Hybrid LLM Architecture for Energy Forecasting
This research introduces a novel hybrid TimeGPT model that integrates a Graph Convolution Network (GCN), Gated Recurrent Units (GRUs), and a Transformer Decoder. This architecture is specifically designed to capture complex spatial and temporal dependencies in energy consumption data, a critical factor for accurate short- and long-term predictions.
Unlike purely foundational LLM models, this task-specific design allows for efficient training on individual resident smart-meter time series, even with limited data. By incorporating environmental factors like temperature, humidity, and weather conditions, the model enhances its ability to generalize across diverse household consumption patterns.
The Role of Each Architectural Component
The proposed model's strength lies in the synergy of its components. The Graph Convolution Network (GCN) adeptly captures spatial relationships among households, identifying how consumption patterns are interconnected. The Gated Recurrent Units (GRUs) focus on short-term temporal dependencies, processing sequential data efficiently and mitigating vanishing gradient issues.
Finally, the Transformer Decoder, with its self-attention mechanism, excels at capturing long-term dependencies and global sequence-level attention. This layered approach ensures that both local variations and broader trends in energy consumption are effectively modeled, leading to a more comprehensive and accurate forecasting system.
Superior Performance Across Various Forecast Horizons
The model was rigorously evaluated across multiple forecast horizons: 1-hour (1H), 4-hour (4H), 6-hour (6H), 12-hour (12H), and 24-hour (24H). The results consistently demonstrate that the hybrid TimeGPT model outperforms several baseline models, including TimeGPT, Chronos, Moirai, Linear Regression, LSTM, MLP, and XGBoost, achieving lower MSE, RMSE, and MAE across the board.
This consistent outperformance, especially in longer forecast horizons like 24H, highlights the model's reliability for both real-time operational adjustments and strategic long-term energy planning in smart grids.
Enhanced Generalization and Practical Deployment
A key finding is the model's strong generalization ability. Its design as a task-specific alternative, rather than a foundational pre-trained model like TimeGPT, allows for efficient training with limited data, making it highly suitable for individual resident smart-meter time series. The integration of diverse environmental factors also contributes to its robustness in varying conditions.
The model's interpretability and consistent performance across diverse consumption patterns underscore its suitability for deployment in real-world smart energy systems, where precise and stable predictions are paramount for sustainability, stability, and efficiency.

0.0026 MSE
Average MSE at 1H Horizon, demonstrating superior immediate prediction accuracy.
Real-world Performance in Diverse Residential Settings
The proposed hybrid model's consistent performance across various residential consumption patterns underscores its practical applicability. For instance, in the 1H forecast horizon, residences like R1, R5, and R6 show significantly reduced MSE values of 0.0001, 0.0023, and 0.0029, respectively, outperforming most baseline models. Even in instances where other models like Moirai and Chronos achieve localized improvements for specific residents, the hybrid model maintains a superior average error profile (MSE: 0.0026, RMSE: 0.0487, MAE: 0.0334).
This stability extends to longer horizons. For the 24H forecast, the model consistently yields the lowest average MSE (0.0041), RMSE (0.0622), and MAE (0.0386), proving its ability to accurately forecast consumption over extended periods. This resilience against increasing forecast horizons, a common challenge for many models, makes it an ideal candidate for integration into advanced smart energy systems requiring reliable, long-term predictive capabilities.
