Multiple Scenario ATC Dialog: Scenarios
The Scenarios page of the Multiple Scenario ATC Analysis is available on the Available Transfer
Capability Dialog when selecting the option to Analyze Multiple Scenarios on the Advanced Options
tab of the Available Transfer Capability dialog.
By defining multiple scenarios, Simulator allows you to calculate ATC values for several different power
system states automatically. Scenarios can be modified along three axes:
Line Rating/Zone Load Scenarios (weather-related scenarios)
Generation Scenarios (generation profiles)
Interface constraints
Each of the different scenario types can be defined on its own tab. Each tab contains a list of the
power system elements that will be modified during different scenarios. These lists are a familiar Case
Information Display providing the same functionality as other displays.
To insert a new power system element into the list, right-click on the list (below the headings) and
choose Insert.
If a power system element does not show up in one of the lists of elements for a particular scenario,
then it will retain its base case value during that scenario.
When saving or loading scenario elements in an auxiliary file, the elements are usually identified by
primary key fields. Optionally, these elements can be identified by label. See the Label topic for more
information about this.
Line Ratings/Zone Loads Tab
Use this tab to define Line Ratings and Zone Loads scenarios.
Line Ratings and Zone Loads are varied together when analyzing scenarios. This was chosen
because they often vary together as a function of the weather. Notice that three sub-tabs (labeled
Line Ratings A, Line Ratings B, and Zone Loads) appear at the top of the Line Ratings/Zone Loads
tab.
Line Ratings A and B
