Cost optimization of a cogeneration plant

The software package for optimization of the cost of the thermal power plant operation was developed. The plant supplies hot water for district heating, process steam for industry and electric power. The mathematical model of the plant includes four steam generators, two back-pressure turbines and other equipment like heat exchangers, deaerators and pressure reduction valves. Two optimization approaches were tried. The first one used a general-purpose optimization solver that may be found in commercial packages, without satisfactory results. The second one was the self-developed solver reflecting the design philosophy of the plant. The optimization package was tested against the plant custom operation modes. For this purpose the consumption data for two month, typical for winter and summer mode of plant operation, were chosen. In both cases cost savings ranging from 0.8 % to 5.5 % have been obtained.
