Dear Ray,
Thank you for sharing the code for finding and extracting islands in MATPOWER case data. Could you please point out a reference (paper/book) where the implemented procedure is explained? I wonder if is possible to use your approach to check whether a network is connected and it has radial topology which is important for power distribution system reconfiguration.

Please see the help in the individual files for information on how to use them. https://www.dropbox.com/s/rkcyfslf93g1atk/finding_islands.zip -- Ray Zimmerman Senior Research Associate B30 Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Sep 10, 2013, at 11:41 AM, [email protected] wrote: Dear Ray would you please send me the codes to find islands in the system? thanks Maximiliano The latest development version of MATPOWER has some utilities for finding islands and I have happy to send you the relevant functions off-list if you like. MATPOWER should handle a DC OPF with a system with islands just fine as long as each island has its own reference bus and each island has a feasible solution (e.g. sufficient generation to meet load without overloading lines). -- Ray Zimmerman Senior Research Associate B30 Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Sep 8, 2013, at 10:18 PM, Jovan Ilic <[email protected]> wrote: Does anybody know what happens if part of the system is disconnected due to programmatically disabling branches. I'd like to run DCOPF many times while possibly disconnecting some of the lines. Thanks, Jovan Ilic
