DAILY GENERATION MANAGEMENT AT ELECTRICITE-DE-FRANCE - FROM PLANNING TOWARDS REAL-TIME

This paper is intended to show the actual interest the application of new optimization methods may have in order to improve the operation of power systems. With this aim, the work carried out over the last few years to optimize day-to-day operation of electricity generation is pr esented. First, we offer a critical analysis of the modeling and metho ds implemented today for daily operation. Second, we present the metho dological breakthroughs which have been achieved in the last two years . Finally, we show how these breakthroughs will be used: in a new tool for optimizing generation schedules-the APOGEE program, in on-line op timization functions for control centers.
