Abstract EN
The wind speed sequences at different spatial positions have a certain spatiotemporal coupling relationship.
It is of great significance to analyze the clustering effect of the wind farm(s) and reduce the adverse impact of large-scale wind power integration if we can grasp this relationship at multiple scales.
At present, the physical method cannot optimize the time-shifting characteristics in real time, and the research scope is concentrated on the wind farm.
The statistical method cannot quantitatively describe the temporal relationship and the speed variation among wind speed sequences at different spatial positions.
To solve the above problems, a quantification method of wind speed time-shifting characteristics based on wind process is proposed in this paper.
Two evaluation indexes, the delay time and the decay speed, are presented to quantify the time-shifting characteristics.
The effectiveness of the proposed method is verified from the perspective of the correlation between wind speed sequences.
The time-shifting characteristics of wind speed sequences under the wind farms scale and the wind turbines scale are studied, respectively.
The results show that the proposed evaluation method can effectively achieve the quantitative analysis of time-shifting and could improve the results continuously according to the actual wind conditions.
Besides, it is suitable for any spatial scale.
The calculation results can be directly applied to the wind power system to help obtain the more accurate output of the wind farm.
