Study on Techno-Economic Optimal Cogeneration Share Coefficient Considering Energy Consumption Characteristics of Variable Load Conditions
The optimal cogeneration share coefficient can guide the capacity configuration of co-generation units and maximize the economic benefits of cogeneration.In this paper,a method for determining the techno-economic optimal cogeneration share coefficient considering the energy con-sumption characteristics of variable load conditions is proposed,the off-design working condition analysis model of cogeneration system is developed,and the variable load energy consumption char-acteristics of the case unit are calculated.The techno-economic cogeneration share coefficient is optimized.The results show that the optimal techno-economic heating coefficients are 0.750 and 0.702 respectively when considering and ignoring the energy consumption characteristics of variable load conditions,and the corresponding annual cost saving relative error without considering char-acteristics of variable load conditions reaches 22.0％.More accurate techno-economic benefits of cogeneration will be obtained by considering the energy consumption characteristics of variable load conditions.
