Load Powerflow Data Window

Access

The Data > Load Data Option in the Powerflow Case Definition Window Menu Bar.

Purpose

To:

  • Control the loading of all Definition input data in a single operation
  • Record the details of the last load operation for a specific Definition

Purpose

To load seven day Demand and Generation profile data into a Powerflow Case from an online database.

Components

Component Purpose

Keep and Overwrite Check box
Keeps existing profile data and overwrites with new data averaged with existing data, allowing averaged Demand profiles to be created using Demand data from discontinuous time periods (toggles with the Clear and Load Check box)
Last Load Operation Details
Records when Demand and Generation profile data was last loaded and if the load operation was succesful
Load Demand Data and Generation Check box
To include or exclude profile data from the next Load Operation
Reset Button
Restores the Profile Load Panel to its default settings

Load Transmission Data Panel

Access

The Data > Load Data menu option in the Powerflow Case Definition Window.

Purpose

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

The default EMarketOffer data source for Transmission System data

When uploading Transmission System data into a Powerflow Case EMarketOffer first checks the Inputs sub-folders for valid EM6/COMIT/Ellsoft files, and uses these in preference to data from an online database, even when a connection to obtain Transmission System data has been defined.

Transmission System Data Loading Modes

Transmission System data can be loaded into a Powerflow Case Definition in one of two modes:

  • Date Range Mode
  • Period Mode

Date Range Mode

Accessed by clicking on the "Date Range" tab under the "Transmission" heading.

Purpose

To select a date range for loading a Powerflow Case Definition with Transmission System data. This Mode is only available when Transmission System data can be obtained from EM6/COMIT/Ellsoft provided files.

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
Allows you to specify the inclusive dates to start/end loading Transmission data into the 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 and overwrites with new data from the database
Last Load Operation Details
Records when Transmission data was last loaded into the Definition
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 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

Accessed by clicking on the "Period" tab under the "Transmission" heading.

Purpose

To select a specific period which will provide the basic Transmission System data for all periods in your Powerflow Case Effective Date Range. This is the only loading option available when EM6/COMIT data files are not available.

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 Powerflow Case Effective Date Range. It does not keep specific record of Circuit re-ratings or Group Constraints, which are kept when loading in Date Range Mode.

Control of the Transmission data takes place through the Load Transmission Data Panel in Period Mode.
