Dynamics Simulation and Modeling Updates

Second generation wind models approved by WECC are now available as part of the PSS®E library

Large scale PV model approved by WECC is now available as part of the PSS®E library

Working with WECC Battery Energy Storage Task Force (BESTF). A prototype battery dynamic model, per specification laid out by the BESTF, has been developed in PSS®E and is currently undergoing testing. This model will be made part of PSS®E 33.x and 34.x as soon as the model is approved and results are verified.Worked with WECC PSS®E user to benchmark the PSS®E composite load model with results from PSLF CMPLDW model. Currently working to develop playback functionality for voltage and frequency signals in PSS®E.

Working on the WECC multi-unit plant controller that was discussed in the last WECC MVWG meeting.

Benefits:

Software-based (dongle-less) options for individual and network licenses

Online system for management of licenses

Full compatibility with the latest operating systems and platforms

Ability to provide limited-time trials of PSS®E and modules for making better purchasing decisionsSlide12

Additional 34 Improvements

Interface, Diagram and Plotter Improvements

The network data grids have been reorganized to group common spreadsheets into tabs, allowing for quick selection between spreadsheets.

Management of large sets of study files is made simple with the new Study Management System built upon the existing scenario management concept.Single-line diagrams have been optimized for performance and improved layoutSingle-line diagram properties have been reorganized, and can be saved and loaded from external files. PSS®E Plotter now supports the popular PSSPLT functions RANG, SLCT and FUNC.Geomagnetic Induced Current (GIC) Analysis Improvements

The GIC engine supports additional functions to meet and surpass regional GIC modeling requirements. Location-based field scaling and non-uniform field calculations are now available.

Additional 34 Improvements

Dual Python 2 and 3 Compatibility

PSS®E now supports the most popular Python 2 and Python 3 versions. This gives access to the latest Python and 3

rd-party libraries that take advantage of powerful new Python 3 features. Full Python 2 backwards compatibility mean that all existing scripts will continue to work as written. Improved Power Flow ModelsIndividual loads can now be designated as distributed generation loads to properly model renewable generation. Machines may now be modeled as in-feeder devices with the proper management of machine parameters. Also, transformer impedance tables have been updated to allow 99 defined points, as well as real and imaginary pairs, allowing higher-fidelity modeling of transformers.

Additional 34 Improvements

The maximum number of buses in a network has been increased from 150,000 to 200,000 buses, making highly-detailed models of even the largest grids possible.

Solution parameters are now saved in SAV, RAW and SEQ files, along with the last know solution method, allowing a saved network case to be solved exactly as intended.

The SAV, RAW and SEQ file converters have been updated to handle conversions between version 34 and many older versions, providing backwards compatibly with previous releases. PSS®E now supports spreadsheets displaying all subsystem-based results for several major data categories, replacing text-based reports. Results may be exported directly to a CSV file or directly to Excel.Now all AC lines, two-winding transformers, and three-winding transformers names can be given names to 40 characters long.

Additional functions have been added to the PSS®E Environment Manager
