Hello, I am building a Simulink model where I need to add a variable resistance element whose resistance depends on some conditions. There is no variable resistor in SimPowerSystems and when I used the variable resistor in Simscape\Foundation LIbrary\Electrical\Electrical Elements it would not connect to it. Probably its because of the mismatch in SimPower and Electrical Element library I guess.
Is there way to be solve this issue or am I doing something wrong?
Thanks in advance.

Please share with me the variable load in order to learn more about how to create it, I am having problem in order to make it variable to SPS, because exist a VARIABLE RESISTOR and A POTENCIOMETER but none of them works in SPS, it only works for SIMELECTRONICS, I can read than you solve it Chida.

Hello, I have the same problem. I saw the Sebastian's answer. but I'm not good at working with Simulink. I would be grateful if you share the variable resistance file with me. thanks a lot.

You're right... However, you can make your own custom variable resistor in SimPowerSystems by measuring the voltage and applying a current.
Look at the power_VariableInductor shipping example, which shows how you could make a variable inductor. A resistor would be easier.
