Version 1.7

Electrification Library 1.7 is part of Modelon’s 2022.1 release. New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers.

New Features

Power distribution applications

  • New application example: MicroGrid
  • New inverter experiments: GridFeeding and GridForming

Inverters

  • Added a Power and Voltage controllers (three phase AC).
  • Example inverters for grid applications: ThreePhaseGridFeeding and ThreePhaseGridForming
  • Sign change in AC current sensor signals (for consistency). Note: Any dependence on these signals need to be manually updated!
  • Added support for initializing the current control actuation.
  • Simulation state events for control limits are now disabled by default.
  • Improved robustness to grounding for AC domain.

Batteries

  • More consistent variable names in summary records (an optional record is available with the old names).
  • Removed core variables from pack summary record (use summary record of core model instead).
  • Added min/max cell variables to the pack record (an optional record can be selcted that includes all individual cells).
  • An improved BatteryCycler load, with support for both power and current control.
  • Introduced templates for diagram and code based OCV models, and migrated the Table based OCV model to a diagram implementation.
  • The example Stochastic core battery has been migrated to the new (simpler) function based approach of stochastic parameters.

Machines

  • The MultiMode machine controller now only looks for external reference signals related to the selected mode.

Loads

  • Added support for Current controlled loads (in addition to the Power controlled ones).

Converters

  • Added a Power controller for DCDC converters, and a new power mode to the MultiMode controller.
  • Added the ControlModes experiment examples for DCDC converters.

Routing

  • Introduced switches for AC and DC connections: DCSwitchResistive and ACSwitchResistive
  • Added interfaces and examples for AC routing components (e.g. cables).
  • Introduced common interfaces (Electrical and BaseComponent) for single and dual plug components (to allow e.g. replacing an ideal cable with a switch).

3D MultiBody

  • It is now possible to disable the mass and inertia properties for MultiBody3D enabled battery packs and machines, using the enable_mass_properties flag. Note that this still maintains the reaction torques in the Rotational3D flange.

Other

  • Various minor improvements to documentation and icons.
  • Improved naming consistency for controllers.
