零碳园区综合能源系统的多属性研究

Research on Multi-attribution of Comprehensive Energy System in Zero Carbon Emission Park

针对多种业态的民用综合园区的能源需求,建立零碳排放的能源系统,利用储能系统协调自发电供应量和园区需求量之间的匹配。分析制冷和采暖设备在系统运行工况下的能流,建立设备的动力学模型。通过分析一次能源节约率和发电效率等指标并研究园区经储能调度后的柔性度,评估系统性能。结果表明:该系统的一次能源节约率和二氧化碳减排率分别在33.0%~100.0%和22.7%~100.0%。当补充电量全部匹配附近风能及太阳能等绿色能源发电时,园区可以达到零碳排放。

A zero carbon emission energy system was established for a civil comprehensive park with various business types,and the energy storage system was used to coordinate the matching between the self-generation supply power and the park demand power.The energy flow of the cooling and heating equipment was analyzed under the system working condition,and the dynamic model of the equipment was established.The system performance was evaluated with the analysis of indicators such as the primary energy saving ratio and the carbon dioxide emission reduction ratio,and with the research of the flexibility of the park after energy storage scheduling.Results show that the primary energy saving ratio and the carbon dioxide emission reduction ratio of the energy system change from 33.0%to 100.0%and from 22.7%to 100.0%,respectively.The goal of zero carbon emission can be achieved when the supplementary power is fully matched with the nearby green energy power such as wind energy and solar energy.
