Tree-anchored expert combination reduces photovoltaic forecast errors

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a method to reduce errors in multi-horizon photovoltaic forecasting by combining predictions from a primary tree model with complementary temporal predictors. This approach uses LightGBM as a strong standalone model, with a weighted combination of seven neural network implementations to address residual errors. The study found that a shared Mean Absolute Error (MAE) policy reduced scaled MAE by 3.21% compared to the standalone tree model on a dataset of over 56,000 windows from public PVDAQ systems. AI

IMPACT This research offers a method to improve the accuracy of renewable energy forecasting, potentially aiding grid stability and energy management.

    Reducing Multi-Horizon Photovoltaic Forecast Error through Tree-Anchored Expert Combination

    A strong direct tree model may remain the best standalone photovoltaic forecaster, yet a weighted combination can reduce its residual errors. We examine whether complementary temporal predictors can lower the tree's mean absolute error (MAE) over 15--240 minutes without weaker en…
