Hydrogen production capacity optimization and configuration method for wind power absorption and wind curtailment through hydrogen production system

Abstract

The invention provides a hydrogen production capacity optimization and configuration method for wind power absorption and wind curtailment through a hydrogen production system. The method is characterized in that the structure and operation characteristics of the wind power hydrogen production system are analyzed, and accordingly the hydrogen production capacity optimization and configuration method for wind power absorption and wind curtailment through the hydrogen production system is disclosed. By analyzing and calculating the wind curtailment level of a wind power plant, a wind power wind curtailment duration curve is formed, a wind power annual wind curtailment power statistic model is built through the interval estimation method, the maximum economic benefit serves as the target, the optimal capacity configuration interval of the hydrogen production system is determined by means of the interval optimization theory, and a multi-attribute decision-making model is built so that the optimal electrolytic cell configuration scheme of the hydrogen production system is determined. According to the method, by means of the hydrogen production system with the optical capacity, wind power adsorption and wind curtailment are conducted through the hydrogen production system, and considerable social benefits are higher on the basis of realization of wind power plant benefits.

Description

technical field [0001] The invention relates to the technical field of wind power curtailment accommodation in electric power systems, and relates to a hydrogen production capacity optimization configuration method for accommodating wind power curtailment in a hydrogen production system. Background technique [0002] my country's wind power development model is based on large-scale development and centralized grid connection. While wind power is developing rapidly, due to the constraints of technical and economic factors such as power grid construction and peak-shaving operation, the problem of wind power consumption has become increasingly prominent. According to the statistics of the National Energy Administration, in 2015, the average utilization hours of wind power in China was 1728 hours, a year-on-year decrease of 172 hours. The regions mainly include Gansu (abandoned wind rate of 39%), Xinjiang (abandoned wind rate of 32%), Jilin (abandoned wind rate of 32%), and Inne...
