Abstract

Low-carbon mode is an important way to face global warming and extreme climate problems, and countries around the world have invested huge amounts of money in exploring perfect low-carbon energy-saving systems, and hydrogen energy, as the cleanest energy source, has been applied in this process. This paper proposes an optimal configuration model of electric-hydrogen hybrid energy storage system considering carbon trading and wind power fluctuation smoothing. Firstly, the basic principle of carbon trading is expressed, and on the basis of which a carbon trading stepwise cost model is proposed; then, the initial wind power signal is decomposed into the power generation demand portion and the hydrogen production portion; on the carbon trading cost model and the decomposition of the wind power signal, the hybrid electric-hydrogen system is constructed. On the basis of the carbon trading cost model and wind power signal decomposition, the hybrid electric-hydrogen system is constructed, and the optimization strategy is proposed under the objectives of maximizing wind energy consumption and optimizing the economy of hydrogen energy utilization. The study shows that under the stepped carbon trading model, the maximum utilization of clean energy can be obtained by smoothing the fluctuation of wind power, and the hydrogen produced can be sold to obtain economic benefits for reducing the cost of hydrogen production equipment.
