含多元储能的综合能源系统多目标协同优化方法研究

Multi-objective Collaborative Optimization Method of Integrated Energy System with Hybrid Energy Storage

多元储能与综合能源系统的耦合可为社会实现“碳达峰,碳中和”的目标提供一种选择。然而,含多元储能的复杂综合能源系统的配置与运行缺乏成熟的优化方法,考虑氢能汽车作为负荷所带来的影响尚不明确。以北京某社区为例,提出了一种含有储电、储热、储冷、储氢多种储能方式的综合能源系统。在此基础上,综合考虑经济性、环保性、能效三个目标,并采用NSGA—Ⅱ算法与TOPSIS法对系统配置进行优化,分析系统性能。研究结果表明:含多元储能的综合能源系统与参考系统相比,年碳减排量提升了53.23%,年总成本降低了4.43%,一次能源节约率达到了28.16%,说明了综合能源系统具有良好的节能特性与环保特性。

The coupling of hybrid energy storage and integrated energy system provides a choice for the society to achieve the goal of“Dual-Carbon Goals”(carbon peak and carbon neutrality).However,there is a lack of mature optimization methods for the configuration and operation of complex integrated energy systems with hybrid energy storage,and it is not clear to consider the influence of hydrogen vehicles as loads.Therefore,this paper takes a community in Beijing as an example,and proposes an integrated energy system with hybrid energy storage methods including power storage,heat storage,cold storage and hydrogen storage.On this basis,considering the three objectives of economy,environmental protection and energy efficiency,the NSGA-II algorithm and TOPSIS method are used to optimize the system configuration and analyze the system performance.The results show that compared with the reference system,the annual carbon emission reduction of the integrated energy system with hybrid energy storage is increased by 53.23%,the annual total cost is reduced by 4.43%,and the primary energy saving rate is 28.16%,which shows that the integrated energy system has good energy saving and environmental protection characteristics.
