About this Manual
PowerWorld Simulator includes comprehensive, context-sensitive on-line help in addition to this manual. Using the
on-line help is strongly recommended, since it provides features not available in a printed manual, such as the ability
to jump to another topic. Furthermore, the on-line help is likely to be the more up-to-date reference as program
updates are issued.

Getting Started With PowerWorld
Introduction to PowerWorld Simulator
PowerWorld“ Simulator (Simulator) is a power system simulation package designed from the ground up to be user-
friendly and highly interactive. Simulator has the power for serious engineering analysis, but it is also so interactive
and graphical that it can be used to explain power system operations to non-technical audiences. With Version 11.0
we’ve made Simulator more powerful, more visual, and easier to use.
Simulator consists of a number of integrated products. At its core is a comprehensive, robust Power Flow Solution
engine capable of efficiently solving systems of up to 100,000 buses. This makes Simulator quite useful as a stand-
alone power flow analysis package. Unlike other commercially available power flow packages, however, Simulator
allows the user to visualize the system through the use of full-color animated oneline diagrams complete with zooming
and panning capability. System models can be either modified on the fly or built from scratch using Simulator’s full-
featured graphical case editor. Transmission lines can be switched in (or out) of service, new transmission or
generation can be added, and new transactions can be established, all with a few mouse clicks. Simulator’s extensive
use of graphics and animation greatly increases the user’s understanding of system characteristics, problems, and
constraints, as well as of how to remedy them.
The base package of Simulator is capable of solving power systems comprised of up to 100,000 buses. The base
package also contains all the tools necessary to perform integrated economic dispatch, area transaction economic
analysis, power transfer distribution factor (PTDF) computation, short circuit analysis, and contingency analysis. All of
the above features and tools are easily accessible through a consistent and colorful visual interface. These features
are so well integrated that you will be up and running within minutes of installation.
In addition to the features of the base Simulator package, various add-on tools are available. Please see Introduction
to Simulator Add-On Tools for more information.

Introduction to Simulator Add-On Tools
In addition to the features of the base Simulator package, various add-on tools are available. A brief introduction to
each follows:
Voltage Adequacy and Stability Tool (PVQV)
The purpose of the PVQV add-on is to allow the user to analyze the voltage stability characteristics of a system. After
the PVQV simulation is complete, the user can graph various system parameters. For more information, see the
PVQV Overview.
Optimal Power Flow Tool (OPF)
The purpose of an OPF is to minimize an objective (or cost) f unction . In Simulator OPF the Linear Programming OPF
algorithm (LP OPF) determines the optimal solution by iterating between solving a standard power flow and solving a
linear program to change the system controls thereby removing any limit violations. For more information see the OPF
Overview.
Security Constrained Optimal Power Flow Tool (SCOPF)
The OPF tool minimizes an objective function (usually total operation cost) by changing different system controls while
meeting power balance constraints and enforcing base case operating limits. The SCOPF tool takes it one step
further by considering contingencies that may arise during system operation and ensuring that in addition to
minimizing the objective function, no unmanageable contingency violations occur. For more information see the
SCOPF Overview.
Available Transfer Capability Analysis Tool (ATC)
ATC analysis determines the maximum MW transfer possible between two parts of a power system without violating
any limits. For more information see the ATC Analysis Overview.
PowerWorld Simulator Automation Server (SimAuto)
SimAuto provides PowerWorld customers the ability to access PowerWorld Simulator functionality within a program
written externally by the user. The Simulator Automation Server acts as a COM object, which can be accessed from
various programming languages that have COM compatibility. Examples of programming tools with COM compatibility
are Borland‚ Delphi, Microsoft‚ Visual C++, Microsoft‚ Visual Basic, and Matlab‚ (among others). For more
information on SimAuto, see the SimAuto Overview.

