摘　　要：卡诺电池是一种成本低、不受地理条件限制的新兴储能技术。采用相变材料蓄热的卡诺电池储能密度高,应用前景广阔。本文构建了基于填充床相变蓄热器的卡诺电池系统并建立其动态模型,分析了换热流体流量与有机工质流量对系统性能的影响,建立了1000 kW设计功率下换热流体流量和有机工质流量的函数关系式。在此基础上以往返效率和储能密度为优化目标,采用NSGA-II算法进行多目标优化,基于LINMAP方法得到权衡后的往返效率和储能密度分别为62.74%和12.96 kWh/m^(3)。Carnot battery is an emerging energy storage technology characterized by low cost and independence from geographical constraints.The use of latent heat thermal energy storage in Carnot battery results in high energy density,offering broad application prospects.This paper constructs a Carnot battery system based on a packed bed latent heat storage and establishes its dynamic model.The analysis includes the impact of heat transfer fluid flow rate and organic working fluid mass flow rate on system performance.A functional relationship for the mass flow rates of the heat transfer fluid and organic working fluid has been established at a design power of 1000 kW.Subsequently,using the NSGA-II algorithm for multi-objective optimization with roundtrip efficiency and energy density as optimization objectives.After balancing using the LINMAP method,the roundtrip efficiency and energy density obtained were 62.74%and 12.96 kWh/m^(3).
