检验评估2022年CMA-WSP、CMA-MESO、NCEP-GFS这3种数值预报模式在河北省30个光伏电站的总辐射辐照度(GHI)预报效果。结果表明:CMA-WSP预报误差最低
相关系数最高
CMA-MESO次之;CMA-WSP预报系统性偏高
CMA-MESO和NCEP-GFS预报系统性偏低。CMA-MESO在偏差200 W/m2以上的大误差比例最低、CMA-WSP次之
各数值模式均有偏差在700 W/m2以上的样本。在雾、霾、沙尘天气过程中
CMA-WSP的预报效果最好
在降雨、降雪、连阴雨、强对流天气过程中
CMA-MESO的预报效果最好。对于不同位置的光伏电站
3种数值模式在不同天气过程中的预报效果有明显差异
有些电站在各数值模式对各天气过程的预报中整体误差都较小
有些电站则整体误差较大。
This study evaluates the performance of 3 numerical prediction models: CMA-WSP
CMA-MESO and NCEP-GFS
of the global horizontal irradiance (GHI) at 30 PV stations in Hebei Province in 2022. The results show that the CMA-WSP has the lowest forecasting error and the highest correlation coefficient
followed by CMA-MESO. The CMA-WSP exhibits a systematic overestimation
while both CMA-MESO and NCEP-GFS show a systematic underestimation. The CMA-MESO has the lowest large error ratio (with a deviation of over 200 W/m)
while the CMA-WSP coming second. All models show samples with deviation of more than 700 W/m. During fog
haze
and sandstorm weather processes
the CMA-WSP performs the best
while the CMA-MESO performs the best during rainfall
snowfall
continuous rainy periods
and severe convective weather processes. For PV stations at different locations
the forecasting performance of the three models varies significantly across different weather processes. For some stations
the overall forecasting errors of all numerical models are relatively small across different weather processes
while for others
the overall errors are larger.