Getting Started With PowerWorld
What's New in Version 11.0
Simulator Version 11.0 boasts a number of major new features as well as a host of smaller enhancements designed to
improve the performance and convenience of the package. Simulator’s major new features include:
Graphical User Interface Changes
· Updated the look and feel of Simulator to match the latest platforms.
· Support of multi-monitor displays so that your onelines can be spread across your screens.
· New optional "free-floating windows" mode.
· Ability to use keyboard shortcuts to open oneline diagrams or AUX files at a single key stroke.
· More options for how log messages are generator so that you may format color and whether names/kv,
numbers, or both are used.
New Oneline Diagram Features
·
Unlimited Drawing Undo Feature
·
Added more abilities to the Select by Criteria dialog so that the c riteria may be based off advanced filters in
addition to area, zone, layers, and voltage.
·
Support for view 3-dimensional oneline diagrams.
·
The speed of rendering a large diagram has been greatly enhanced making the display of very large diagrams
possible. This includes a particularly large improvement for selected items.
·
Ability to resize and rotate oneline objects easily with your mouse.
·
Great enhancements for quickly formating your diagrams.
·
Added Dynamic Formatting of oneline objects and case information displays based on the system information.
·
Added the ability to specify with individual pie charts whether they show MW, MVar, MVA, PTDF, Amp, or Max
Contingency loading. You may then place different pie charts on the same transmission line.
·
Added more c olor options for pie charts based on what field they are showing.
·
Added ability to use special pie charts to highlight out-of-service transmission lines.
·
Added Translucent Image Support.
·
Added ability to specify whether a branch is "normally open". You may then color circuit breakers differently
based on whether they are normally open or not.
·
Added ability to optionally hide the circuit breakers on load, shunt and generator objects.
·
Emphasis of oneline objects using alpha-blending.
·
Added the ability to specify oneline options and contour information with a saved view.
·
New Line Gauge objects
·
Added the ability to embed a oneline inside of another oneline.
·
Made numerous options for how a substation object is displayed.
·
Enhanced the formatting of multiple selected objects so that you can change the field, rotation angle, and other
object characteristics.
·
Enhanced the default drawing values so that areas, zones, super areas and substations have their own
settings. This includes the ability to specify the default fields which should appear around the objects as they
are drawn also.
·
Added the ability to create contour color maps which map by value directly instead of going through the
percentage mapping between Maximum and Minimum values first.
·
This is a new option under the Option> to specify whether to "Show Field Suffixes". If you uncheck this option,
then the units which appear on most fields will be removed. Using this in conjunction with the "Include Field
Labels" option is encouraged.
Time Step Simulation for running multi-hour simulations
· Added a completely new tool for specifying the variation of values over time to create a time step simulation.
This can be done to model load changes, generation changes, line status changes, or really any value which
5
varies over time. You may then specify which values to track over time and these will be stored for use in
plotting after the time step simulation is run.
Geographic Information System Support
· Added to the PowerWorld Library of Borders to include Borders for the entire World.
· Added a new map projection for use with borders outside of North America (Mercator projection).
· Support for reading GIS ESRI Shapefiles.
· Added ability to split and merge background lines.
· Added ability to convert a background line into a transmission line, substation, or bus for use with GIS data you
may read.
· Added specification of a latitude/longitude coordinate with Bus and Substation objects.
New Data and Features
· Ability to specify that a specific AUX file be read at the end of reading any power system case. This can be
used to store default options you'd like applied to all cases.
· Increased the number of custom floating point numbers and strings from 3 to 5. Made the custom floating point
numbers double precision.
· Utilize Model Expression inside of an object's custom expression.
· Create a Model Filter which consists of other Model Filters and/or Model Conditions.
· Modified the Line Impedance Calculator to use the long-line model.
· Added ability to retain unlinked injection group elements and interface elements when reading them from an
AUX file so that you may better determine what has changed in your case.
· Added storage of the Case Summary Information and the case description to the Auxiliary File format.
· Added ability to scale by owner.
· Add the ability to specify Bus Group Calculated Fields.
· Areas, Substations, and Zones can now be left as empty. This allows you to create them first as empty and
then assign their contents.
· Modified the storage and setting of the "metered end" of a transmission branch. Previously when looking at this
value in a case information display it would only appear for area-to-area tie-lines. This has been changed so
that the value will always appear, but it will be shown as grayed out unless it is either an area or zone tie-line.
· Added a memo tab to most of the object dialogs in Simulator. These memos can be used throughout to
document your case in greater detail.
New Interface Dialogs
· Modified the Injection Group and Interface Case Information displays so you could more easily see what the
elements of the aggregations are.
· Greatly enhanced the auto-insert injection groups method so that they may generated by Area, Zone, Super
Area, Owners, or a selection.
· Added a tool to generate a list of branches which if taken out-of-service will split your system into islands. Tool
will also give you a list of buses that are islanded by this action.
· Two new case information displays have been added which show a list of all area-area tie-lines and all zone-
zone tie-lines in an entire case.
· Added option right-mouse button local menu option on the interfaces case information displays for automatically
creating reverse-direction interfaces from the selected interfaces.
Power Flow Modifications
· Added the ability to treat continuous shunts as PV buses.
· Nomograms can now be defined that exist in all four quadrants.
· Enhanced the angle-smoothing routine so that it works on any series of transmission lines which are closed in
together. Previously it would only operate when closing in a single line.
· Added ability to specify the minimum per unit voltage for which constant power loads are allowed. When a bus
voltage drops below this threshold the bus will gradually change into a constant impedance load as it
approaches zero per unit voltage.
6
Getting Started With PowerWorld
· Added log messages notifying the user when the impedance of a branch was changed due to the impedance
correction tables.
Contingency Analysis Changes
· New ways to visualize and export your contingency results.
· New contingency actions for opening/closing a 3-winding transformer.
· More contingency actions for Injection Groups, DC Lines, and Phase Shifters.
· Added contingency action for specifying the generator or switched shunt setpoint voltage.
· Ability to ramp an injection group up or down using "Merit Order" dispatch.
· Specify whether and how a generator’s MW output responds in the post-contingency solution.
· Modified the use of Model Criteria used in conjunction with contingency blocks. Simulator will now perform an
AND if a model criteria is specified at bother contingency block level and the individual actions inside the block.
· Modified the Combined Tables in Contingency analysis so that it also included columns for Contingency Owner,
Area, and Zone when they are shown in the Contingency Violation and Contingency Definition Tables.
· Added a new SUBDATA section "CTGElementAppend" to the objecttypes Contingency, CTGElementBlock,
GlobalContingencyActions, and PostPowerFlowActions. Actions inside these sections will be appended to a
definition instead of replacing the actions presently specified.
ATC Modifications
· Added ability to filter based on PTDF value separately from the OTDF.
· Increased the Maximum number of scenarios for each object type to 1024.
PVQV Modifications
· Completely updated the monitoring used in the QV Curve Tool to allow monitoring throughout the entire
system instead of only the terminal bus. This monitoring is the same as the PV tool now.
· Added QV -specific solution options.
· Modified the PV Curve tool to optionally use merit-order based ramping of the generation or load in an injection
group.
· Added ability to track more quantities in the PV and QV tools.
OPF and SCOPF Enhancements
· Greatly enhanced the speed of the linear program solution on large power system cases.
· Added the ability to dispatch two-terminal DC transmission lines in the OPF and SCOPF algorithms.
· Great improvement of the handling of phase-shifting transformers inside the DC optimal power flow. A better
coordination of the phase-shifters can improve or help insure convergence.
· Great improvement of the dispatch of Area-To-Area MW Transaction Controls to better handle situations where
they conflict with one another.

