The issue is that you are defining your case in the version 1 format for MATPOWER case files, but you are adding columns (ANGMIN and ANGMAX) that are only available in the version 2 format, so they are not being read, but are being set to the default (unconstrained) values.
Simply convert your case file to version 2 format and it should work. -- Ray Zimmerman Senior Research Associate 419A Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Apr 23, 2013, at 12:55 PM, Cédric Josz <[email protected]> wrote: > Ray, thank you for getting back to me so quickly. > You shouldn't have to do anything besides specify the angle limits.
