In my simulation I need to discharge a battery by introducing a variable resistor in matlab Simulink, the values of this resistor are declared by: ‘’ from workspace’’ bloc. I tested the variable resistor from Simscape, but we can not connect it with a block from workspace. Thanks for helping.

this is my model. On the one hand, the PV allows to charge the battery, on the other hand, I want to introduce a profile of the real load which allows to distcharge the battery.

Use the following component: https://in.mathworks.com/help/physmod/simscape/ref/variableresistor.html

we can not connect this component with 'from workspace' bloc. The idea is to vary the resistance according to a real load variation that I have in excel format. The load which I have is a ventilator, the speed varies according to a feedback.

Hi, could please tell me how can I make the connection between the real load and the variable resistors? what is the best way to implement this?
Many thanks.
