Operators of wind turbine parks are required to nominate their energy production the day before this production. One method to arrive at such a production estimate is by the use of Wind Power Plant Simulation (WPPS) modeling. Improving such park production models can result in improved predictions, saving the operator money, and early detection of underperforming assets, allowing the operator to address the underlying issue and increase production. The main purpose of the project is to improve the wind farm power prediction by Wind Power Plant Simulation (WPPS) modeling. The performance of the simulation model is assessed by comparison with the Supervisory Control and Data Acquisition (SCADA) data of an offshore wind farm.
