Abstract

The success of wind energy projects depends on the favorable alignment between layout definition and turbine type selection. Thus, developer-manufacturer interactions should be conducted before wind farm operation to optimize the annual energy production subject to site suitability parameters. The wind sector management (WSM) strategy definition is a typical case of this interface to minimize the fatigue loads accumulated over a 20-35 year designed operating lifetime due to ambient and wake-induced turbulence. A comparative study between pre-constructive wind resource modeling methods and SCADA operational data was conducted to evaluate the impacts on annual energy production of two operating wind farms with closely-spaced turbines in Brazil's northeastern region. The results of direction curtailment losses for each pre-constructive modeling method allow a methodology validation based on the available SCADA data.
