Abstract

The estimation of possible (or available) power of a downregulated offshore wind farm is the content of the PossPOW project (See PossPOW Poster ID: 149). The main challenges of this estimation process are:
1) to determine the free stream equivalent wind speed at the turbine level since the accuracy of nacelle anemometers are in question and power curve derivation is no longer applicable during downregulation
2) to apply a real-time wake model which can calculate the power production as if the wind farm was operating normally even in short downregulation periods. However, most existing wake models have only been used to acquire long term, statistical information and verified using 10-min averaged data
The proposed methodologies to overcome those challenges are presented in this poster.
