Operational tools for large RTOs: assessment and needs

The present technology for operational tools of modern energy management systems were established in the wake of the 1965 blackout. This technology has served well the industry for quite some time. However, recent trends in the industry and especially the move towards large ISOs and RTOs have generated the need for drastic rethinking of the operational tools. The recent series of system blackouts culminated with the August 2003 northeast blackout and the Italian blackout, poses serious questions on the adequacy of the operational tools. This paper raises the questions: (a) are present operational tools adequate for the proper operation of large RTOs, (b) are the models and techniques meet present day requirements?, and (c) do present day operational tools take advantage of present day available technologies?.
