Solar Energy Forecasting Using Statistical, Machine Learning, and Deep Learning Approaches
Bibliographic record
Abstract
Solar energy is one of the vital Distributed Energy Resources (DERs) for creating a Virtual Power Plant (VPP). However, its integration into the electricity grid is challenged by its intermittent nature due to fluctuating weather conditions. Thus, Solar energy forecasting is crucial to ensure a stable and reliable power supply. This paper performs solar energy forecasting using statistical, machine learning (ML), and deep learning (DL) approaches. A comprehensive analysis of existing literature reveals a gap in comparative studies and real-world implementation considerations. In this paper, these problems are addressed by providing a system design and modeling framework that incorporates real-world challenges such as data delays, feature selection adaptability, etc. Solar power generation was forecasted 3 hours ahead and the performance of different algorithms was evaluated including investigating the underlying reasons for their effectiveness. Results indicate that machine learning models, particularly Random Forest, outperform others with the lowest RMSE and MAE, while statistical models exhibit the least accuracy. The study was concluded with recommendations for practical implementation and directions for future research.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
