Abstract
The energy hub of multi-energy system integration is helpful to promote clean energy absorption, improve energy efficiency and alleviate energy crisis. In this context, firstly, based on the structure and operation mechanism of energy hubs, the operation characteristics and output constraints of energy storage and other types of energy equipment in energy hubs are comprehensively considered. Based on the characteristics of high power generation efficiency, high energy density and high waste heat utilization of solid oxide fuel cells, an energy hub model including solid oxide fuel cells, electro-gas transfer technology, energy storage equipment, energy conversion equipment and clean energy was established. The model is solved by using YALMIP/CPLEX optimization solver based on MATLAB platform. The results show that the energy hub considering solid oxide fuel cell and electro-pneumatic technology can promote clean energy absorption through rational energy dispatching and conversion, reduce system operating costs and improve energy efficiency. Compared with the traditional dispatching model, this model has a significant economic improvement.
