Create a simulation of a power system and analyze its work. Select specific power flow cases and monitor them across the simulation, exchange them between different flow paths, animate and visualize the system functionality. Generate reports based on monitored data.
This program was designed to make it easy to exchange power flow cases. You can view a solved power flow case graphically using animated one-lines. Some example one-lines are included in the download and additional examples are available at the FERC 715 Filings page.
v18.2 [Jan 8, 2015]
The following is a list of many of the most noticeable changes in Simulator Version 18, which builds on PowerWorld Corporation’s dedication to creating powerful, easy-to-use analysis software. Version 18 contains many new features and enhancements to improve the performance and convenience of the package.
Auxiliary Files and Display Auxiliary Files
- Added a special SUBDATA section “BusRenumber” to a multi-section line records which allows you renumber the dummy buses in the multi-section line by using the same format as for specifying the dummy point.
- Added ability to write out the “REVERSE” bids for a StudyMWTransactions object. Previously you would only see the area-to-area MW bids from the lowest area number to the highest when saving out to an AUX file.
- If loading in an auxiliary file with REMOVED object types, i.e. REMOVEDBUS, REMOVEDBRANCH, etc., the corresponding objects will be deleted in you are in Edit mode. REMOVED object types that are supported are any object that can be compared in the topological differences as part of the Difference Flows tool.
Auxiliary File SCRIPT and SimAuto
- Can now use the keyword ALL instead of using the location number of a field when specifying variablenames as part of a field list used with select script actions. This will return all fields with the same variablename. This is intended to allow easier access to fields when the exact number of fields is not known such as with multiple TLR (MultBusTLRSens:ALL) or PTDF (LinePTDFMult:ALL) results. This can be used with SaveData, SaveDataWithExtra, SaveObjectFields, and SendToExcel script actions.
- Can now use the keyword ALL instead of a variablename as part of a field list used with select script actions. This will return all fields for a particular objecttype. This can be used with SaveData, SaveDataWithExtra, SaveObjectFields, and SendToExcel script actions.
- Added new script command SetInterfaceLimitToMonitoredElementLimitSum(filtername) where the filtername is a filter that applies to interfaces that should be adjusted by the command.
- Added script commands RenumberBuses, RenumberAreas, RenumberZones, and RenumberSubs, each with a parameter denoting the number of the Custom Integer field containing the new numbers.
- Added script command ConditionVoltagePockets(VoltageThreshold, AngleThreshold, Filter). The goal of this script command is to find groups of radial buses that may have bad initial voltage estimates and to get a better voltagestimate of these buses based on assuming that the voltages on buses outside of the radial group are good. It will identify pockets of buses bounded by branches that meet the condition that the absolute value of the voltage difference across the branch is greater than VoltageThreshold or the absolute value of the angle difference across the branch is greater than AngleThreshold and the branch meets the specified filter. The buses contained within these pockets will have their voltages estimated based on the assumption that the voltages at buses outside these pockets are good. The Filter is optional and determines which branches will be examined. If not specified all branches are considered.
- Added script action CTGRelinkUnlinkedElements. This does exactly what they name implies.
- Added a new script command ExportAreaSupplyCurves(“filename.csv”, “User Defined String”, NumPoints); The first parameter is the name of the CSV file to which results will be written. The second parameter is an optional parameter for specifying a user defined string written to each entry in the resulting CSV file. If the second parameter is omitted, a blank will be assumed. The third parameter is optional and is related to converting a cubic cost model into a piece-wise linear model. If you omit the second parameter we assume 5. The output of the file will have 7 entries for each area for Fixed Gen MW, Fixed Load MW, Fixed Shunt MW, Losses MW, Variable Min MW, Variable Max MW, Variable Present MW, followed by a set of Bid MW/Price entries representing the supply curve for the variable MWs.
- Added new script command InitializeGenMvarLimits. This initializes all generators in the case so that they are appropriately marked as being at Mvar limits or not. This could be useful if manually setting the Mvar output of generators or changing their limits.
- Added new script command SaveGenLimitStatusAction(“filename”). Use this action to save Mvar information about generators in a text file. The information saved includes the generator bus number, generator ID, Mvar, Max Mvar, Min Mvar, AVRable flag (user specified), and internal AVRable flag (set by Simulator). This information is useful for debugging.
