This paper is based on material presented at the IEEE 1995 Winter Power Meeting Panel Session on Challenges to optimal power flow (OPF), sponsored by the IEEE working group on operating economics. The paper contains a brief summary of the session followed by summaries. The sessions covered are: an OPF user's perspective; challenges from a planning perspective; extended applications of OPF; OPF application in deregulated electricity market; challenges to on-line OPF implementation; and control applications of OPF in EMS.
