Contingency Element Type: Solve Power Flow

See Also

 

The following describes the options available when creating a contingency element of type Solve Power Flow. Contingency elements are created from the Contingency Element Dialog, and additional details of how to create contingency elements can be found here.

 

Action Settings

The solve power flow type is unique in that you can include an action that forces Simulator to solve the power flow as part of the contingency. There are rare special cases of sophisticated contingency definitions this can be used for, as requested by one or more PowerWorld customers. The load flow is already generally solved for each contingency as part of the processing.

If a contingency has one or more Solve Power Flow actions, then there will be a few changes in how the contingency definition display behaves.

• Sorting of the list of actions is no longer allowed. This is because the order of the actions is now important to how the contingency is processed.
• When you right-click on the list of contingency actions there will be two new options for Move Up and Move Down. These can be used to reorder the actions.
• On the Contingency Definition Dialog, there will be up/down arrows on the right of the dialog that may be used to reorder the actions.

Implementation

Solve power flow actions impose an order in which actions are applied. Groups of actions that are applied together are separated by Solve Power Flow actions. The Status of an action will dictate how it fits into this order. TOPOLOGYCHECK actions will ignore this order and be checked and applied as necessary with each group of actions. Any CHECK actions that are part of Global Actions or Remedial Actions will be checked and applied if necessary in the first group of actions. POSTCHECK actions will be checked and applied if necessary after all groups of actions have been applied.
