摘要/Abstract

摘要： 为了深入研究区域综合能源系统(regional integrated energy system, RIES)中电、热以及天然气3种能量流的耦合情况,提出了一种考虑冬夏两季负荷差异性的通用能量枢纽模型,建立了该模型下的耦合矩阵,结合天然气管网与配电网稳态计算方法,制定了不同运行模式以抑制配电网电压、天然气管网气压的波动。在MATLAB/simulink平台进行仿真验证,结果表明：所提模型及计算方法可用于不同耦合程度的能流和系统稳态分析。另外,考虑季节差异性的能量枢纽运行模式能有效抑制配网电压和天然气管网气压的波动,并能提高能源综合利用效率。

Abstract: In order to study the coupling of electricity, heat and natural gas in the integrated regional comprehensive energy system, proposes a general energy hub model considering the load difference between winter and summer is proposed. The establishes the coupling matrix under the model is established, combined with, and combines the steady-state calculation method of natural gas network and distribution network, and develops different operation modes are developed to restrain the fluctuation of distribution network voltage and natural gas network pressure. The simulation is carried out on MATLAB/Simulink platform. The results show that the proposed model and calculation method can be applied to the analysis of energy flow and system steady state with different coupling degrees. In addition, considering the seasonal difference. The operation mode of energy hub that considers the seasonal difference can effectively restrain the fluctuation of distribution network voltage and natural gas network pressure and improve the energy utilization efficiency.

Key words: regional integrated community energy system, energy hub, winter and summer operation mode, newton loop-node method, multi-energy flow coupling algorithm, energy distribution plan
