基于太阳能空调的冷热电联供系统多目标优化运行研究

Research on Multi-objective Optimized Operation of Combined Cooling Heating and Power System with Solar Air Conditioning

尽管全球各国"能源过渡"措施正在逐步推进,但目前化石燃料仍然在全球能源消耗中占主导地位,因此如何有效整合可再生能源和常规能源显得尤为重要。本文以嵌入太阳能空调的冷热电联供系统为研究对象,针对空调制冷环节进行了更精细化的建模。重点针对运行成本、一次能源消耗和二氧化碳排放3项指标,分别讨论太阳能-冷热电联供系统中各组件运行状况,并且采用AHP的权重计算方法根据指标重要性差异构建兼顾3项指标的优化目标。算例分析中讨论了各主要设备配置对整体效益的影响,优化实时电价环境下联供系统各组件的启停状态与运行情况,安排系统中可控负荷有序用电。

Although ＂energy transition＂ is under way world-wide, fossil fuel still accounts for dominant position of global energy consumption at present. Therefore, how to effectively integrate renewable energy and conventional energy appears to be particularly important. In this paper, the pre-cise model of the air conditioning and refrigeration sectors is built for the combined cooling heating and power system （CCHP） with solar air conditioning. The operation status of each component in CCHP system is discussed separately with respect to such three indexes as Operation cost, the consumption of fossil fuel and the emission of CO2, and the AHP based weight calculation method is used to determine optimized objective that comprehensively consider above three indexes according to the importance of different indicators. In case analysis, the impact of main equipment configuration on system performance is discussed, the operation of combined system in real-time pricing environment is optimized, and controllable loads are arranged to realize orderly utilization of electricity.
