Optimization scheduling of integrated energy considering magnesium-based solid hydrogen storage
In order to promote the uptake of wind power,reduce energy cost and carbon emission,a integrated energy optimization scheduling method based on magnesium-based solid hydrogen storage was proposed.Firstly,for excessive wind power,the system architecture including e-lectrolytic cell and magnesium-based solid hydrogen storage device was constructed.Then,combined with the energy flow and energy coupling among hydrogen fuel cell,methane reactor,waste heat boiler,gas boiler,absorption refrigerator and other equipments,an integrated energy sys-tem considering multi-energy co-supply is established.Finally,taking the minimum operating cost of the integrated energy system and the min-imum carbon emission of the integrated energy system as the objective function,the optimization model was established considering various constraints,and the optimal solution was obtained by calling the YALMIP toolbox and CPLEX solver in MATLAB based on the entropy weight TOPSIS method.The simulation results show that the proposed optimal scheduling method can promote the complete absorption of wind power,reduce the system operating cost by 5.05％,and reduce the system carbon emission quality by 10.00％.
