Simulate in Power World the class example with the OLTC transformer. Plot the relation between the pu tap setting and the load voltage. I have used the power world app. However, I could not plot the results in Matlab. So, could anyone help me out plotting the relation between the pu tap setting and the load voltage in Matlab please ?

This is the example :
 

slack 98 MW 14 Mvar 99%2 MA 0.91 tap 150.97 KV A 90% Amps 138.26 kV 90.00 MW 0 Mvar