PowerWorld Interface
Windows Basics
Simulator 11.0 runs under Windows 95/98/2000/Me/XP and NT 3.5 and later operating systems. Since much of the
interaction between Simulator and the user is accomplished by using the mouse, we have designed the interface to
obey consistent conventions for mouse usage. In general, the left-mouse button is used to affect some sort of
immediate change or control over a power system element, while the right mouse button is used to gain more
information about a power system element or to view a list of available options. More details on mouse usage are
provided throughout this manual.

PowerWorld Simulator: Getting Started
The key to using Simulator is to recognize that it has two distinct modes Edit Mode and Run Mode. The Edit Mode is
used to construct new simulation cases or to modify existing cases, while the Run Mode is used to perform the actual
power system simulation. You can easily switch between the modes using the Edit Mode and Run Mode buttons on
the Program Toolbar.
If you are new to Simulator and seek a quick means of familiarizing yourself with it, we recommend starting with the
tutorials; see Creating a New Case or Starting with an Existing Case
Sample cases are provided with the software in the "Sample Cases" directory. If you’re interested in trial-and-error
learning, you may wish to open one of the sample cases and start learning.

Edit Mode Introduction
The Edit Mode is used to create a new case or to modify existing cases. To switch to Edit Mode, click on the Edit
Mode button on the Program Toolbar, or choose File > Switch to Edit Mode from the file menu.
Here is a sampling of things you can do in Edit Mode:
· Create a new case; see New Case for details.
· Create a new oneline diagram; see New Oneline for details.
· Add new components graphically to an existing case; see Insert Menu for details.
· Modify the appearance of the oneline objects; see Format Menu for details.
· View and modify a case using non-graphical lists displays; see Case Information Displays for details.
· Equivalence a case; see Equivalencing for details.
· Append a subsystem to an existing case; see Appending a Case for details.
For more details on the Edit Mode please see Edit Mode Overview.

