“…As shown from the analysis, the wind speeds of adjacent turbines in the same wind direction are remarkably correlated. Research results suggest that wind speed correlation based on the transmission of wind power between wind turbines can effectively enhance the accuracy of wind parameter prediction [32][33][34]. At present, the error of wind parameter prediction is usually between 25% and 40% [32].…”

“…There are two technical approaches for the typical research methods of wind parameter predictive perception: statistics [23][24][25][26][27] and the intelligent algorithm [28][29][30][31][32][33][34]. For the statistical approach, a statistical analysis of the historical data is made with all types of regression techniques and a mapping relation is established between the actual values and the predicted ones.…”

“…There are generally artificial neural network (ANN) [28][29][30][31], support vector machine (SVM) [31][32][33] and Kalman filtering method [34] approaches. In recent years, with the development of big data and data-mining technology, the use of spatial correlation between wind farms in predicting wind speed and wind direction has opened up a new route for wind parameter predictive perception [34][35][36][37][38]. The spatial correlation method selects multiple sets of historical data from wind farms at different locations [36], with all factors taken into consideration, including geographic space (wind turbine distribution and topological structure, etc.…”

The paper presents an overview of the traditional methods to obtain wind parameters such as wind speed, wind direction and air density. After analyzing wind turbines' arrangements and communication characteristics and the correlation of operation data between wind turbines, the paper proposes a novel recombination-sensing method route of "measuring-correlating-sharingpredicting-verifying" (MCSPV) and explores its feasibility. The analysis undertaken in the paper shows that the wind speed and wind direction instrument fixed on the wind turbine nacelle is simple and economical. However, it performs in-process measurement, which restricts the control optimization of wind turbines. The light detection and ranging (LIDAR) technology which is accurate and fast, ensures an early and super short-time sensing of wind speed and wind direction but it is costly. The wind parameter predictive perception method can predict wind speed and wind power at multiple time scales statistically, but it has limited significance for the control of the action of wind turbines. None of the traditional wind parameter-sensing methods have ever succeeded in air density sensing. The MCSPV recombination sensing method is feasible, both theoretically and in engineering, for realizing the efficient and accurate sensing and obtaining of such parameters as wind speed, wind direction and air density aimed at the control of wind turbines.

It is known that there exists a function interpolating a given data set such that the graph of the function is the attractor of an iterated function system, which is called a fractal interpolation function. We generalize the notion of the fractal interpolation function to the graph-directed case and prove that for a finite number of data sets there exist interpolation functions each of which interpolates a corresponding data set in R 2 such that the graphs of the interpolation functions are attractors of a graph-directed iterated function system.
