Abstract

The optimal operational planning model is extended to the cogeneration system including the Cheng cycle gas turbine power generation unit, which has high flexibility to change the ratio between the heat and power outputs. By adopting the mixed-integer linear programing method, it is ascertained that the operational policy of the total system can be determined intelligently. Through a case study on a district heating and cooling system, the economical aspects of the Cheng cycle cogeneration system are compared with those of the gas turbine-waste heat boiler cogeneration or the conventional energy supply systems, and the advantage of the former system is recognized as compared with the latter systems.
