Positive Sequence Load Flow Software

Effective power system analysis often requires large-scale simulations and manipulation of large volumes of data. When performing these analyses, efficient algorithms are just as important as the engineering models in which the data is used. GE Energy has developed Concorda PSLF. The algorithms in the PSLF suite have been developed to handle large utility-scale systems of up to 80,000 buses. ​A complete set of tools allows the user to switch smoothly between data visualization, system simulation, and results analysis.

NOTE: Files in this area pertain to the GE Concorda PSLF program. These files are restricted to WECC Member organizations that have signed a Schedule A of the GE-WECC Software Agreement No. PSED 95-0027L and have paid their annual maintenance fees to GE. These files are not to be shared except under the terms of the agreement. Unauthorized download, distribution, or use is prohibited.

PSLF users! For several decades, WECC has helped provide access to GE’s PSLF software for WECC members. Upon consideration of renewal of our contract with GE (now GE Vernova), WECC and GE Vernova have determined that a more traditional, and direct, approach is warranted. Therefore, GE Vernova will be directly providing its PSLF software and related support to WECC members.

GE Vernova will be contacting current software users directly to assist you. It is our collective goal to make this shift as smooth as possible. As always, WECC staff will remain available to assist and answer any questions during the transition. To contact GE Vernova directly, please email Marieke LeMonds, Software Operations at [email protected].
