.TransiEnt.Producer.Gas.Electrolyzer.Controller.OverloadController

Information

1. Purpose of model

This is a controller to control the electric power of the electrolyzer. It has to be combined with another controller to control minimum and maximum power.

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

The electrolyzer can be operated at higher electric power than nominal power. If the power rises over a defined P_el_overload, the electrolyzer will be heated up so this operation is time limited. If the maximum overload time is reached, the electrolyzer has to be operated below or at P_el_cooldown to cool down again. In

general the electrolyzer heats up at P_el>P_el_overload and cools down at P_el_cooldown>=P_el.

3. Limits of validity

This model is only valid for constant overheating and cooling down.

4. Interfaces

P_el_set: input for the set value for the electric power

P_el_ely: output for the limited electric power for the electrolyzer
