This paper presents an algorithm to dispatch the electric load of a plant among its power feeder (tie-line) and in-plant generators such that the best economical mix of purchased and generated power is achieved. The developed algorithm is applicable to a wide class of mix generation plants, among which is the typical paper mill considered in this study. A model for the tie-line is developed based on the terms of the power purchase contract between the plant and the utility company. The tie-line power is permitted to change with load to take full advantage of the reserved capacity by the external power supply (the utility company). Several steam generators with different characteristics were synchronized in operation with the tie-line and the developed algorithm is evaluated against the conventional ways of operating the paper mill under study. The developed algorithm is also applicable to plant planning problems. An economic evaluation of new power generators addition to the system, or changes in the power purchase contract, may be obtained based on predicted load curves and estimated costs of operation.
