Energy Performance Assessment of Combined Heat and Power System Based on Demand-side Viewpoint
摘要
Abstract
The combined heat and power (CHP) system breaks through the efficiency oriented energy-saving mode employed by the conventional centralized power system, and forms an effect oriented mode by coupling both supply and demand sides. Based on the dynamic balance of electricity and heat between the demand and supply sides, with respect to the "electricity tracking" and "heat tracking" operational modes as well as the five running statuses with different heat-to-power ratios, this paper proposed the theoretical formula of the primary energy saving ratio for the CHP system while comparing with different reference systems. The qualitative and quantitative analyses show that the selection of the reference system is of vital importance to the evaluation of the energy performance of the CHP system. At the point with electricity and heat equilibrium, the CHP system obtains the best energy-saving benefits. However, when the system deviates from the equilibrium point, its energy performance is closely related to the running status. In addition, the type of the prime movers, seasonal conditions may also affect the overall energy performance.关键词
