This auxiliary interface model enables modelers to divide physical models with electric circuits at DC level into several parts and to freely cut individual electric branches. It often works in combination with the DefineDC model.

The ExtractDC covers the following applications:

  • Basic: During debugging, test simulations should show if parts of an electric circuit work properly, e.g. battery storage system with connected DCGrid but without a suitable power supplier. It therefore provides to add generic input data without closed-loop dependencies to other model components.

  • Advanced: Users want to integrate measured voltages and currents in an electric circuit as input data sets to a complex model - Hybrid Digital Twin. It provides an output interface for result evaluation and separated feedback loops.

To use this model, it is not necessary to connect any further model components to the real outputs ▶V or ▶I. However, it is still possible for debugging or evaluation purposes or as additional inputs of controls.
