PV Curves Results: Overview
The Overview sub-tab is found on the PV Results tab of the PV Curves dialog. This page provides a
summary of all scenarios studied and their results. This table will update as the analysis progresses.
The overview is a case information display and therefore can be used in a manner consistent with all
other case information displays.
There are a number of fields that are shown by default on the display:
PV Scenario
Name of the scenario. Either base case or the contingency name.
Critical?
YES if the scenario is considered to be critical. Otherwise, NO.
Critical Reason
This will be blank as long as the scenario is not critical. If the scenario is critical, there are a number
of reasons that could be displayed explaining why the scenario is critical:
Reached Nose - The power flow failed to solve so the system is considered to be at the nose of the
PV curve.
Inadequate Voltage - The process stopped because at least one voltage is considered inadequate.
This reason will only occur when using the option specified on the Limit Violations tab to Stop
when voltages become inadequate. The message will be appended with the bus and voltage of
the bus with the lowest inadequate voltage.
Source Maxed - The source no longer has enough resources to continue the power transfer.
Source resources are affected by the options Enforce unit MW limits and Do not allow
negative loads found on the Common Options sub-tab of the Setup tab. They could also be
affected if choosing to use merit order dispatch in which unit limits are always enforced.
Sink Maxed - The sink no longer has enough resources to continue the power transfer. Sink
resources are affected by the options Enforce unit MW limits and Do not allow negative loads
