Two-layer Optimal Configuration for Integrated Energy System Regarding Hydrogen Storage and Demand Response
Under the dual carbon target,in order to address the power imbalance of the integrated energy system,en-hance revenue of power operators and reduce the cost of energy purchased by power system users,firstly,a two-layer framework of the integrated energy system considering hydrogen storage was designed by combining the advantages of hydrogen storage that can be used as source-load-storage and the energy conversion characteristics of electricity to heat.Secondly,according to two different time scales,a two-stage model for hydrogen storage considering load-side demand response and user group containing electric heating equipment was proposed.The upper model combined the hydrogen storage characteristics for long time scale optimal allocation,and the lower model optimized the load of the user groups using demand response and electric heating equipment to solve the short time scale integrated energy system for hydro-gen storage optimal operation.Thirdly,the KKT condition and Big-M method were used to transform the model into a single linear one.Finally,the results show that deploying hydrogen storage as well as using electric heating equipment and demand response can improve the operator's income,increase the use of new energy,reduce customer's cost and eliminate power imbalance.
