Time Step Simulation: Summary

Concept Link IconSee Also

 

The Summary page of the Time Step Simulation dialog is used to define the time points and display a summary of the simulation. Most of the commands to manage time points can be accessed from the Summary page local menu.

Once time points are defined, the Summary page presents the following columns for each time point:

Date

The date of the time point. To modify the date, right-click and select Time Point records > Change Timepoint Time on the local menu. This will open the Change Timepoint Time Dialog.

Time

The time of the time point to the second. To modify the time, right-click and select Time Point records > Change Timepoint Time from the local menu. This will open the Change Timepoint Time Dialog.

Skip

Set this field to YES to include the time point in the simulation. If set to NO, the input data and any scheduled actions that occur at this time point are not applied to the power system.

Processed

This field is set to YES if the simulation has processed the time point. This includes applying the input data, applying the scheduled actions, and solving the power flow for that particular time point.

Solution Type

The time point can be solved using one of the following Solution Types: Single Solution, Unconstrained OPF, optimal power flow (OPF), and security-constrained optimal power flow (SCOPF). The last three solution types require the Simulator OPF/SCOPF add-ons. See Running OPF and SCOPF Time Step Simulations for more information.

Run Contingencies

If the case has a defined set of contingencies, you can choose to run the contingency analysis for each time point by setting this option to YES.

Solved

This will be set to an integer value indicating at what point a solution was obtained for the time point under the specified Solution Type.

Num Loads

Total number of loads for which input data has been specified.

Total MW Load

Total MW load specified as input data for the time point.

Total Mvar Load

Total reactive load specified as input data for the time point.

Num Gens

Total number of generators in the system for which input data has been specified.

Total MW Gen

Total MW of generation specified in the input data.

Pre Script Cmd

The Time Step Simulation has the capability of running a pre script command before each time point is solved. The pre script command can be run either before applying the input data and scheduled actions or right after applying the input data and scheduled actions but is always run before the power flow solution is solved. See Time Step Simulation: Options for more information on specifying when the pre script command is run. See the Script Command section to learn the details about performing Simulator actions using script commands.

Post Script Cmd

The Time Step Simulation has the capability of running a post script command right after the time point is solved. The post script command can be run either before storing results or after storing results. See Time Step Simulation: Options for more infomration on specifying when the post script command is run. See the Script Command section to learn the details about performing Simulator actions using the script language.
