Abstract
The aggravation of global energy crisis and environmental pollution impels people to speed up the research of energy utilization. The multi-carrier energy system (MES) can greatly improve the energy utilization efficiency, the construction of Energy Hub (EH) model is a key in MES research. The paper proposed a novel matrix modeling method for MES. Firstly, according to the types of energy flow, energy hub is divided into different energy sub hubs, and then the detailed modeling process of energy flow equation is given. An optimal scheduling model of MES is proposed to minimize the daily cost of energy. The typical summer days with energy storage devices and demand response considered respectively are taken as cases study. Simulation results show that the method is effective and feasible for MES with different structures. The comparison of different cases shows that energy storage devices and demand response can decrease the cost very well.
