Extended tools for allowing PSS®E users to perform strong power flow and contingency analysis customizations, including the ability to model Remedial Action Schemes (RAS) and Special Protection Systems (SPS). Includes fast PSS®E contingency analysis results APIs, contingency results to database APIs, power flow and contingency analysis Python extension framework and functions for complex, user-defined RAS and SPS schemes.

Today, with smart technologies and alternative energy resources, our power grid is changing constantly. To stay current, users need to determine the transmission transfer capability by simulating network conditions with equipment outages during changing network conditions and by simulating generation dispatch in an efficient manner. Power system planners and operators are typically using in-house, excel-based, and nonintegrated tools that can be error prone and time consuming to update. Building on the basic linear analysis capabilities in PSS®E, the new PSS®E Advanced Linear Analysis add-on module enables you to calculate linear distribution factors and determine analytics about your network topology to perform transfer limit analysis, security constrained economic dispatch, advanced contingency analysis and impact and sensitivity analysis.

Easily automate your NERC TPL-001 compliance process. The new module enables you to perform a fully automated NERC TPL-001 analysis with PSS®E using just your base case – meaning contingency definitions are generated automatically, and consistent reports for evidence of compliance can be easily produced.

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.

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 this requirement using the latest method of calculation recommended by NERC. The method used is induced voltages in transmission lines from voltage sources.

Easily determine and compare harmonics distortion levels to industry standards

The proliferation of renewables (Inverter Based Resources) in the power system is increasing the number of Harmonic Distortions. Network planners, such as yourself, now need to consider Harmonic distortions, according to industry standards, to better prepare mifor tigatory actions detrimental to system operations and power quality. With the new Harmonics add-on module, you can now:

• Easily analyze harmonic distortion levels and perform a frequency scan
• Compare generated harmonic results with industry standards using user-defined filters
• Review potential impact on equipment

Accelerate simulation performance on-demand with the power of the cloud for on-premise

It is now easier than ever to access the power of the cloud and tackle the growing number of simulation requirements. The Hybrid Cloud module enables users to accelerate simulation performance directly from their on-premise version. It is now available for users in North America on PSS®E 36.2 and above.

• Unlock on-demand cloud power to accelerate simulations by up to 30x, ensuring optimal performance for time-sensitive projects and variable workloads.
• Avoid the IT burden with seamless access to cloud resources within PSS®E on-premise, eliminating the need for extra IT infrastructure deployment or costs. It uses your existing infrastructure and integrates into your regular operational workflows.
• Effortlessly integrate the cloud into your simulations with a click of a button or by adding the new cloud APIs into your existing scripts.

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.

Optional add-on module for PSS®E that provides up to 25 x speedup of dynamics simulations on a single workstation. It allows you to run multiple simulations in parallel by deploying a single simulation on each CPU core/thread of your workstation. This allows you to accomplish in minutes what normally takes hours! Easy to deploy – simple installation with no IT burden. Easy-to-use – immediate benefits, without a big learning curve.

Automate the analysis of power flow simulations considering multiple time-points

In the past, short-term planning studies considered only a limited set of data, such as static peak and off-peak data. This is no longer sufficient as the grid becomes more dynamic and less predictable. Planning studies need to consider more time points to drill down to the actual worst-case scenarios.By introducing time-series data into planning studies, planning engineers can increase the accuracy of short-term planning decisions (outage planning/operations planning) based on more realistic scenarios.With the new Time-series Power Flow add-on module, you can now:

• Define detailed load and generation profiles for any time interval (e.g. minutes, hours, days)
• Automate the creation of cases and streamline the solving of hundreds of thousands of power flow solutions
• Intelligent post-processing to identify revealing trends and outliers to pinpoint worse cases for further analysis

The Graphical Model Builder (GMB) module, powered by PSS®SINCAL Platform, 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.

Hybrid simulation interface between PSCAD EMT and PSS®E transient stability applications. Allows complex PSCAD models to communicate with a PSS®E transient stability time domain simulation. The PSCAD side system equivalent gets updates from PSS®, and the PSS®E side gets updates from the PSCAD models at each time step. This hybrid simulation allows dynamic system equivalents in PSCAD, more accurate model behavior in PSS®E, and different versions of PSS®E to run simultaneously.

Directly translate PSS®E network models into high fidelity PSCAD electromagnetic transient models. Complex PSCAD machine and HVDC models can then be integrated into this network model for sophisticated analysis. PSS®E and PSCAD are the most widely used and trusted tools in their respective domains – now you have the ability to simplify and streamline your workflows involving these two tools.
