Abstract

An advanced co-generation system (ACGS) was built at Waseda university. The ACGS consists of a gas turbine system, a steam turbine system, an ammonia absorption refrigerator system, an ammonia-water mixture turbine system and an ice storage system. The energy taken out from each turbine system is used for power generation. On the other hand, the ammonia absorption refrigerator is used for the air-conditioning during the daytime in parallel with storing heat in the ice storage system in order to meet cooling demand during the nighttime. In this paper, it is discussed that the operational planning of the bottoming stage of ACGS maximizing its electric power. And the relationship between the component capacity and the operational planning is also discussed by studying an optimal solution of the dual problem, the so called "shadow price".
