Improvements

Power electronics

Several additions and improvements for modeling of power electronics in three-phase AC systems. This especially focuses on using the efficient DQ0-representation (Park/Clarke-transformed) for the three-phase AC models and connections. This enables much faster simulations and experiment scenarios that are several hours long.

  • A more efficient inverter model (Inverters.Core.AverageDQ0) that describes ideal waveforms with a DQ0 representation. More information in Inverters.Information.
  • The comparisons between different inverter model fidelities now include the new efficient DQ0-model (found in Inverters.Experiments and Machines.Experiments.Fidelities.).
  • Many examples with three-phase AC have been migrated to use a more efficient representation (Park/Clarke-transformeed DQ0), including: MicroGrid, GridFeeding, and GridForming.
  • The inverter controllers have been updated to also work with the new DQ0 inverter. This includes a re-worked switchControl sub-component.
  • Inverter switching losses are now defined for a nominal RMS phase current (instead of the average phase current magnitude).
  • Introduced rectifiers in the "inverter" package (Inverters.Examples.Rectifier and Inverters.Examples.RectifierDQ0).
  • Added an example that demonstrates one of the new rectifier models: Inverters.Experiments.Rectifier.
  • Added an ideal three-phase transformer model (Electrical.ACTransformerDQ0).
  • Fixes to the LC filter models for three-phase inverters. These are now consistent between the ABC and DQ0 variants.
  • Added (optional) resistance to the inductive filter for three-phase inverters and rectifiers.
  • The three-phase AC sensors now support multiple output formats (abc and dq0).
  • For customized inverter control models, the input vAbsMax is no longer used. This has been replaced by the input vDC = 2*vAbsMax.

Batteries

Several additions for easier thermal modeling of battery packs with prismatic and cylindrical cells.

  • Example experiment with a liquid cold plate, integrated with a battery pack with prismatic cells (LiquidColdPlate).
  • Simplified thermal models of prismatic and cylindrical cells (Batteries.Thermal.Cells.Prismatic / Cylindrical), that can be used both with multi-surface connectors and a single surface heat port.
  • New example thermal models of packs with prismatic and cylindrical cells (PrismaticGrid and CylindricalGrid), that better describe heat conducted between adjacent cells.
  • New package of thermal building blocks (Batteries.Thermal.Groups) to simplify modeling groups of cells (including 2D grids and hexagonal honeycomb patterns).
  • New adapters for surfaces of prismatic and cylindrical cells (Cylindrical.SelectSurface, Prismatic.Ending, Cylindrical.Ending).
  • The package CellTransfer (previous name) has been migrated to Batteries.Thermal.Groups.Lumped, and updated to match the conventions used in the other cell group models.

Asynchronous induction motors

  • Added a speed controller (V/f) for asynchronous induction motors (Inverters.Control.AsynchronousSpeed).
  • Added an example of a speed controlled asynchronous induction motors: VariableFrequencyDrive.
  • Different set of default parameters for the example inductor machine (Machines.Examples.AC.AIM).

Other

  • Improved automatic conversion from older versions.
  • Removed deprecated battery sensors (CellCapacity and SoC).
