【摘要】:提高光伏陣列的短期功率預(yù)測的精度,對光伏電站運營管理效率具有重要作用。文章提出了一種提升小波變換與BP神經(jīng)網(wǎng)絡(luò)相結(jié)合的直流側(cè)功率輸出預(yù)測滑移算法,對光伏陣列的超短期功率進(jìn)行預(yù)測。實驗結(jié)果表明,文章所提出的算法對超短期功率預(yù)測具有較高的精度,適用于晴天、多云、陰雨等復(fù)雜天氣條件。
[Abstract]:Improving the accuracy of short-term power prediction of photovoltaic array plays an important role in the operation and management efficiency of photovoltaic power station. In this paper, a DC side power output prediction slip algorithm based on lifting wavelet transform and BP neural network is proposed to predict the ultra-short-term power of photovoltaic arrays. The experimental results show that the algorithm proposed in this paper has high accuracy for ultra-short-term power prediction and is suitable for sunny days, cloudy, rainy and other complex weather conditions.
