probably go with the first PV bus, and if there are no PV buses, then that whole island blacks out and you can set all its buses to type NONE. Hope this helps,    Ray On Dec 4, 2021, at 12:58 PM, prem panigrahi <prempanigr...@outlook.com> wrote: Dear R

Dear Ray sir, is their any direct process to remove bus along with their branches . I am using mpc.branch method to remove a bus with its branches. But I am facing difficulties when I have to remove more than 100 buses. mpc.branch([6161;7479;7480;7488;7489;7490], BR_STATUS) = 0;

Hello Sir In IEEE 57 bus, I fixed the capacity of transmission line and then increase the load and generation. I removed those lines whose power flow is more than their capacities. When the grid is divided into 4 parts. I remove the isolated buses. In island 1--- 45 buses are there
