Model and economic analysis of hydrogen consumption from hydropower considering storage capacity

Abstract

Abstract Due to the characteristics of clean and efficient hydrogen energy and its wide application, hydropower hydrogen production has become one of the potential technical means to reduce the new energy abandonment rate, and its economic benefits are analyzed in this paper. After exploring the operation characteristics of hydropower plants, the paper examines the characteristics of water and energy abandonment in combination with the calculation method of hydropower plant power abandonment, mathematically models the relevant equipment of hydropower hydrogen generation and consumption mode, and establishes a hydrogen storage and consumption model considering the capacity of storage. Based on the economic index of hydropower hydrogen production, the storage capacity of the hydropower hydrogen consumption mode is configured by combining the two-layer planning algorithm. Finally, a simulation experiment is carried out to analyze the hydropower hydrogen consumption model established in the paper and explore the optimal storage settings for hydropower hydrogen consumption. The results show that the optimal energy storage capacity of the demonstration base is 1MWh kWh cost of electricity is 0.113 yuan/kWh respectively, the whole life cycle NPV is the largest, is 7.39×106 yuan, the daily profit including hydrogen sales, electricity sales, and energy sales is about 463,110,000 yuan, and the incremental daily profit is about 144,980,000 yuan. Based on this study, we aim to promote the sustainable development of the new energy economy.
