应用等年值法构建了带蓄能设备的燃气冷热电联产(CCHP)系统优化数学模型。结合一实例,系统地研究了蓄能设备对CCHP系统经济性的影响。结果表明:在系统规划层面,蓄能可以优化设备的容量配置,降低初投资;在系统运行层面,蓄能可以增加发电设备的运行时长,保证设备运行的高效性,降低运行费用。
The optimization mathematical model of CCHP system with energy storage equipment is constructed by using the annual value method. Combined with an example, the impact of energy storage equipment on the economy of CCHP system was systematically studied. The results show that in the aspect of system planning, energy storage can optimize capacity allocation of equipment and reduce initial investment. In the system operation level, energy storage can increase the running time of power generation equipment, ensure the equipment operation efficiency and reduce operating costs.
