Dear Matpower community,
I was doing some interpretation for pattern of Lagrange multiplier
correspond to Qg limits on case5.m.
I have done some modification on the network which are as follows:
m = loadcase(case5);
m.bus(:,[3,4]) = m.bus(:,[3,4])*0.65;
m.bus(:,[4]) = m.bus(:,[4])*-2;
r = runopf
Your understanding is correct. However, with numerical algorithms such as the
primal-dual interior point method used by MATPOWER’s default OPF solver,
depending on the numerical termination criteria for the algorithm, some
non-binding constraints may still have small non-zero values for their
m
Wow, its been 2 years of using Matpower and I was unaware of this setting.
Thank you Sir.
Best regards,
Deep Kiran
