WP 2 - Modeling of a variable DC-Link voltage

[MarvinMeyer]

This issue deals with the modeling of a variable DC-link voltage.

1. First example can be a PV system: Based on irradiation and temperature curves, a variable output voltage should be obtained from the physical equations, depending on the filter current.

The implementation in Matlab (Source), based on the paper (Source), serves as a reference for the model.

In the first step, a single-phase implementation is to be created, which can later also be used for the three-phase case with the use of an inverter.

2. Battery:....
3. Windturbin....
4. ?

General implementation of v_dc as function, callable in the env.step:

First ideas/brainstroming/keep in mind...:

• Compareable to the featureize function we could write a function that is called depending on the topology of the source (PV, Batt, windturbine,...).
• The topology could be labeled in the parameter dict.
  • By default labeled as "ideal" assuming infinite source -> constant v_dc
• Example "PV": parameters of the PV-plant given in the parameter dict and used when the function is applied in the env.step

[MarvinMeyer]

Current status:

• PV systems are ready, but still need to be tested
• Batteries are in progress

[MarvinMeyer]

• [ ] Model internal resistance for loss calculation

[MarvinMeyer]

Create a structure containing the individual DC link voltages. In addition, the calculation of the stresses should be delayed by one time step.
