Viewing the Optimization Report
Right click an Optimization event row in the Work Agenda and select the Optimization Report option. The Optimization Report tab opens in the Event Details window with its list of feeders affected and recommended solution.

Plan Details for more information.
Understanding the Summary Pane
The Summary pane shows details for the plan and represents high level details for the optimization area. Before a plan is executed only the Before and After (Estimate) details will be populated. Once a plan has been executed and the power flow resolved, the After (Actual) will be populated. By showing both the estimate and the actual, you can compare the results to determine if any adjustments need to be made to the underlying DMS data (for example, inaccurate load profiles creating incorrect estimates).
Summary Information
• Min Volt (%): The minimum service voltage in the optimization area.
• Avg Volt (%): The average service voltage in the optimization area.
• Max Volt (%): The maximum service voltage in the optimization area.
• Loading: The total loading in the affected area showing both real and reactive power.
• % Reduction (kW): This value will be displayed when Conservation Voltage Reduction, Loss Minimization, or Relieve Overloads objectives are selected. For Conservation Voltage Reduction or Relieve Overloads, it will display the percent change in reduced demand. For Loss Minimization, it will display the percent change in reduced losses.
• PF Change: This will only display for the Power Factor Correction objective and will display the change in power factor.
• % Voltage Change: This value will be displayed for the Maximize Voltage objective. It will display the percent change in maximum voltage by executing the optimization plan.
• % Increase (kVAr): This value will be displayed for the Maximize VAr objective. It will display the percent change in reactive VAr support by executing the optimization plan.
• DER Gen: The total DER output in the optimization area for real and reactive power.
• Losses (kW): The total losses in the optimization area.
• Power Factor: The overall power factor for the optimization area.
Note: Power factor will be negative for leading and positive for lagging.
• Violations: The total number of violations in the optimization area.
• Warnings: The total number of warnings in the optimization area.
Optimization Messages
The Optimization Messages section displays pertinent information related to an optimization event. This section is displayed in a tabular format with configurable and translatable messages. The messages contain error information as well as general information such as timing to execute a plan, to create the plan, to update a plan, and so forth. This dialog box also has a related context menu that lets you navigate to devices mentioned in the messages.
Recommendation Plan
This section of the report gives details of the plan, including Substation, Feeder, and Device level information. The device level information shows the before and after position settings as determined by Optimization.
Select a device row, right-click, and select View...to launch the Viewer with the device in focus.
Plan Details
The Plan Details window has a Feeder pane and a tabbed pane that displays information about a selected feeder.
Feeders Pane
The Feeders pane lists all of the feeders affected by a solution and provides details about load and violations before and after the optimization plan is executed. Before a plan is executed only the Before and After (Estimate) will be populated. Once the optimization plan has been executed and the power flow resolved, the After (Actual) values will populate.
Tabbed Pane
When you select a feeder from the Feeders list, the following tabs are displayed:
• Violations: shows any violations associated with the selected feeder. To focus the Viewer on the device associated with the violation, select a violation in the list and click the View... button.
Note: The View... button is enabled whenever a violation node is selected.
• Voltage Profile Graph: this graph shows the voltage profile along the feeder representing voltage at each service point for before (displayed gray) and after (displayed blue) plan execution. This shows you the graphical voltage drop that occurs on the feeder and also shows you how the voltage profile will be raised or lowered at different sections as a result of implementing the plan.
Note: The Voltage Profile Graph differs slightly for real-time usage and will overlay any bellwether meters voltages present. The before bellwether meters will be colored pink and the after bellwether meter voltages will be green.
• Voltage Distribution Graph: this graph displays the voltage distribution in the form of a frequency plot on the affected feeders. The before results are displayed in gray and after results in blue.
• SCADA Measurements: displays before and after measurements for SCADA telemetered devices within the optimization area. If the plan has not been executed, only the before values will display; once a plan is executed the after values will be populated. This table allow you to view loading and bellwether meter voltages before and after the optimization.
If you select a row in the SCADA Measurements table, the right-click context menu provides options to open the SCADA Summary (SCADA Summary...) or view the selected device in the Viewer (View...).
