I am a student working on an OPF model for a 15 bus power system. I discovered an issue whereby the converged voltage magnitude output values do not keep within the voltage constraints, which I have set to be Vmax= 1.05 and Vmin= 0.95. This happens primarily for the PF study only.
I would like to know why would there still be a converged output even if the voltage constraints are not met. Thank you in advance for any response to this query. Please refer to the following screenshots for reference.
