Provided is a method of determining a power curve, which specifies a correlation between wind speed and a power output of a first turbine. Wind speed is calculated based on a measurement correlation, specifies a correlation between the rotor behavior and the wind speed, derived from rotor ...
In the field of wind power generation, the power curve of wind turbine is an important basis for the design of control system in the design process, and it is also an important indicator for assessing the performance of wind turbine and evaluating the power generation capacity of wind turbine...
The purpose of this work is to calculate the wind turbine power curve by using fast Gaussian Processes (GP) regression [19] for the filter step and ANN for the final modelling on the filtered data. We show that the use of GP filtering improves the power curve calculation no matter the ...
A data-based estimation of the wind-power curve in wind turbines may be a challenging task due to the presence of anomalous data, possibly due to wrong sensor reads, operation halts, malfunctions or other. In this study, the authors describe a data-based procedure to build a robust and ac...
Wind turbine power curve portrays the relationship between the wind speed and output power of the turbine. Wind speed values ranging between cut-in speed and cut-out speed acquire the most vital role for estimating wind power curve models. All wind turbines have different cut-in and cut-out ...
It is a common practice to use wind speeds at hub height in determining wind turbine power curves. Although the possible influence of other variables (such as turbulence and wind shear) is generally neglected in power curve measurements, we discovered the importance of other variables in an analy...
With the rapid development of wind power industry recently, huge data source are accumulated by the widespread supervisory control and data acquisition systems. The data-driven wind turbine power curve plays an important role in many fields, whereas it is sensitive to data quality. The invalid and...
A wind turbine manufacturer can help you estimate the energy production you can expect. They will use a calculation based on the particular wind turbine power curve, the average annual wind speed at your site, the height of the tower that you plan to use, and the frequency distribution of ...
Wind power generationis a non-linear and non-stable process. It could be modeled as astochastic process. Bothwind speedand wind-to-power curve exhibit high degree of variability, which become two main sources of uncertainty in wind power forecasts. Forecasting information is widely used as input...
