Problems solved by technology
[0003] The traditional way of wind power storage, pumped storage is a relatively mature technical solution, but its promotion is limited by specific conditions, such as a large amount of water, reasonable terrain, etc.; electrochemical storage battery is another way, but in the short term, Whether it is lead-acid batteries, nickel-metal hydride batteries, lithium-ion batteries, or all-vanadium redox flow batteries will be limited by cost and technology maturity; other energy storage methods, such as compressed air energy storage, flywheel energy storage, etc. Because the efficiency is too low and the capacity is too small, it is difficult to adapt to the challenge of large-scale use of wind power

[0126] Taking the measured data of a wind farm in a certain area of Jilin Province as an example, the cost-effectiveness of the wind-hydrogen combined power generation system is evaluated. The specific parameters are: the installed capacity of the wind farm is 48MW, the wind speed and power output of the wind farm are measured in 2012, and the peak value of wind power is reduced. Ratio f PK =20%, hydrogen density ρ H =0.08988kg / m 3 , low calorific value of hydrogen The design operation period of the system is 50 years, the benchmark rate of return is 10%, and the market price of wind power S WE =0.496 yuan / kWh, initial experience accumulation X i =78.1856, hydrogen market price Wind power forecast error percentage f ERR =0.2, the balance expenditure C required for each kilowatt-hour of wind power without wind hydrogen system installed bl =0.002, after installing the wind hydrogen system, the balance expenditure C required for each degree of wind power blX =0.002, ca...

Description
technical field [0001] The invention is a cost-benefit evaluation method for a wind-hydrogen combined power generation system, which is applied to the joint development and exploration of wind power hydrogen production, the economic evaluation of wind-hydrogen combined power generation, and the research on the large-scale development of wind power hydrogen production. Background technique [0002] The rapid and large-scale development of wind power must urgently solve two major problems: (1) the "bottleneck" problem of grid penetration, especially during the winter heating period, the phenomenon of wind curtailment is serious; (2) it is still difficult to store wind power on a large scale. As a clean secondary energy source and a new energy storage method, hydrogen is convenient for storage and transmission, and has become one of the preferred options for large-scale development and efficient utilization of wind power. Therefore, the cost-benefit evaluation of the wind-hydro...
