Energy ratio analysis#
The energy ratio metric is defined as the energy yield of a test turbine relative to the energy yield of one or multiple reference turbines for a particular wind rose, e.g., for annual operation. See [Doekemeijer et al., 2022] and [Bay et al., 2022] for a practical example of how the energy ratios can be used in the analyses of historical SCADA data of three offshore wind farms and their comparison to an engineering wind farm model.
Examples demonstrating energy ratio usage#
Starting in FLASC v1.4, the energy ratio calculation was reconfigured around a polars back-end and new examples were put in place to demonstrate usage.
Key syntax for computing energy ratios is provided in the examples:
With the remaining examples in examples_artificial_data/03_energy_ratio providing more detail on specific use cases.
Within the set of analysis of the smarteole dataset are also exmaples of using flasc's energy ratio calculations. See for example:
