摘要: 随着能源互联网的快速发展,综合能源系统建模的准确性对其运行经济性、高效性至关重要。文章在已有设备模型基础上,考虑设备间拓扑连接和能量梯级利用关系,建立面向综合能源系统的多能网络模型;建立指数型目标函数的抗差估计模型,利用实际现场的运行数据实现设备参数的准确辨识,并对比分析提出的抗差方法相对于传统最小二乘估计方法的优势;进一步提出了基于网络模型的综合能源系统效率评价模型,通过抗差辨识得到的设备模型计算多种典型工况下的理论效率,并与现场实测效率对比,证明了所提方法的有效性以及抗差参数的准确性。

Abstract: With the rapid development of the Energy Internet, the accuracy of integrated energy system modeling is crucial to the economic and efficient operation of the system. On the basis of existing equipment model, considering the relationship between equipment topology and energy cascade utilization, this paper establishes a multi-energy network model for integrated energy systems. Then the robust estimation model of the exponential objective function is established, and the actual parameters of the equipment are used to accurately identify the equipment parameters. The advantages of the robust method proposed in this paper over the traditional least squares estimation method are compared and analyzed. Furthermore, the energy efficiency evaluation model of integrated energy system based on network model is proposed. The effectiveness of the proposed method and the accuracy of the robust parameters are proved by comparing the theoretical efficiency calculated by the equipment model obtained by the robust identification with the actual measured efficiency under various typical conditions.

Key words: integrated energy system, energy supply network modeling, parameter identification, exponential objective function, comprehensive energy utilization rate
