A net-zero carbon emission day-ahead optimal scheduling method for isolated integrated energy system
In view of the carbon peaking and carbon neutralization goals,this paper proposes a net-zero carbon emis-sion day-ahead optimal scheduling method for the isolated integrated energy system based on the hydrogen-carbon coupling,to address the self-sufficiency and low-carbon energy supply of the isolated integrated energy system(IIES).First,the amount of substance and energy balance principles is applied to analyze the cycle of different kinds of energy and carbon atoms.The net-zero carbon emission operating mechanism is proposed based on hydrogen and carbon.Then,a net-zero carbon emission day-ahead optimal scheduling model for IIES is established.The daily total cost of IIES is minimized in the optimization model,and the net-zero carbon emission mechanism,operation of power system and natural gas systems are considered by constraints.The model was transformed into a mixed integer linear programming problem.Finally,a simulation is implemented by using IEEE 39-NGS20 electric-gas interconnec-tion system.The simulation results show that the proposed method achieves 100%self-sufficiency and net-zero carbon emission operation of the system,and significantly improves the economy of the day-ahead scheduling of the IIES.
