Energy, Economical, Environmental Evaluation of a CCHP-Gshp System Based on Carbon Tax and Electric Feed in Tariff

In the paper, a new CCHP system is proposed. The proposed system consists of a power generation unit (PGU), an absorption chiller, a storage tank as well as a ground source heat pump (GSHP). Then two basic load following strategies following the electric load(FEL), following the thermal load(FTL) are compared with the strategies following the hybrid load(FHL) and following maximum electric efficiency of PGU load based on primary energy consumption(PEC), operation cost and carbon dioxide emission(CDE). Finally, sensitivity analysis is performed and results are presented when electric and gas price change.
