摘要：

The load matching performance between the load output of combined cooling, heating and power systems (CCHP) and user requirement is a key indicator to assess the systems; it is inherently influenced by the fluctuation load demand of users and its method of operation. In this research, five dimensionless load matching parameters are extracted to express the load matching relations. Further, a matching map is established based on the load matching parameters, which is demarcated as two zones according to the load demand of users. Meanwhile, the energy saving rate (ESR), CO2 emission reduction (CO2ER) and operation cost reduction (CostR) of the CCHP systems over the reference separate system are analyzed for the following the electric load (FEL) and following the thermal load (FTL) strategies. Additionally, an improved hybrid load-following method (FHL) is proposed based on the comparison between the FEL and FTL strategies. Finally, the boundaries of the suitable users are also summarized when ESR > 15% for different operation strategies and seasons.
