Operational improvements in the short-run scheduling of electric power generation can accrue considerable economic and fossil-fuel savings. This study has undertaken an evaluation of the worth and practicality of using “stochastic linear programming with recourse” as an alternative optimisation procedure to the conventional “mean-value” deterministic approach. The experiments were based upon a realistic power system model of the S.W. Region of the U.K. Central Electricity Generating Board. The results suggest that the approach is both practicable and economically worthwhile.
