摘要：
The integrated electrical and natural gas system is a crucial part of the integrated energy system, in which the gas turbine plays a key role as a coupling component. With the decarbonization of the energy system, the technology of hydrogen mixed gas turbines emerges. he traditional researches focus mostly on the fixed hydrogen doping ratio operations while seldom consider the dynamic adjustment of the hydrogen doping ratios. The traditional researches on optimal scheduling of the integrated electrical and natural gas system are mainly based on the operational efficiency, but with little concern about the energy and the reserve clearing with hydrogen-mixed gas turbines. This paper gives an optimal scheduling method considering the dynamic hydrogen mixing ratios of the hydrogen mixed gas turbines. The elaborate model of the hydrogen mixed gas turbine is established based on the characteristic. The hydrogen production technology based on the electrolyzer provides the hydrogen source. The hydrogen and the gas storage tanks serve jointly as the system reserve. A binomial relaxation method is used to linearly transform the gas consumption flow equation. The non-convex non-linear model is converted to a mixed integer linear programming model for the solution. Finally, the effectiveness of the presented method is demonstrated under different scenarios. The “wind power-hydrogen production by electrolyzer-hydrogen mixed gas turbine” mode is explored to improve the accommodation potential of the wind power. © 2024 Power System Technology Press.
