Integration and Modeling of Multi-Energy Network Based on Energy Hub

The energy conversion units and storage equipment connected to the multi-energy system are becoming diversified, uncertain factors brought by distributed wind power photovoltaic generation make flow structure more complex, which brings great difficulties modeling application of traditional hub methods. This study deeply analyzes coupling operation mechanism systems, carries out calculation analysis systems based on an hub, so as ensure safe stable regional energy. Based physical characteristics such thermal gas this article studies comprehensive model including electric-gas-thermal network proposes decomposition supply subsystem its applicable equation Newton–Raphson method. effectiveness proposed method under different modes is verified case studies. results show that constant load, running in fixing electricity (FEL) (FTL) mode has little influence voltage each node sub-network. Within constraint range, natural obtained from coupled with meet load demand. at heat not obvious.
