Analysis Model for Operation Strategies FTL of NG Distributed CCHP System Driven by Gas-Steam Combined Cycle in Rural Areas

Abstract

Distributed combined cooling, heating and power (CCHP) system shows great advantages and provides new development space for energy construction of rural areas in China. Economic benefits are the most important factors determining the further development of distributed CCHP system in rural area and the operation strategies make a great impact on its economic benefits. This paper establishes an analysis model for the operation strategies following the thermal loads (FTL) of NG distributed CCHP system driven by gas-steam combined cycle. The prime mover used in this investigation is a gas-steam combined cycle based on combined gas turbines and steam turbines. The model presented in this paper can be used to determine the operation strategies of CCHP system under different daily periods: peak periods, flat periods, and valley periods in different seasons.
