Abstract
Power fluctuation is a problem in increasing the capacity of wind power in the grid-system. The big fluctuation makes it difficult for the system to keep supply and demand in balance. To expand the wind power, more accurate wind power forecasting and power fluctuation control are needed. The data of wind in front of the wind turbine measured by LiDAR put on the nacelle is useful to forecast wind inflow, which enables wind power forecasting and power fluctuation control. To establish the characteristic of LiDAR, 5-min. average of wind speed and direction were compared with those measured by a cup and feather anemometer. The wind speed measured by LiDAR was 1 m/s larger than that measured by cup anemometer. The wind direction of LiDAR was 15° right from the direction of feather. Also, 5-min. average power was forecasted using wind speed measured by the LiDAR. The forecasted power using 80 m ahead wind speed measured by LiDAR was consistent with measured power. The possibility of using-LiDAR forecasting was shown by the results.
