Example Run Window

Run Parameters Box

This is located at the top left and contains general Run Parameters.

Run Parameters Box Fields

Connections	Specifies the Connections Resource to be used
Start Date	The Run will begin at 00:00am on this date.
Demand Regions	specifies which Demand set ( Regions Resource) is to be used
Dispatch Mode	One of three pre-defined settings determining the method used to solve the dispatch problem: Nodal: nodal pricing with energy dispatch only (the most commonly used dispatch mode) Nodal+Reserves: energy and Reserves dispatch co-optimisation. Simple: simple merit order dispatch method in which transmission losses and limits are ignored, i.e. Offer Bands are dispatched solely on the basis of their price, in the order of lowest to highest. In simple mode all 'nodal' prices throughout the country will be the same for any particular Tick.
Reserve Config	Specifies which Reserve Resource is to be used - however this is only effective when Nodal+Reserves is selected in the Dispatch Mode field.
Company Opt	When set to True any company in the Connections Resource set to Optimise Offers will have company optimisation implemented. . That is, the Company's exposure to Prices from retail load, to hedges, and market power are used to adjust the Company's Offers in order to optimise gross profit. If this option is set to False, then no company optimisation adjustments will be made.
Binary Outputs	Specifies which Binary Output set is used.
Reports Batch	Specifies the Reports Batch Resource which defines the Reports automatically produced with the Run. If no Reports Batch is attached, then no Reports will be produced automatically at the end of the Run. But note that Reports can be updated and produced at any time, via the Reports Resource.
Random Outage Seed	Determines the pattern of random Generator outages for a Run. Version: tells the Run to use every combination of variables defined in the 'Volatility Matrix box as an outage seed. For example, if the variable Inflow Year has values 1931-1932, and variable V2 has value 1, then there will be the generation outage pattern will be consistent from Run to Run with the setting 'Version' if no other changes have been made to the Run setup. This is the setting you will probably use the most. Rand: causes the outage pattern to be random for any Generator with an Availability less than one. Constant: forces a particular outage pattern to occur for a Run every time it is submitted regardless of changes to any setting for that Run. However, it is unlikely that Runs created with different input data will have the same outage pattern with this setting. As well the three pre-defined fields, variables from the Volatility Matrix are also available as seeds. These variables appear along with the pre-defined seeds in the field's selection list (the Inflow year option will be a frequently used example).

Demand Box

The Demand Box is used to set the annual Demand (in GWh) associated with each Region in the Regions Resource specified in the Run Definition.

Demand Box Fields

Region	each Region field lists a Region that has been setup in the Regions Resource. The Region names cannot be edited from this box
Demand (GWh)	Specifies the Demand figure in GWh against each Demand Region.

Schedules Box

Schedules allow you to control various aspects of the model at run time. Using a Schedule Resource in a Run is optional, but any Schedules used must be listed in the Schedules Box.

Schedules Box Fields

Name	Specifies which Schedule Resource is to be used
Description	A free text field for supplementary information about the Schedule Resource

Note: Multiple Schedule Resource Instances can be used in a Run Definition. Where the same constant, variable or function is used in different Schedules associated with a Run, EMarket will use the last definition to be read for that constant, variable or function - no warning will be given that this has taken place.

Volatility Matrix

The Volatility Matrix enables you to model volatility associated with various aspects of the electricity market (e.g. price and volume volatility).

More rows for more variables can be added by clicking on an existing row and pressing <insert>.

Volatility Matrix Fields

Variable

A user-defined name for the volatility variable. This variable can be used in any field where a formula can be entered.

Values

Specifies the variable values that will be applied to the Run. This field can be specified as: a consecutive series, e.g. 1-10 indicates that there will be 10 values, 1,2...9,10 a group of values, e.g. 2,4,7,11 indicates there will be 4 values.

In defining the variables N1, N2, … Nm, the Run will actually output N1 × N2 × …× Nm data series in total, each with a different combination of the variables' values. With this feature, large numbers of scenarios can be set up and run quickly and easily.
