Introduction:

The growth of renewable energy sources emphasizes the need for an accurate load forecast, which plays a vital role in integrating these sources into the power grid (Holttinen et al., 2011). However, conventional load forecasting models often neglect the role of air temperature variations and their impact on electricity demand. Behmiri et al., (2023) addressed this shortcoming and successfully incorporated the air temperature into mid-term electricity load forecasting models.

Literature Review:

Existing research varies in the methods followed for electricity load forecasting. Two dominant methodologies are time-series regressions, favoring its interpretable nature (Taylor, 2010), and neural networks for their unprecedented accuracy (Sapankevych, 2009). Therefore, Behmiri and colleagues (2023) combined the benefits of the two to create an augmented model.

‍

Method & Finding:

Behmiri and team (2023) utilized time-series regressions and neural networks to incorporate air temperature data into their electricity load forecasting models. The introduction of this additional variable significantly improved forecasting accuracy. They analyzed the correlation between air temperature features and the load, and accordingly created an optimal model. Successive temperature records forecast electricity consumption patterns more accurately than those based solely on historical electricity usage (Behmiri et al., 2023).

‍

Discussion:

The integration of air temperature into load forecasting aligns with the fact that electricity demand exhibits strong seasonal patterns (Hong et al., 2016). The warmth of summer triggers high consumption due to cooling devices, while winter's cold motivates high demand for heating, both of which influence the electricity load significantly (Behmiri et al., 2023).

‍

Conclusion:

The methodology presented by Behmiri et al. (2023) provides a promising approach for impactful operational and planning decision-making aspects of power systems. As renewable resources increase, predictive accuracy of such models becomes an essential tool for energy management.
