PSS®MOD – project modeling and data management for PSS®E
A better way for PSS®E users to manage and exchange model data across multiple time horizons and stakeholders
By revolutionizing the traditional approach to maintaining transmission network models, PSS®MOD's secure, web-based application and central data repository allow multiple users to submit, view, validate and audit planning model data including time-bound network changes organized as multiphase projects.
Submit, review, validate, and exchange data with easePSS®MOD is used by Independent System Operators (ISOs), Regional Transmission Operators (RTOs), Planning Authorities with remote members, and transmission companies with local users. PSS®MOD allows you to coordinate the submission of network model data from local and/or remote users and provides access to complete study cases “on demand” for any point in time.
PSS®MOD standard features
- Organize and reorganize study cases without the need to generate a multitude of PSS®E "base cases”
- Storage of a single master network model
- Accommodation of seasonal and annual profile data sets
- Treat projects as sets of data changes that are applied serially in any order specified by the user
- Export of a PSS®E file considering equipment commission/decommission dates and out-of-service and in-service dates
- Provision of an unlimited number of ratings to be applied as Rate A, B and C in an exported PSS®E case
Enhance your PSS®MOD base package with optional add-on modules
Short Circuit Data Manager
PSS®MOD gives you the ability to manage PSS®E Short Circuit Data (i.e. SEQ Files). Sequence Files can be imported into PSS®MOD Administrator and associated with the base case (via the bus number) or a specific project. PSS®MOD takes care to construct and export the correct Sequence File associated with the exported PSS®E case during the Case Build function.
Streamline model management processes and increase productivity
Benefits of using PSS®MOD
Without the proper tools, the process of model exchange, assembly, and validation is very complex, error prone, and labor intensive. Homegrown solutions are a burden to maintain, and run the risk of becoming obsolete or unsupported. PSS®MOD provides the basis for transmission planning entities and planning engineers to automate and facilitate model management, benefits include:
- Reduction of data maintenance costs, modeling errors, and inconsistencies
- Increased productivity by minimizing time spent on model maintenance, building cases, and performing studies
- Elimination of duplicate data management efforts
- Application lifecycle cost savings derived by migrating from a custom internal application to a fully supported, industry standard product maintained by a major vendor – also hedging against an aging workforce
- North America: supports NERC-MOD-32 compliance

Full support for PSS®E v35 - Leverage all the new improvements in the newest version! PSS®E v35 introduced several big improvements which can now be leveraged in PSS®MOD 11.0, such as having multiple switch shunts on one bus. Customers can now confidently shift to the latest version of PSS®E with the full support of their centralized user management software. For consistency, MOD Filebuilder will also fully support PSS®E v35 and users can create project files for latest PSS®E version.
Configure Profile attributes according to your specific needs - In order to make the tool more configurable, the profiles used in a PSS®MOD instance need to be changeable according to the customer requirements. A user can now configure PSS®MOD according to their needs with the new option to specify all required attributes for a profile. The configuration is stored in the database and is exchanged with MOD Filebuilder via the configuration file.
Experience improved usability with simplified slider file management - Optimized usability is one of the key “must haves” for a successful network model management software. To achieve the goal to be a one-stop-shop for all PSS®E model users, all necessary files must be housed within the network model management database. Experience the improved usability of the workflows with the new capabilities to store sld-files in the PSS®MOD database and even submit sld-files with each project. Those submittals can be automatically included in a case definition, so that PSS®MOD end users can download a full package, including those diagrams.
Consume multiple MOD config files - This new features improves efficiency especially for MOD Filebuilder users who are required to submit data to various network model management (PSS®MOD) environments, for example, their own and an ISO model management system. To improve the user experience, MOD Filebuilder is now able to consume and use multiple MODconfig-files – users are then able to easily select which one to utilize. With this capability the creation of a project to submit to different model management system has become even easier and more user friendly.
Streamlined distribution of the latest version through PSS®MODweb -
The distribution and consistent use of the recommended MOD Filebuilder version amongst users has always been a challenge. All users who submit projects should be using the same version to make submission tracking and error tracking easier. With PSS®MOD 11, MOD Filebuilder can now be downloaded directly from PSS®MODweb. With this functionality every user can download the recommended MOD Filebuilder version directly after logging into PSS®MOD.
A few more notable improvements
- Validation of data constraints before storing to database
- Upload of one raw-file to multiple base profiles
- Use of MOD config for profile attributes
- Support for Python 3
- Validation of rating names
- Improvements for sequence data download along with the powerflow data
- Improved DYR parser for dynamic data
- Improved the speed for the dynamic pages for large dyr-files
- Re-enabled the feature to download the case with “Long Names” (not PSS®E compatible)
AHA! You asked - we listened.
Thank you for submitting your input for product development to the Aha! Ideas Portal. The latest release introduces enhancements influenced directly by customer ideas:
- MOD-I-67: Ability to import/export case definition
- MOD-I-63: MOD Profile active columns
Features and Enhancements released with PSS®MOD 10.3
Ability to lock data submittal by User Role - Start using the new options for locking data submittal and editing. Administrators now have the option to temporarily disable data submission and editing by user role. This will allow a more reliable case build as no additional data or status changes will be seen during that process.
Added Administrative User roles - A new privilege added to user roles allows a “super user” the ability to submit changes for data outside their group. This is intended to assist administrators in making changes to submissions on behalf of users when they are unable to make changes to their data. Any changes will be logged, and notifications will be sent to users when the data is edited. All data must then go through the standard review process.
Improved case build time with parallel processing - The case build time for multiple cases has been improved by parallelizing the work (e.g., for 20 cases an improvement around 33% can be achieved).
PSS®MOD Filebuilder redesign to make it easier to install - Filebuilder communication with PSS®E to support PSS®E dependent features has been updated to avoid the usage of the RPC interface. This will allow an easier installation as you no longer need a port release from the IT department. Now PSS®E as a service runs in the background in embedded mode and communicates with PSS®MOD Filebuilder in foreground for PSS®E related activities. A considerable improvement in performance has been observed for the same.
Project/Phase Additional Data can be populated from PSS®MOD Filebuilder - Synchronize additional Project and Phase information defined in PSS®MOD with Filebuilder. This can be done by downloading “MODConfig.xml” from PSS®MOD and placing it in Filebuilder installed directory. This additional information can be populated in Filebuilder and can be opted to be part of “user defined fields” for project and phase headers.
The PSS®MOD 10.3 is now available for download!
Release notes and download instructions were sent upon release to customers who are current in Maintenance and Support.
