Abstract
In the R&D project of the New Energy and Industrial Technology Development Organization, wind farm measurement network is established in eastern part of Japan and ramp forecasting technologies using the collected data are being developed. To evaluate the ramp forecasting performance of developed technologies, we select various metrics suitable for each forecast outputs. Critical Success Index (CSI) is defined as the primary metric in the project. We conduct ramp forecasting by the existing and developed technologies over the past period and compare their ramp forecasting performance. The developed technologies show better ramp forecasting performance than the existing technologies.
