Variability of power generation due to the prevalence of cloud cover over solar photovoltaics(PV)power plants is a challenge faced by grid operators and independent system operators(ISOs)in the integration of solar energy into the *** forecasts generated through ground⁃based sky imaging systems are useful for short⁃term cloud motion ***,the cost of sky imaging systems currently available in industries is relatively ***,a ground⁃based camera system utilizing a simple webcam is proposed in this *** proposed method can produce predictions with high levels of *** were generated through video analysis using MATLAB for the computation of cloud motion *** image processing involved in the implementation of the proposed system is based on the detection of cloud regions in the form of a cluster of white pixels within individual frames and tracking their motion through comparison of subsequent *** study describes the techniques and processes used in the development of the proposed method,along with the evaluation of performance through analysis of the *** predictions were carried out over multiple time *** time horizons selected include 5,10,15,20,25,and 30 *** overall results computed showed promising accuracy levels above 94.60%,which makes it adequate for generating reliable forecasts.
