摘要
提出一种基于实时辐射采集技术的晴空工况光伏超短期功率预报方法。该方法预报时效为未来0～4h,预测点时间分辨率为15 min,每15 min滚动循环预测。以此预报方法为基础,建立了国家能源太阳能发电研发(实验)中心屋顶光伏电站的功率预测系统。现场预测结果表明,该方法具有较好的预报效果,能够满足工程应用要求。
A method of ultrashort-term photovoltaic power prediction under clear sky based on real- time acquisition technology of solar radiation was proposed, which had a prediction aging of the next 4 hours,time resolution of prediction point was 15-minute,and prediction rolling cycle of 15-minutes. Based on this method, the photovohaic generation power prediction system for the rooftop photovohaic generation plant was established in NESC. The results indicated that this method has good prediction,effect and could satisfied the requirements of engineering applications.
