通过云的图像处理预测光伏发电的功率波动的基础研究山本茂弘议员、片木武议员、再植公园议员、桥本武议员（科比商船大学）、桥本武议员（静冈大学）光伏发电系统由于其对环境的清洁性，预计将被广泛使用。它们的缺点之一是天气条件造成的发电量的意外波动。本文提出通过图像处理技术对天空中的云层进行分析，预测光伏发电的功率波动。首先，通过比较两幅连续的云图像来计算云在图像中的速度，然后，通过检查图像沿着云移动方向的颜色值来预测天气状况。实验结果，提前60、90、120秒的天气预报和太阳辐射大幅度波动所需时间的估算，显示了光伏发电功率波动预测的可能性。
A Basic Study to Forecast the Power Fluctuation of the Photovoltaic Power Generation by Image Processing of Clouds Shigehiro Yamamoto, Member, Takeshi Katagi, Member, Jaeshik Park, Student Member, Takeshi Hashimoto, Member (Kobe University of Mercantile Marine), Takeshi Hashimoto, Member (Shizuoka University) Photovoltaic power generation systems are expected to be widely used because of their cleanness in the environment. One of their disadvantages is the unexpected fluctuation of generated output caused by the weather conditions. This paper proposes to forecast the power fluctuation of the photovoltaic power gen eration by analyzing clouds in the sky through the image processing technique. First, the velocity of the cloud in the image is calculated by the comparison between two sequential images of the cloud, and then, the weather conditions are forecasted by examining the color values of the image along the direction of the cloud movement. Experimental results, the weather forecast 60, 90 and 120 seconds ahead and the estimation of the time required for the solar radiation to fluctuate on a large scale, show the possibility of the forecast of the power fluctuation of the photovoltaic power generation.
