Abstract

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.
