Information

1. Purpose of model

Model of a controller for the PtG plant in operation mode RE with limited hydrogen output.

2. Level of detail, physical effects considered, and physical insight

Controller considers minimum and maximum power of electrolyzer. If desired power is too low, output signal is zero.

3. Limits of validity

(no remarks)

4. Interfaces

Three inputs: mass flow from PtG plant; maximum permitted mass flow; available RE power

One output: desired electrical power of PtG plant

5. Nomenclature

(no remarks)

6. Governing Equations

(no remarks)

7. Remarks for Usage

Definiton of minimum and maximum power of PtG plant is required.

Depending on application adjustment of PID controller will be helpful.

If useMassFlowControl=true, the electrical power of the electrolyzer will no more be limited by given m_flow_feed. This simplifies the controller if limitation is not needed.

8. Validation
