  • Added a license for PSS®E Import available to all users
  • Added a model to the Target Inputs and Outputs Library:
    • Target I/O Interface to help visualize and simplify the management of I/O connections in the schematic 
  • Added models to the Control Protection Relay Library:
  • Added new Example models:
    • Renewable Energy: MicroGrid Droop Control which demonstrates the Islanded Operation of an Inverter-based Microgrid Using a Droop Control Technique 
    • IO Interfaces: MuSE Example Project with the OP5033 which shows how MuSE can easily expand I/O capability by connecting multiple FPGA-based I/O expansion chassis
    • IO Interfaces: Added MMS Support and the IO Interface component to the IEC61850 Sync1588 Example Model
  • Added the following Python API commands:
  • Added a new Warning for devices that are missing sensors 
  • Added a "Select/Deselect All" option for Record in Sensors Summary Form 
  • Added the ability to lock a model when a second user opens the same model when more than one instance of HYPERSIM is running
  • Added a Transformer Data tab in the Z-Based Transformer Parameter form that enables users to automatically generate parameters from manufacturer specifications 
  • Added FPGA details and a refresh button to the Target Information window that returns FPGA card type and Chassis ID 


  • Improved the simulation startup time for large models
  • Improved the Sensor Management workflow 
  • Improved Simulation Settings window with a cleaner interface, and additional information such as the Target Architecture
  • Improved error messages:
    • related to RPC timeouts by giving more specific information and additional details 
    • when a user attempts to start or apply a Target when the license (Host and/or Target) is invalid or missing 
  • Improved battery current measurement from bundle to output pin which will improve stability


  • Fixed .oprec opening error when double-clicking on the file 

  • Fixed signal group returning to the default value when clicking on record in sensor summary view 

  • Fixed issue in Export Project Wizard where not all sensor configuration files were listed
