Dear all, I'm working on network reduction problem, in which I moved loads,all renewable generation and conventional power plants from 110 KV buses to respective connected branches (220 KV or 380 KV). I have modeled network such that distribution of load or generation will be 50 % if more than one branches are connected to 110 KV bus. And after I made branch status 0 of the branches which are connected to 110 KV buses. When I checked for islands (case_info) in my file I found 2 islands and 336 isolated buses. Also I verified it by [group, isolated]=find_island ('myfile'). My question is how to get a full system? I found three buses where generation and load does exist and are completely isolated and two islands. Also I tried to get full system by putting dummy branches to connect isolated buses and a small island but i'm not sure how to select branch parameters so that problem will be feasible.
Thanks and regards Mirish Thakur
