摘要:

能源互联网是未来能源供应体系的重要发展方向,冷热电三联供实现了冷/热和电能之间的联系,是能源互联网的核心部件之一。在考虑集中式冷热电三联供运行时,燃气-蒸汽联合循环机组的启停机方式和运行状态将直接影响到三联供机组的工作效率与运行收益,合理的开机策略是保障三联供机组经济化运行的前提与基础。针对以燃气-蒸汽联合循环机组为动力装置,使用吸收式溴化锂制冷技术,配有以相变材料为主体的储能设备的三联供机组进行分析,根据对三联供机组运行相关参数,在对某地区的冷热电负荷进行详细调研的基础上,建立起集中式三联供运行的经济性目标函数,给出三联供机组经济化运行的启停机策略,从而达到提升工作效率、增加运行收益的目的。

Abstract:

Energy internet is an important development direction of future energy supply systems, and combined cooling, heating and power (CCHP), which is one of the fundamental elements of energy internet, builds a conversation relationship between heating/cooling and power. When considering the operation of concentrated CCHP, the unit startup and shutdown method of gas-steam combined cycles and its operating state will impact the running efficiency and operating income of concentrated CCHP. So the reasonable unit startup strategy is the promise and foundation for the economic operation of CCHP. This paper analyzed the CCHP that used gas-steam combined cycle as power plant, lithium bromide absorption refrigeration technology and phase-change energy storage devices. According to relevant operating parameters of CCHP units, the economy objective function of concentrated CCHP operating was established based on the investigation of cooling-heating-power load in a region;and a unit startup and shutdown strategy of CCHP under economic operation was proposed, in order to improve the work efficiency and increase the operating income.

Key words: combined cooling, heating and power (CCHP), economic operation, unit startup and shutdown strategy, lithium bromide absorption refrigeration, phase-change energy storage
