so i have a solar PV model in simulink which is ( power_microgrid) attcahed below. i can change the battery number but i'm wondering how to change the pv model number like the panel numbers and such. Also how to change the load number which is the houses in this case? so how can i change it to another load.

first picture: the whole system

second picture: inside the pv model or solar panel( just before the battery and houses)

third picture: inside of the load(houses) one of them

Hi ABDALAH ADAN,

I see that you are facing difficulty in changing the load in the solar panel PV model in Simulink. To change the load, you will need to follow these general steps:

Locate all the blocks that represent the load within the model. You can adjust the number of these blocks to match the number of houses you want to simulate. You can do this by copying and pasting to add more blocks or deleting blocks to have fewer. Ensure that the electrical connections (e.g., in parallel) are correctly made to represent the collective load of all houses.
If you want to change the type of load (e.g., from residential to industrial), you may need to replace the existing load blocks with new ones that have the appropriate characteristics for the new load type.
After changing the load, you may need to adjust other parts of the model to ensure proper operation. This could include re-tuning control systems, resizing inverters, or adjusting protection settings.

For changing the number of PV panels:

Find the block that represents the PV array.
Since the array is made up of multiple blocks, you can add or remove blocks to represent more or fewer panels, respectively. Make sure to adjust the wiring and configuration to match the intended series or parallel setup.

Hope this helps!
