Comparative analysis of gas turbine cogeneration systems for designated electric supply

摘要

Economic and energy-saving properties of simple-and combined-cycle gas turbine cogeneration system for use as a designated electric supply are compared. In this supply, the properties are influenced by an electricitysupply obligation. An optimization approach is adopted to efficiently evaluate the influence on the properties. Using this approach, equipment capacities and a maximum contract demand of town gas are determined to minimize the annual total cost in consideration of operational strategies for energy demand requirements and of the electricity supply obligation.
