Low-Carbon Economic Operation of an Integrated Energy System Containing Carbon Capture System and Hydrogen Energy

So as to upgrade the low-carbon economy and promote multi-energy complementarity of the integrated energy system, a low-carbon economic operation and scheduling model of the integrated energy system, containing hydrogen energy, power to gas, combined heat and power system and carbon capture system, is proposed. Firstly, the operation architecture of the integrated energy system is proposed, and the internal equipment is finely modeled, and the energy coupling relationship between each equipment is analyzed. Secondly, the optimal scheduling model of the integrated energy system was constructed, the operation mechanism and energy direction of each equipment were systematically analyzed, the objective function, containing the minimum aggregate operating cost of the integrated energy system, and the lowest carbon emissions, was established. Finally, the optimized output of each equipment is solved by MATLAB, in which the wind energy consumption and the light energy consumption are increased by 11.7% and 26.72%, respectively, and the overall system cost is reduced by 850081.6 yuan, which tremendously demonstrates the advantages of the optimal scheduling model.
