風力予測技術の開発動向と今後の取り組みの方向性について

摘要

限られた調整力の中で,変動電源の連系を拡大するには,予測技術の活用が有効である.来年度からのNEDOの取り組みは,風力発電をいかに予測可能な変動電源として評価できるかの基礎研究であり，将来はスペインのような,出力予測技術を活用した需給運用体制の構築に資するものと考えられる.%Wind generation forecasting plays an important role for the integration of wind power generation to electricity grids and the accuracy of it needs to be improved. In particular, forecasting the abrupt and large-scale fluctuations called "ramp" in the output of wind power has become an important research theme worldwide. In this study, we have investigated the technological trends in the ramp forecasting in Europe and North America. Based on this, we have examined the appropriate direction of the wind forecasting technology that would enable the expansion of the grid connection of wind power as regulated power supply in Japan.
