Data Initialisation
EMarketOffer requires two types of externally sourced input data:
- Transmission System data
- Market data
Transmission System Data
EMarketOffer creates a set of Transmission System data (circuit details, line re-ratings and group constraints) at run time from one of three sources:
- Historical transmission system data files provided by Energy Link
- Transmission system files sourced through the online EM6 or COMIT data services
- In-house Transmission System databases
On startup EMarketOffer uses Transmission System data from EM6/COMIT files in the Grid sub-folder by preference unless the Use Grid File Inputs box in the Source Data Administration Window is checked. External database connections are used as a secondary data source where these files are absent or invalidly formatted.
WARNING! EMarketOffer will ignore any database links defined through the Data Connection Window for Transmission System data if the data can be obtained from file and the Use Grid File Inputs box in the Source Data Administration Window is unchecked.
Configuration of the connection between EMarketOffer and your online databases of Transmission System data will be unique to your site. You should not attempt to create Connections without first consulting technical support both in your company and at Energy Link.
The typical EMarketOffer installation is configured to use file or database exclusively. However, if you want to switch between file and database sources for Transmission System data you will need to obtain the latest EM6/COMIT files and save them in the appropriate folders. You will also need to define the correct links to your online database sources.
To force the system to use the online database where EM6/COMIT files exist in the Grid folder:
- Shut down EMarketOffer
- Rename the EM6 and COMIT sub-folders to easy-to-remember names
- Re-start EMarketOffer
To force the system to use the transmission system data files again:
- Shut down EMarketOffer
- Return the renamed EMS and COMIT sub-folders back to their original names
- Re-start EMarketOffer
