Hi All. With regard to the use of load flow for radial networks, I would like to know if there is for distribution systems with several separately represented radial feeders. That is, each one With their respective sources (substations). For example, note the case 16 buses below
[cid:1d225046-6652-4dd9-a8bc-c7bd6722849e] This case can be represented in MATPOWER in two different ways, as below: A) % bus_i type ... mpc.bus = [ 1 3 ... 2 1 ... 3 1 ... 4 1 ... 5 1 ... 6 1 ... 7 1 ... 8 1 ... 9 1 ... 10 1 ... 11 1 ... 12 1 ... 13 1 ... 14 1 ...]; B) % bus_i type ... mpc.bus = [ 1 3 ... 2 3 ... 3 3 ... 4 1 ... 5 1 ... 6 1 ... 7 1 ... 8 1 ... 9 1 ... 10 1 ... 11 1 ... 12 1 ... 13 1 ... 14 1 ... 15 1 ... 16 1 ...]; When carrying out the load flow for the two cases (A and B), success was obtained for the two cases by Newton's method. However, for the PSUM, ISUM, and YSUM methods, none of them were successful. Can anyone tell me if there is the possibility of running the load flow for distribution systems Radials that use the representation of a substation for each feeder?
