Improvements in AEP Calculations Using IEC 61400

{access view=!registered}Only logged in users can view the full text of the article.{/access}{access view=registered}There are no international guidelines for calculating the Annual Energy Production (AEP) of proposed wind farm projects. AEP calculations are normally based on the Measure, Correlate and Predict (MCP) methodology. The correlation has historically meant assuming a straight-line relationship between site data and long-term met station data. Such correlation methodology (including the matrix methodology) is based on simple mathematical statistics; it does not include nor describe physical properties of wind and this affects the accuracy of AEP results.
