Adaptive fuel allocation using pseudo fuel prices

The authors outline a practical adaptive fuel allocation approach. The approach uses pseudo fuel prices as decision variables. As a result, the fuel allocation decision can be conveniently implemented in system operation by using the pseudo fuel prices to dispatch generation. A lower pseudo price usually results in higher fuel consumption and a higher pseudo price usually results in lower fuel consumption. In the proposed approach, the systematic criterion for adaptively identifying the need for reschedulings is based on the absolute change in each pseudo fuel price. Various aspects of the proposed approach are discussed, and its application to a midwestern utility system is illustrated
