Introduction to <strong>Simulator</strong> Add-On Tools<br />

In addition to the features of the base <strong>Simulator</strong> package, various add-on tools are available. A brief<br />

introduction to each follows:<br />

Voltage Adequacy and Stability Tool (PVQV)<br />

The purpose of the PVQV add-on is to allow the user to analyze the voltage stability characteristics of<br />

a system. After the PVQV simulation is complete, the user can graph various system parameters. For<br />

more information, see the PVQV Overview.<br />

Optimal Power Flow Tool (OPF)<br />

The purpose of an OPF is to minimize an objective (or cost) function . In <strong>Simulator</strong> OPF the Linear<br />

Programming OPF algorithm (LP OPF) determines the optimal solution by iterating between solving a<br />

standard power flow and solving a linear program to change the system controls thereby removing any<br />

limit violations. For more information, see the OPF Overview.<br />

Security Constrained Optimal Power Flow Tool (SCOPF)<br />

The OPF tool minimizes an objective function (usually total operation cost) by changing different<br />

system controls while meeting power balance constraints and enforcing base case operating limits.<br />

The SCOPF tool takes it one step further by considering contingencies that may arise during system<br />

operation and ensuring that in addition to minimizing the objective function, no unmanageable<br />

contingency violations occur. For more information, see the SCOPF Overview.<br />

Optimal Power Flow Reserves (OPFR)<br />

<strong>Simulator</strong> OPF Reserves is the tool used to simulate Ancillary Services Reserve Markets. For more<br />

information, see the Optimal Power Flow Reserves Overview.<br />

Available Transfer Capability Analysis Tool (ATC)<br />

ATC analysis determines the maximum MW transfer possible between two parts of a power system<br />

without violating any limits. For more information, see the ATC Analysis Overview.<br />

<strong>PowerWorld</strong> <strong>Simulator</strong> Automation Server (SimAuto)<br />

SimAuto provides <strong>PowerWorld</strong> customers the ability to access <strong>PowerWorld</strong> <strong>Simulator</strong> functionality<br />

within a program written externally by the user. The <strong>Simulator</strong> Automation Server acts as a COM<br />

object, which can be accessed from various programming languages that have COM compatibility.<br />

Examples of programming tools with COM compatibility are Borland Delphi, Microsoft Visual C++,<br />

Microsoft Visual Basic, and Matlab (among others). For more information on SimAuto, see the<br />

SimAuto Overview.<br />

Integrated Topology Processing<br />

Integrated Topology Processing allows you to solve EMS-type, full-topology models in a numerically<br />

robust and transparent manner. Integrated Topology Processing extends <strong>Simulator</strong> applications<br />

traditionally used by planners so they can operate in an operations real-time environment. For more<br />

information, see the Integrated Topology Processing Overview.<br />

Transient Stability (TS)<br />

Transient Stability analysis allows the analysis of system dynamic response to a fault on the system.<br />

For more information, see the Transient Stability Overview.<br />
