Abstract
Wind energy is playing an increasingly important part for ecologically friendly power supply. The fast growing infrastructure of wind turbines can be seen as large sensor system that screens the wind energy at a high temporal and spatial resolution. The resulting databases consist of huge amounts of wind energy time series data that can be used for prediction, controlling, and planning purposes. In this work, we describe WindML, a Python-based framework for wind energy related machine learning approaches. The main objective of WindML is the continuous development of tools that address important challenges induced by the growing wind energy information infrastructures. Various examples that demonstrate typical use cases are introduced and related research questions are discussed. The different modules of WindML reach from standard machine learning algorithms to advanced techniques for handling missing data and monitoring high-dimensional time series.

Notes
- 1.
The source code is publicly available on http://www.windml.org.
- 2.
Similarly, Greaves et al. [1] define a ramp event for a wind farm as a change of energy output of more than \(\theta = 50\) of the installed capacity within a time span of four hours or less.
- 3.
We define a pattern as \(\mathbf {x}_i = (p_1(t),\ldots ,p_d(t))^T\) with turbines \(1,\ldots ,d\) at time \(t=i\).
