摘要
在机组100%为全可再生能源的多能互补系统的基础上,通过部分市网供电及"隔墙售电"消纳改进其容量配置和调度优化模型并通过LINGO求解,考察市网供电和"隔墙售电"对系统经济性和碳排放参数的影响.结果表明:随着隔墙售电的电价增长,系统的运行费用及蓄电池的容量随之下降,在售电电价增至0.33元/kWh后蓄电池单元容量趋于稳定;在售电电价达到0.37元/kWh后系统不再因电价的上升而引起系统运行策略的改变;园区多能互补系统相比不参与"隔墙售电"的传统系统,系统年总费用降低25.9%,年运行成本降低37.8%,碳排放强度由76.9 kgCO2/(m2·a)降至52.3 kgCO2/(m2·a).
Abstract
Investigating this policy's impact on such systems is particularly important.In this study,the capacity allocation and dispatching optimization model based on partial grid power supply and"electricity sales in the partition wall".The impact of grid power supply and"electricity sales in the partition wall"on energy storage ratio,economic efficiency,and carbon emission parameters are examined.The results indicate that as the price of electricity sold in the partition wall increases,the system's operating cost and battery capacity decrease,with the battery unit capacity stabilizing after the price reaches 0.33 Yuan/kWh.The system's operating strategy no longer changes after the electricity price reaches 0.37 Yuan/kWh.Compared with a traditional system without"electricity sales in the partition wall,"the park multi-energy complementary system is 25.9%more cost-effective,with a 37.8%reduction in annual operating costs and a decrease in carbon emission intensity from 76.9 kgCO2/(m2·a)to 52.3 kgCO2/(m2·a)
