Joint Optimal Operation of Integrated Electricity-Hydrogen-Heat Energy System Based on Concentrating Solar Power Plant and Flexible Load
In order to solve the problems of poor operation flexibility and difficulty in the wind and solar absorption of the existing integrated energy system,and at the same time,to make full use of hydrogen energy to achieve carbon emission reduction goals,a joint optimal operation method of electricity-hydrogen-heat integrated energy system based on concentrating solar power plant and flexible load is proposed.Firstly,based on the model of concentrating solar power plant and a hydrogen energy system with waste heat utilization containing electricity to hydrogen,an integrated energy system of electricity-hydrogen-heat is constructed.Secondly,based on the characteristics and adjustment value of the electricity-hydrogen-heat flexible load on the demand side,a model of electricity-hydrogen-heat flexible load with translational and transferable load reduction is constructed.Then a joint optimization operation model of electricity-hydrogen-heat integrated energy system based on the characteristics of electricity-hydrogen-heat flexible load regulation is further constructed.Finally,the simulation of the proposed method can balance economic operation and low-carbon effect,which can not only improve the joint operation capacity of concentrating solar power plant and hydrogen energy system but also effectively improve the operating economy and low carbon of the system.The peak-to-valley difference of electricity,hydrogen and heat load is reduced by 6.68％,11.95％and 8.35％,respectively.Besides,the total operating cost of the system is reduced by 24.4％.
