Dear Dr zimmerman The Reference that I am referring to is the following, so, you mean that overload in base-case is impossible. yes?

The case14.m file included in MATPOWER (and converted from the IEEE CDF file at http://www.ee.washington.edu/research/pstca/) does not include thermal limits, so I'm not sure what violation you are referring to. On the other hand, I don't know the original source of that data, and the specified dispatch does seem a bit unusual, so I wouldn't assume it represents a normal operating condition. -- Ray Zimmerman Senior Research Associate 419A Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Mar 5, 2013, at 9:59 AM, ahmad rezaee <[email protected]> wrote: Dear all > >When I do power flow in IEEE 14 bus test system for base-case, some lines are overloaded, indeed thermal limit is violated.
