摘要/Abstract

摘要：

在园区综合能源系统(park integrated energy system,PIES)的低碳经济调度研究中,从外网购电所带来的碳排放量难以准确估计,给PIES低碳经济调度的准确性带来了严峻的挑战。因此,文章利用外网电能的碳流密度对其隐含碳排放进行精确核算,并建立了PIES低碳经济调度双层优化模型,最后在一个典型PIES中进行了算例分析。结果表明:相比于单一的PIES经济调度,所提优化模型可以在只提高4.82%运行成本的前提下,降低PIES约21.37%的碳排放量。同时,通过所提模型可以对PIES的碳流分布进行优化,消除系统的碳薄弱环节,提高PIES的环保性。

关键词: 园区综合能源系统, 碳排放流, 低碳经济, 双层优化

Abstract:

In the study of low-carbon economy dispatching of park integrated energy system (PIES), it is difficult to accurately estimate the carbon emissions caused by purchasing electricity from outside, which poses a severe challenge to the accuracy of PIES low-carbon economy dispatching. In this paper, the carbon flow density of the external power grid is used to accurately calculate its hidden carbon emissions, and a two-layer optimization model of PIES low-carbon economic dispatching is established. Finally, an example is analyzed in a typical PIES. The results show that, compared to PIES economic scheduling alone, the proposed optimization model can reduce carbon emissions of the PIES by about 21.37% while increasing operating costs by 4.82%. At the same time, the proposed model can optimize the carbon flow distribution of PIES to eliminate the weak link of the system and greatly improve the environmental protection of PIES.

Key words: park integrated energy system, carbon flow, low-carbon economy, two-level optimization model
