Model Management Module FREE one month trial
Centrally manage all of your PSS®E data, files, projects, changes, etc. across multiple users and time horizons – from directly within PSS®E. Lightweight, easy to use, and barely any IT burden to deploy. Instantly construct and validate scenarios and basecases on demand. This can be used to functionally replace the “Open Case” step in PSS®E with a “Load Model Definition” step. It allows you to record projects directly in PSS®E (editing the network data through the datagrids or slider diagrams), and add these project definitions directly into the model database. The module supports a batch mode for streamlining model series development for regional model development efforts and automatic next-day model building for operations studies. Also, it is fully scalable and suitable for any size modeling team – big or small.

Graphical Model Builder (GMB)
Graphical Model Builder (GMB) module is a powerful and easy to use dynamics model development tool based on graphic representation of control block diagrams. Accurate power system planning requires that precise models be used in the simulation software. PSS®E software is designed for dynamic modeling of complex systems. GMB allows specialized modeling by supporting both standard and non-standard dynamic models.
Data Visualization and Reporting Module FREE one month trial
Provides PSS®E users with new ways of interacting with their power flow and dynamics output data, and simplifies the analysis and visualization of these results.

PSS®E-PSCADTM Co-Simulation (E-Tran Plus for PSS®E) FREE one month trial
Hybrid simulation interface between PSCADTM EMT and PSS®E transient stability applications. Allows complex PSCADTM models to communicate with a PSS®E transient stability time-domain simulation. The PSCADTM side system equivalent gets updates from PSS®, and the PSS®E side gets updates from the in PSCADTM models at each time step. This hybrid simulation allows dynamic system equivalents in PSCADTM, more accurate model behavior in PSS®E, and different versions of PSS®E running simultaneously.

Transfer Analysis and Sensitivities Module*
Integrates the functionality of MUST directly into PSS®E. We’ve also made extensive performance/stability improvements, and added new functionality based on user feedback: ATC/ATF calculation, flowgate generation, new Python GUI, and completed Python API.* Coming in 2017
The PSS®E Dynamic Simulation module is a versatile tool to investigate system response to disturbances that cause large and sudden changes in the power system. The dynamic simulation module employs a vast library of built-in models for modeling different types of equipment, and with capability to create user defined models of any complexity. An integrated dynamic simulation plotting package allows for quick generation of plotting with ability to export to several popular graphic formats.
Geomagnetic Induced Currents (GIC)
Power system planners and operators require technical tools to conduct studies to assess the impact of GIC currents in the power grid and prepare mitigation measures. The value added GIC module for PSS®E meets their requirement using the latest method of calculation recommended by NERC. The method used is the induced voltages in transmission lines from the voltage sources.
Eigenvalue and Modal Analysis (NEVA)
Stability problems, such as inter-area oscillations, have become increasingly common in large interconnected power systems. The Eigenvalue and Modal Analysis (NEVA) module provides an extension of analytical methods to examine these oscillations. Used with the PSS® Product Suite, the NEVA module provides methods to investigate long-term stability, allows a deeper view into eigenvectors, determines the best damping locations, and allows evaluation of damping strategies.
Optimal Power Flow (OPF)
The Optimal Power Flow (OPF) module goes beyond traditional load flow analysis to provide the ability to fully optimize and refine your transmission systems. OPF improves the efficiency of power system performance studies by adding intelligence to the load flow solution process. Whereas the conventional load flow relies on the engineer to systematically investigate a variety of solutions before arriving at a satisfactory or good solution, OPF automatically adjusts controls to determine the best solution.
Short Circuit Calculations
PSS®E Short Circuit module has a number of short circuit calculation algorithms to meet the diverse needs of fault analyses. All algorithms are self-contained analyses in PSS®E. They require a valid power flow working case and the power system sequence data.
Transmission Line Calculator / Line Properties Module
The Transmission Line Calculator module calculates branch impedances from line geometry models. Also known as the Line Properties Module.
