The Post Power Flow Solution Actions dialog describes a list of actions that are executed at the end of every Full AC power flow solution, which means they are not performed for DC solutions. Normally, these actions would all have Model criteria specified.
To open this dialog, select Simulator Options from the Case Options ribbon group on the Options ribbon tab. Next, go to the Power Flow Solution category. Then click on the Advanced Options. Finally click the button labeled Define Post Power Flow Solution Actions.
Check the Do Not Used Post Power Flow Solution Action List check-box to disable using any actions defined in the list.
The action list display identifies the actions that comprise the post power flow solution action list. Actions can be inserted or deleted by using the local menu on the dialog. Right-click on the display and select Insert or Delete. Actions are inserted via the Contingency Element Dialog.
The action display is a type of Case Information Display and thus shares many characteristics and controls common to all other case information displays.
The Action List Display always contains the following fields:
Actions
This shows a string which describes the action. You may customize the format of the string that describes the actions by right-clicking on the Action List Display and choosing Display Descriptions By, and then choosing either Name, Num, Name/Num, PW File Format by Numbers, PW File Format by Name/kV or PTI File Format.
Model Criteria
Simulator allows you to define Model Criteria, which consist of both Model Conditions and Model Filters. These specify a criteria under which a contingency action would occur. For example, you could specify that a generation outage only occur if the pre-contingency flow on a line is higher than a specified amount. Normally, no Model Criteria will be specified, and this field will be blank. Also, note that Model Criteria can be overridden by the Model Condition and Filter option on the Contingency Options Tab. You can open a dialog to define Model Filters or Conditions by right-clicking on the Action List Display and choosing Define Model Criteria.
Status
The following options are available for this field:
- CHECK : The action will be executed only if the Model Criteria is true. It will also be executed if no model criteria is specified. This is the default setting
- ALWAYS: The action will always be executed, regardless of the Model Criteria.
- NEVER: The action will never by executed, regardless of the Model Criteria.
- POSTCHECK: This action is checked AFTER the other Check and Always actions have been performed and the load flow solution solved. If the criteria specified for the Postcheck action are met in the resulting load flow solution, then this action is taken and the load flow is again resolved. This will recursively occur for all Postcheck actions until either all postcheck actions have been taken, or the criteria for all remaining postcheck actions have not been met.
Note that the Never action allows you to disable a particular action without deleting it.
Comment
A user-specified comment string that can be associated with this action. While this comment is not used by Simulator in any way, these comments can be saved to be loaded at a later time. This is provided for the user to add comments regarding the action. For example, for an action with a Model Criteria you may could add a sentence explaining why the action is only performed under the specified criteria.
