储热技术在综合能源系统中的应用价值
|
摘要
能源种类的多样性、可再生能源的不稳定性、能源转化设备固有的耦合性、能源需求的复杂性等因素的叠加导致了综合能源系统突出的供需不平衡性,储热技术具有调节作用,是缓解这些矛盾的有效手段。分析了储热技术在冷热电三联供、热电联产以及电采暖等典型综合能源系统的应用价值,首次提出了在蒸汽负荷周期性大幅度波动的啤酒厂三联供系统中使用蓄热系统的优化设计方法,为平抑负荷波动,降低项目投资提供了有效途径。同时结合案例提供了典型的蓄热系统设计方法,并评价了运行效果,为综合能源系统的合理设计和协调运行提供了思路和方法。
The diversity of energy types,the instability of renewable energy, the inherent coupling of energy conversion equipment,the complexity of energy demand and other factors lead to the outstanding imbalance between supply and demand of integrated energy system.The heat storage technology is an effective means to alleviate these contradictions since it has the capacity of regularization.This paper analyses the application value of heat storage technology in typical integrated energy systems such as CCHP,CHP and electric heating.For the first time,using heat storage system as an optimal design method in Brewery CCHP system that has large periodic fluctuation in steam load is proposed,which provides an effective approach for reducing fluctuation and thus project investment.Combined with cases,it also provides a typical design method of heat storage system and evaluates the operation effect,which provides ideas and methods for the rational design and coordinated operation of integrated energy system.
