How can I run a batch file when the pc is off and is not connected to any network

I am using WinSCP to connect to my ftp server. I get files from ftp server and saved them in a local folder on my pc. I have a batch script that I run manually everyday. This script synchronizes the files in the ftp server with those in my local folder, this script ensures that any changes made to the files in the ftp server are also updated in the local folder.

NB: the ftp credentials listed are for example purpose but is similar format with my actual credential:

This is my script/batch file:

WinSCP.exe /console ftp://ftpusers01:Control_10234@172.12.500.32 synchronize local "C:\Users\KulluteweE\Documents\FTP Files" /Documents/Goarge

I have generated a report in Power BI that uses data from one of the files in the local folder. The script needs to run daily so that the report has current up to date data.

The problem I have is that I cant run the script myself every day. I need to automate the script. I have tried using task scheduler but that did not work for me. The script can not run when my pc is off/ logged out and it cant ran when I am not connected to the network.

how can I run the script/batch file automatically even when my pc is off and I am not connected to the internet. Or if this is impossible what other alternatives do I have? Please feel free to share some ideas.
