Cogeneration: A key technology for energy saving
by Koichi Ito
International Journal of Global Energy Issues (IJGEI), Vol. 5, No. 2/3/4, 1993

Abstract: As dispersed and small-scale energy supply system, cogeneration technologies are receiving much attention world-wide. Two optimal planning problems are discussed for the fundamental design of cogeneration systems; i.e. gas turbine and fuel cell systems. The capacities of gas turbine or fuel cell cogeneration units and other auxiliary machinery are determined together with maximum demands so as to minimize the annual total cost in consideration of each system's annual operational strategy. These optimization problems are solved efficiently by considering the hierarchical relationship between the sizing and the operational planning problems. The system's capacity design, economics, and energy savings are investigated in detail through numerical studies on these systems.
