I am trying to add a variable load (Residential Load profile) in small microgrid system. I have the load profile data but i couldn't find a way to add it in simulink. I know about three phase dynamic load, however i am looking to add a customize load profile in simulink. Is there any way i can setup load profile in Simulink. I will really appreciate the help. Thanks.

You may use de signal builder block for that, i have a problem with implementing this because the load brake my entire discrete simulation, if anyone know about how to solve it will be really helpful.
Thanks you

I think , it depend on models it also similar to my question, my load profile including huge data , how can I insert in my simulink model to assess the impact?

Hi @Sina Ibne Ahmed,
You can add a variable load (residential load profile) using a "1-D Lookup Table" block to represent the load variations over time.
This block allows you to model load variations over time by mapping your pre-defined load profile data, accurately simulating real-world residential consumption patterns.
You can refer to this microgrid example, where the "1-D Lookup Table" block is used to input a time-based residential load profile.
