|
摘要
多能互补能源集成系统的提出,有利于实现能源间的优势互补,可以满足居民生活的多种负荷需求。其中,储能作为多能互补系统的关键设备也起到重要的作用,能进一步提高集成系统的运行效率。该文在多能互补工程思想指导下,首先建立面向气电热集成负荷终端的能源互联微网型多能互补系统,将储能模式分为单储能设备、双设备联合储能和混合储能三种,然后以多能互补系统的日前调度总成本为优化目标建立优化模型,进一步分析不同模式下储能设备之间的互相影响,并讨论三种储能模式下多能互补系统的经济性。结果证明,气–电–热混合储能模式下的经济性最优,且储能出力与各类能源负荷需求有较大关系,有利于缓解三负荷调峰的压力。
The complementary energy integration system is conducive to the complementary advantages of energy, and can meet the diverse needs of residents living, in which energy storage as a key equipment also plays an important role. It can further improve the operational efficiency of integrated system. Under the guidance of multi-energy complementary projects, this paper first established the energy internet microgriding multi-energy complementary system for gas-electric-heat integrated load. In this paper, the energy storage mode was divided into single equipment energy storage, dual equipment combined energy storage and hybrid energy storage, and set the total cost of day-ahead economic dispatching as the optimization target to establish the planning model. Then, the influence of energy storage equipment in different modes was analyzed, and the economics of multi-energy complementary system under different energy storage models were discussed. The results show that the economy of mixed storage model is the best, and the energy storage's output is related to the energy load demand, which is helpful to alleviate the pressure of three load peaking.