Run Mode Introduction
The Run Mode is used to solve a single Power Flow Solution, run one of the available load flow tools, or run a time-
domain simulation of the power system. To access the Run Mode, click on the Run Mode button on the Program
Toolbar, or choose File > Switch to Run Mode from the file menu.
The key menu associated with the Run Mode is the Simulation menu. This menu allows you to perform a single
Power Flow Solution (however, it is quicker to use the toolbar).
Other key components of the Run Mode include:
· The oneline diagrams, which allow you to view the case graphically. See Oneline Diagram Overview for details.
· The Case Information Displays, which allow you to view the entire power system case using list displays. See Case
Information Displays for details.
· Dialogs to change the simulation options and the Power Flow Solution. See Simulation Options for details.
· Scaling to allow easy variation in the load, shunts, and generation at any number of buses. See Scaling for details.
· Contouring, which shows a color contour representing the variation in any power system parameter across a system.
See Contouring for details.
· Transfer distribution factor calculations. See Power Transfer Distribution Factors for details.
· Perform a fault analysis. See Fault Analysis for details.
· Run Transfer Capability studies.
· Perform an Optimal Power Flow (OPF) or Security Constrained Optimal Power Flow (SCOPF) analysis.
· Generate PV and QV curves.

Script Mode Introduction
The Script Mode is used to access the Script Command window. Simulator scripting allows a method of grouping
multiple commands for sequential processing by Simulator. From the Script Command Execution window, the user
can manually enter script commands for processing, or load an auxiliary file containing multiple script commands and
data modification commands.
Some features in Simulator are available exclusively in either RUN mode or EDIT mode. This functionality is
preserved in the script language, but with the addition of a submode feature. Submodes determine which script
commands can be called. Only those commands available to the current submode can be executed. You will always
be in one of the submodes when executing a script. If the Script Command Execution Dialog is opened from Edit
Mode, Simulator defaults to the EDIT, CASE submode. If the Script Command Execution Dialog is opened from Run
Mode (or when a script is initially started), Simulator defaults to the RUN, POWERFLOW submode.
To switch submodes, use the EnterMode (mode or submode) script command. The following list includes the
submodes available to each of the Simulator modes. Click on the links below to see the actions available to each
mode and/or submode.
Edit Mode
· Case Submode
· Run Mode
· PowerFlow Submode
· Contingency Submode
· ATC Submode
· Fault Submode
· PV Submode
· QV Submode
There are also a number of general script actions that can be executed in any of the submodes. See Script General
Actions for more details.

Message Log
The Message Log displays detailed results of each Pow er Flow Solution, chronicling the solution process iteration by
iteration. It also reports messages raised by Simulator in performing various operations, such as opening or validating
a case. The Message Log can be helpful when you run into problems solving a particular simulation case. The
Message Log is not used with Viewer.
To display the Message Log, click on Log on the Program Toolbar.
Right-clicking on the Message Log displays its local menu. To change the font characteristics of the log, select
Change Font. To suppress or change color of certain messages associated with the power flow case select either
Suppress Messages or Color Messages and then the desired message whose characteristics want to change. To
print a highlighted section of or clear the log, select either Print Selection or Clear . You can find a certain text by
clicking on Find, and then entering the text in the dialog displayed. Also, you can highlight all the text in the log, or
inversely unselect all the highlighted text by clicking on Select All, or Unselect All, respectively. To print or copy the
contents to the Windows clipboard of a highlighted section of the message log, select Print Selection or Copy
Selection to Clipboard. You can also clear the contents of the log by selecting Clear . Lastly, you will find some log
options available, such as Change Maximum Lines, Disable Logging and Save Log to File options which allow
automatically saving the log to a file during load flow analysis.

Web Publishing
Simulator provides tools for creating presentations of data and diagrams produced using the application for display on
the world-wide web. These tools include
· The ability to save case information display contents as HTML code.
· The ability to save oneline diagrams and strip charts as jpeg files. See Saving Images as Jpegs for more information.
· A basic HTML editor that can import HTML code written using other applications.
· A mechanism for uploading your HTML documents to your web server. See Publish to Web for details.
Consult the chapter on Web Publishing for more information on how to publish your Simulator data on-line.

Memo Display
The Memo page is now available on many dialogs and displays in Simulator. The purpose of the memo display is to
allow the user to add their own custom information and comments to data and objects in the load flow case. Simply
switch to the Memo page on a display and start typing in the memo box. The information added to these memo pages
is stored with the objects in the load flow case.
