摘要
以满足冷、热、电负荷需求时能源运行成本最低为优化目标,建立了联供系统经济最优化模型。结合实际应用场合负荷需求验证了联供系统的节能性和经济性。指出联供系统最优化运行模式与电气价格比有关,当电气价格比较低时,分供系统运行更经济。分析了各性能参数对系统经济性的影响,结果表明燃气轮机发电效率、吸收式制冷机的制冷系数及烟气余热回收效率对联供系统的经济性影响较大。
Taking the minimal operation cost meeting the load demand of cooling, heating and power as optimizing function, establishes the optimizing economical model of combined cooling, heating and power system(CCHP). Explores the energy efficiency and economics of the combined system with real projects. Points out that the optimal operation mode is associated with the electric-to-gas cost ratio. When the ratio is lower, the separate system has higher energy efficiency. Analyses the effect of the seven performance parameters on the economics of the combined system. The results show that the economics is more sensitive to the electrical efficiency of gas turbine, refrigeration COP of absorption chiller and exhaust heat recovery efficiency.
