The complexity of operating a CHP plant is so great that its operators select good but not optimal operating parameters. We show that an increase of about 1-2% in profitability is possible by using mathematical optimization to compute the optimal set point values as a reaction to changing conditions. The changes affect only the operation of the plant and no physical changes or capital expenditure is required.
This has been practically demonstrated in several plants in Europe, including CHP plants which provide energy for district heating; those which supply steam to industrial plants and to all-electric power plants.
