[Abstract]:The inherent semi-adjustable and semi-controllable characteristics of wind power have brought great trouble to wind power and its grid-connected system. How to smooth the wind power output and simultaneously reduce the abandoned wind is the technical bottleneck that restricts the large-scale development and grid connection of wind power. Using rich wind power to electrolyze water to produce hydrogen, the produced hydrogen (hydrogen energy) is stored in place in a reasonable form, and hydrogen energy is converted into electric energy through the fuel cell energy unit when there is a gap in wind power output. A coupled fuel cell wind-hydrogen energy storage system. Aiming at the economy of wind power and hydrogen energy storage energy linkage system (Hydrogen Energy Storage System,HESS), this paper establishes an economic benefit calculation model to improve the reliability of wind power grid scheduling plan by using HESS. Firstly, the mechanism of HESS to improve the reliability of wind power grid scheduling plan is analyzed, and the charging and discharging price strategy of hydrogen storage system considering wind power prediction, actual output and dispatching force to improve the reliability of wind power grid scheduling plan is proposed. The mathematical model of HESS income including direct and indirect economic income of HESS is established, and the mathematical model of HESS cost considering HESS fixed cost and variable cost is also established. In order to improve the reliability of wind power grid connection scheduling plan, the mathematical model of HESS economic benefit calculation is built. Finally, in order to improve the efficiency and accuracy of the calculation, the research results are popularized and applied value and universal applicability are enhanced. Based on VC software platform, the editor compiled HESS economic benefit calculation software (HEBCAS), which can automatically load and process wind power data and divide hydrogen storage charge and discharge range automatically. The charging and discharging power of hydrogen storage system and the economic indexes of hydrogen storage system on different time and space scales are calculated automatically. In this paper, the wind power forecasting data, wind power dispatching data and actual wind power output data are selected for a certain wind farm as the simulation verification object. This paper simulates the mathematical model of HESS to improve the reliability of scheduling plan of wind power grid connected system, and analyzes the sensitivity of economic benefit to the error of wind power dispatching and the rated power of hydrogen storage system according to the results of the simulation. The results show that the HESS economic benefit calculation model is correct. The results of the study can provide a data reference for the economic evaluation of wind power and hydrogen storage system in the early stage, and widen the effective grid connection path of wind power on a large scale.
