摘要
With the development of hydrogen enriched compressed natural gas technology, a hydrogen mixed gas turbine has become the key technical node of electricity-hydrogen enriched compressed natural gas urban integrated energy system in the future. To this end, this paper analyzes the characteristics of the hydrogen enriched compressed natural gas network and hydrogen mixed gas turbine, and establishes the coupling architecture of the hydrogen enriched compressed natural gas network and hydrogen mixed gas turbine considering multi-component blending. From the perspective of multidisciplinary information fusion, the refined modeling of carbon emission and co-combustion output characteristics of hydrogen mixed gas turbine is obtained by Arrhenius equation and system thermodynamics, respectively. The rationality of the proposed model is verified based on the reference range of an example. On this basis, the model of hydrogen mixed gas turbine is applied to the optimal scheduling. Taking the lowest total operation cost of the system as the objective function, and considering the internal operation constraints of urban distribution network, hydrogen enriched compressed natural gas network and user units, the joint optimal scheduling model of electricity-hydrogen enriched compressed natural gas urban integrated energy system is established. Taking an actual urban distribution network coupled with hydrogen enriched compressed natural gas system as an example, the results show that the transportation with hydrogen blending in natural gas network and local hydrogen storage supply could effectively improve the renewable energy consumption level of power grid, and the difference in their wind power utilization is no more than 2.12%; however, the total operation cost of the former is 4.31% less than that of the latter, which could reduce the total operation cost of the system and effectively promote the low carbon emission reduction in users. ?2023 Chin.Soc.for Elec.Eng.
