Capacity optimization method for open-sea wind power hydrogen production system under dynamic hydrogen production efficiency characteristic

Abstract

The invention relates to a capacity optimization method for an open-sea wind power hydrogen production system under dynamic hydrogen production efficiency characteristics. The method comprises: obtaining planning parameters; establishing a time-power-efficiency dynamic hydrogen production characteristic model by considering the hydrogen production efficiency attenuation change caused by aging of the proton exchange membrane electrolytic cell due to long-time operation; establishing an open sea wind power hydrogen production system capacity optimization opportunity constraint planning-information gap decision theory model of which the lower layer takes project benefit net present value maximization as an optimization target and the upper layer takes hydrogen price maximum uncertainty as an optimization target; and solving the open-sea wind power hydrogen production system capacity optimization opportunity constraint programming-information gap decision theory model by adopting a particle swarm algorithm based on stochastic simulation. According to the method, by considering the hydrogen production efficiency attenuation change caused by aging of the proton exchange membrane electrolytic cell, the uncertainty of the open-sea wind power output, the hydrogen production equipment replacement cost and the market hydrogen selling price, the open-sea wind power hydrogen production system capacity is optimized, and the economic benefit evaluation credibility level of the open-sea wind power hydrogen production project is improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy storage, in particular to a method for optimizing the capacity of an offshore wind power hydrogen production system under the characteristics of dynamic hydrogen production efficiency. Background technique [0002] With the energy crisis and environmental pollution intensifying, people have turned their attention to the abundant offshore wind resources, using clean wind energy to generate electricity to alleviate energy demand and reduce carbon emissions. However, the lagging power grid construction speed cannot meet the rapidly expanding offshore wind power transmission. The development of hydrogen energy storage technology provides a new way for the development of offshore wind power. Hydrogen production from offshore wind power can improve the utilization rate of wind resources, but there are still problems such as poor economic benefits. The optimal configuration of the capacity of o...

Problems solved by technology

The constant hydrogen production efficiency does not match the actual production situation, and the benefits of hydrogen sales cannot be accurately evaluated; compared with the hydrogen production efficiency characteristics that are attenuated due to the aging of hydrogen production equipment, the hydrogen production efficiency that does not consider aging factors overestimates the hydrogen production output in calculations. Increased income from hydrogen sales leads to an optimistic assessment of project income, which increases the risk of investment decisions
