Wind power generation wind measurement data is a secret

How is wind power data generated?

These data are usually generated by transforming real or modeled wind and weather data into synthetic wind power data. By mapping wind intensity with a turbine-specific power curve to extracted wind power, data can be generated without taking any—potentially disclosed—wind power data of the turbines that are modeled into account.

How many wind data are collected?

After removing some abnormal and unreasonable data such as the missing data by sensor fault, measurement error data and low temporal resolution data, a total of 47,084 wind data are collected. The statistical description of wind speed, its direction and wind power data for 1.8 MW wind turbine are shown in Table 1.

How do I find datasets for wind power forecasting?

We compiled the datasets listed in this paper in several different ways: Searching online for datasets, getting in contact with wind power forecasting researchers from every continent to ask for available open-source data and energy data regulations in their region, and searching for papers that work with disclosed data.

Is 1 year of data enough to predict wind speed?

However, due to yearly seasonality, it is generally assumed that 1 year of data is not sufficient to discover trends in wind speed or wind power. Vargas et al 20 investigate 145 different models and come to the conclusion that most models for long-term forecasting use hourly data (49%).

What are wind speeds and generation based on?

The repository contains wind speeds and generation based on three different meteorological models: ERA5, MERRA2, and HRRR. Data are publicly accessible in simple csv files. Modeled generation is compared to regional and plant records, which highlights model biases and errors and how they differ by model, across regions, and across time frames.

Is the mapping from wind speed to wind power deterministic?

Scatterplot that shows wind power on the y-axis and wind speed on the axis. The plots show data from the first turbine of the dataset in Beberibe and Pedra do Sal 36 respectively. It can be seen that the mapping from wind speed to wind power is not deterministic
