Hello everyone, Is there any option in MATPOWER to set the transformer tap settings, and if it is then how we can set the settings and after running power flow, how these settings are extracted from the results? Please help. On Wed, May 17, 2017 at 12:10 PM, Bone, Gorazd

Hello everyone, I am working on my project and I got stuck with reactive power loss. I was trying to calculate the reactive power loss for all the branches. I have given the following case below- I run the normal power flow for the case attached below by the following command- << runpf (case9ab)

Line loading limit

Hello everyone, I want to ask a simple concept of line loading limit, As i have asked earlier also the rate A variable is only used in MATPOWER to limit the line. Other two rates are of no use. I am trying to make a line congested by limiting its limit. here is my following case- define_constants;

regarding CPF

Thanks for solving the problem. Now my CPF is running, but there is one more problem. I have successfully run the CPF for my case30aaa and i found the the minimum bus voltage is at bus-8, and now i want to inject reactive power at this bus in order to reduce the losses, and make the status of the
