PSS®ODMS – CIM-based transmission network modeling and analysis software

PSS®ODMS – your CIM-based transmission network modeling and analysis software

PSS®ODMS closely aligns real and virtual worlds – enabling you to utilize a single source of truth for all of your network modeling and analysis needs

Transmission operations studies and analyses are only as good as the data or models on which they are based. With the PSS®ODMS multipurpose solution, you can easily create, manage, validate, and exchange network models for use in long-term planning studies, near-term operational planning, and real-time system operation.

Event news | Coronavirus

Coronavirus impacts on upcoming PSS® User Group Meetings

In consideration of the recent health and safety concerns around the Coronavirus and related travel restrictions, the planned in-person 2020 U.S. and European PSS® User Group Meetings will be replaced with several engaging virtual sessions.

While face-to-face engagement with the PSS® community is ideal, the virtual sessions will enable PSS® users to keep up to date with the latest product developments and have focused discussions directly with the product experts. The exact dates and registration information will be provided to customers in the near future.

PSS®ODMS software

Unique benefits for every application

Seamless data management and exchange across multiple utility domains

By designing and deploying a standards-based network model management solution, AEP can leverage emerging industry technologies around data management and data analytics.
Eric Hatter, T-Nexus program manager at American Electric Power

Automated, repeatable, and accurate production of solved forecast cases

Achieve ENTSO-E requirements to ensure interoperable data exchange

Anticipate, assess, and mitigate real-time issues without deploying a full EMS

Save time, reduce errors, and simplify the process of creating offline cases based on real-time data

Typically, a single customer would not encounter all of these use cases simultaneously. That is why PSS®ODMS can be priced and deployed in different configurations – so you can get only the functionality that matches your use cases. PSS®ODMS is very modular, allowing the addition of functionality over time.

Improve efficiency and ensure reliability

With its flexibility, lightweight deployment, ease of use, CIM (IEC 61970) compatibility, open architecture, public APIs, and seamless integration with planning tools like PSS®E, PSS®ODMS can benefit power companies of various sizes and functions, including TSOs, ISOs, RTOs, balancing authorities, reliability coordinators, and integrated utilities.


Benefits include:

  • Greater efficiency in your model exchange workflows / business processes
  • Higher degree of accuracy in your power system studies, models, and simulations
  • Increased power system reliability/security
  • Fewer regulatory violations/fines
  • Turnkey compliance with key regulatory requirements around model accuracy, audit trails, network analysis, and model exchange, and network model / data formats

Doubling down on America’s largest transmission system

Make no doubt, the future is electric. And it has this utility seeing double. American Electric Power (AEP) will soon have a digital twin of the largest transmission system in the U.S. The advantages? Centralized data, enhanced asset management and simplified grid planning – plus the ability to see into the future of their customers’ needs.

PSS®ODMS releases

What’s new in PSS®ODMS?

Take a look at the latest product developments and news.

Network Model Management

Reimplemented CIMdbNET APIs to support multi-threading

The reimplemented CIMdbNET APIs now support multi-threading, enabling the program to improve processing efficiency. No longer dependent on COM APIs, this was a foundational step towards improving automation and introducing web APIs in future releases.   


Quickly import & link customer profiles to one or more Modeling Authority Sets

The import functionality has been moved to a top-level location in CIMedit to make it more convenient to import user defined profiles (associate customer profiles). Once the profile is imported, users can now link it to one or more of the related ModelingAuthoritySets (MAS) at the same time. Users then can export the related profile directly from the selected MAS.  


Support for Python 3.7 for all Python APIs

PSS®ODMS now supports Python v3.7 for all Python APIs as Python 2.7 will reach it’s end of life at the end of this calendar year.

Unlimited model size configuration for 64-bit version

With the latest x64 version of PSS®ODMS, users can freely increase the model size configuration for network analysis, which was capped to 50,000-bus configuration in prior releases (note: usable program memory is limited by the available space in the machine RAM). The 50,000-bus configuration cap is still applied for x86 version of PSS®ODMS.


Editable AC/DC control settings for VS converter
It is now possible to change the VS converter control settings in a study case. This functionality is also provided via the pssoPy API. This allows customized scripting of HVDC control modes.


The control mode of the VS converter can now be conveniently changed in the network sheet – enabling users to apply a different control mode for the network analysis and network changes in one case. This functionality is also available via the Python APIs, which allows customized scripting for any VSC-HVDC control modes.


Enhancement of state estimator (SE) logic to consider transformer winding angles

State estimator now considers transformer winding connection angles (e.g., 30 degree for Y-Δ). This improves the accuracy of state estimation and post-SE power flow results when flows on the Load Tap Changer (LTC) transformers with angle shift are measured.


Network Model Management

Attach documents directly to elements (SQL Server database only)
Users can now attached documents directly to network elements. This feature allows you to link and store datasheets, pictures, reports, and more directly in PSS®ODMS. 


Ability to export the network summary
Network summaries can now be exported as a CSV file from CIMEdit. Using the CSV file, the network summary can now be easily incorporated into reports or to compare model summaries. 


Export CIM/XML reports without PTI extensions 
Users now have the option to export CIM/XML without the PTI extension data. This allows various tools, which can not handle PTI user extensions as part of XML, to still consume the exported XML.


New OPC Unified Architecture (UA) Client
The new OPCsync supports OPC UA (Unified Architecture) protocol in addition to the legacy protocols (OPC DA and OPC HDA). OPC UA leverages configurable ports which enables the protocol to be more firewall friendly and the server can be run on Windows OS and Linux as it is platform independent. Finally, the new OPCsync allows the subscription to multiple set points as well as resolving deadlock.


Contingency Analysis supports multiple voltage limit sets
Similar to flow violations, Contingency Analysis can now support multiple limit sets (normal and emergency). This gives you more flexibility to choose the different limit sets you use for Contingency Analysis.
