• A newControl Microgrid library is available, offering multiple control blocks:

  • Active Power Dispatch

  • BESS Management

  • Curtailment Management

  • Islanding Management

  • Load Management

  • Reactive Power Dispatch

• External controllers can now be added to HYPERSIM based on the recommendations of the CIGRE B4.82 working group which allows to standardize the integration of real manufacturer code in simulation software.

• See CIGRE Interface for more details on how to add and configure a CIGRE block to a circuit.

• See The CIGRE Interface for more details on how to create a CIGRE library.

A new

example model has been added to demonstrate the CIGRE block using a Forward Euler integrator: Examples | CIGRE integrator .

A new option has been added that allows to define a number of steps to be executed without IOs at the beginning of the simulation to improve simulation performance.

• See the “Number of steps before enabling I/Os” option in the https://opal-rt.atlassian.net/wiki/spaces/DOCHS/pages/20189498/Simulation+Settings#Advanced .

• Note that before that, HYPERSIM was always executing 100 steps without IOs. This new option simply allows to change this value.

• It is now possible to get the license number and target number in the license panel of the Target Manager.

• Python API:

  • A new methodgetVersion is available to get the current HYPERSIM version

  • Multiple new simulation and task mapping settings can now be updated using the setPreference and getPreference methods. These settings are now listed in theSimulation Settings and the Task Manager | Summary and Preferences documentation.

...

• Fixed an issue where the RT Monitor table was displaying incorrect status in the “Enabled” column when scrolling the table

• Fixed the Start/stop timeout defined in HYPERSIM (Simulation Settings → Advanced → Simulation Server) that was not always correctly taken into account.

• Fixed an issue during analyse when a UCM with selected sensors was duplicated.

• Fixed an issue where the Activation Tool was not responding when applying a license from Help&Support.

• Fixed an issue where the HYPERSIM engine was crashing when analyzing the network from the Load Flow Viewer.

• Fixed an issue where the HYPERSIM engine would crash with certain parameter configuration of the 3-winding, w/sat + tap +dec block. The engine would crash when

  • the Vmin parameter was greater than the Vmax parameter, or

  • the Vnom parameter was not between Vmax and Vmin

• Fixed a HYPERSIM engine crash when a file that is not a .pun was used in line components.

• Fixed an issue that was slowing down the load flow computation in some cases.

• Fixed a bug where load flow Load Flow properties weren't being saved when the model was saved.

• Fixed an issue where the Frequency Protection block was not taking into account the initial value.

• Fixed an issue where changes to parameters in the Load Flow window were not applied, despite appearing to update visually.

• Fixed an issue where Line with Line generator did not take the frequency and the ground resistivity into consideration.

Removed

• Unused G_Ref and P_Ref sensors on Network FACTS and HVDC LCC pulse components were removed.
