
Delete Button
Allows you to delete the highlighted Powerflow Case (this deletes the Powerflow Case Definition and all associated output). You are required to confirm the delete through a dialogue box.
Edit Button
Allows you to edit the highlighted Powerflow Case Definition through the Powerflow Case Definition Window

NOTE: Simply placing the Presentation Interface into Powerflow Case Data Source mode will not replace the currently loaded data with Powerflow Case data.

Managing the Scenario Data Source

Purpose

To provide data from previously saved Scenarios for viewing in the Presentation Interface and Reports.

Definition

A Scenario is a snapshot for a single Trading Period created from either a Forecast or Market Data Source.

Usage

>> To place the Presentation Interface into Scenario Data Source mode highlight "Scenario" in the Main Window Data Source Manager

The Scenario Data Source provides access to the many discrete, single-period Scenarios.

>> To access a Scenario:

  1. Place the Presentation Interface into Scenario Data Source Mode
  2. Click the expander box next to the Scenario Data Source header (this is marked with a '+' sign)
  3. Highlight the desired Scenario from the expanded list
  4. Click the View button or double-click the highlighted Scenario name

Features

Feature Purpose
Data Source Indicator
Shows the currently operative mode (Scenario) in the top left corner of the control panel
View Button
Causes Scenario data to be loaded into the Presentation Interface
Create Button
Allows you to create a new Scenario using the dispatch data for the currently displayed period

When the Scenario Data Source browser is expanded and a single Scenario highlighted the following additional features are displayed in the control panel

Feature Purpose
Data Source Indicator
Now shows both the Data Source mode and the name of the currently selected Scenario
Delete Button
Allows you to delete the highlighted Scenario. You are required to confirm the delete through a dialogue box.

NOTES:

  1. Simply placing the Presentation Interface into Scenario Data Source mode will not replace the currently loaded data with Scenario data
  2. Because Scenarios apply to only one period on one date, the Current Date and Periods is set to match those of the Scenarios.
  3. Scenarios can be created from the following Data Sources:
    1. The Market Data Source providing historical offers exist for the Scenario period
    2. Any Forecast output
    3. Any Scenario that has been amended during an analysis session


The Circuit Colouring Panel

The Cicuit Colouring Panel can, when applicable, be found beneath the View Manager in the Main Window Control Panel.

Purpose

To modify the use of coloured Circuits on any Main, Secondary or Inset map to help rapidly identify situations of interest in the Transmission System.

Loading View Mode

In Loading View mode circuits are colour-graded according to their loading. Lines with low loading percentages are coloured according to the colour selected in the Map Settings function. Typically the closer a Circuit's loading approaches its capacity the 'hotter' its colouring becomes (100% loaded circuits are typically coloured bright red).

NOTE: For the Market Data Source loading cannot be calculated with 100% certainty and therefore the circuit colouring is based on probable rather than actual loadings.

Constraint View Mode

In Constraint View Mode Circuits are coloured as selected in the Map Settings function, except for those that are constraining (100% of Capacity). These circuits are coloured bright red (also changeable through the Map Settings function).

If a constraint occurs within a substation then the substation is highlighted with a large "glowing" circle. The constrained line(s) will appear highlighted in the inset map for the substation.

NOTE: Identification of Constraints only occurs with the Forecast and Scenario Data Source in periods with a feasible dispatch. Constraints don't have their usual meaning in Market View or Powerflows. However, in Market View you can use the Price Diff colouring feature to help determine if and where a constraint has caused price separations.

Price Difference View Mode

In Price Difference View mode Circuits are colour graded according nodal price difference between From and To Nodes. The greater the price difference in the direction of flow (most likely due to a binding constraint) the warmer the colour will be relative to the standard circuit colour (large differences being displayed in bright red). In cases where a price difference is in the opposite direction to flow (most likely to occur with the spring washer effect) the cooler the circuit colour will be relative to the standard circuit colour (largest difference displayed in deep blue).


The Messages Panel

The Messages Panel shows messages such as when an infeasibility occurs in a dispatch solve. For further discussion on interpretation of the messages in the Infeasibilities Panel see the section on Infeasibilities.
