Evolutionary programming approach for combined heat and power dispatch

This paper develops an Evolutionary Programming (EP) based algorithm for the combined heat and power dispatch problem for cogeneration systems. The problem is first formulated mathematically. The EP-based algorithm is then described. In the algorithm, methods for satisfying the heat and power operation ranges of the units in the cogeneration systems and the demand constraints are presented. The new algorithm is applied to a test system containing two cogeneration units. The results are presented and the performance of the new algorithm assessed.
