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 the global “energy transition” measures are gradually moving forward, at present, fossil fuels still dominate global energy consumption. Therefore, it is particularly important how to effectively integrate renewable energy with conventional energy. In this paper, the CCHP system with embedded solar air-conditioners is taken as the research object, and a finer model is built for the air-conditioner refrigeration sector. Focusing on the three indicators of operating cost, primary energy consumption and carbon dioxide emissions, we discuss the operation status of each component in solar-CCHP system separately and use AHP’s weight calculation method to optimize the three indicators according to the difference of the index’s importance aims. In the example analysis, the influence of each major equipment configuration on the overall benefit is discussed. The status of start-stop and operation of each component in the feed-in system is optimized under the real-time electricity price environment, and the ordered load of controllable load in the system is arranged.
