摘要：

提高能源的利用效率是能源综合服务站建设的主要目标之一,为了反映能源综合服务站能源利用、转换、损耗的特征,文章首先从宏观能效、微观能效、能源经济3个方面考虑,提出了能源利用率、可再生能源利用率、EV充电站能效、数据中心能效、能源经济成本、经济发展适应性6个评估指标,建立了能源综合服务站能效评估指标体系。其次,利用加权有向图模拟能源综合服务站内部能流情况,提出系统能量流的计算方法及能效评估方法。最后,以某能源综合服务站为算例,建立能源综合服务站评估场景,利用所提方法对系统进行综合能效评估。结果表明,文章所提模型与评估方法可反映系统内能源利用情况,适用于系统能效的预评估,对能源综合服务站的规划运行具有参考意义。

Abstract:

Improving energy utilization efficiency is one of the main goals of the construction of integrated energy service stations. In order to reflect the characteristics of energy utilization, conversion and loss of integrated energy service stations, this paper firstly considers three aspects of macro-energy efficiency micro-energy efficiency and energy economy. Six evaluation indices for energy utilization, renewable energy utilization, EV charging station energy efficiency, data center energy efficiency, energy economic cost, and economic development adaptability are proposed, and an energy efficiency evaluation index system for integrated energy service stations is established. Secondly, the weighted directed graph is used to simulate the internal energy flow of the integrated energy service station, and the calculation method of the system energy flow and the energy efficiency evaluation method are proposed. Finally, this paper takes an integrated energy service station as an example, an evaluation scenario of integrated energy service station is established, and the proposed method is applied to conduct a comprehensive energy efficiency evaluation of the system. The results show that the model and evaluation method proposed in this paper can reflect the energy utilization in the system, is suitable for the pre-evaluation of system energy efficiency, and has reference significance for the planning and operation of the integrated energy service station.

Key words: energy integrated service station, index system, directed graph, energy efficiency evaluation
