The integrated energy system is conducive to the realization of multi-energy mutual benefit and efficient use of energy.This paper focuses on a comprehensive energy system in a park that incorporates electricity,heat,cold,and hydrogen loads.The study analyzes the coupling and cascade utilization characteristics of multiple energy sources in the operation of a renewable energy hydrogen production system and hydrogen-blended gas turbine.The impact of hydrogen blending ratio on gas turbine efficiency and the thermoelectric ratio is considered.With the objective of minimizing the operational cost of the system,an optimization and dispatching model for the park's comprehensive energy system is established under a tiered carbon trading mechanism.Segmented linearization and the big M method are employed to transform a nonlinear model containing multiple 0-1 variables and continuous variables into a mixed-integer programming model.The model is then solved using the Cplex solver to achieve fast solutions.Case analysis shows that the dispatching strategy designed in this paper can effectively improve the economic performance of the park's energy system.Properly controlling the hydrogen blending ratio in gas turbine helps reduce carbon emission in the park's system.
