Abstract: In recent years, as renewable energy generation gradually replaces fossil fuels as the mainstream power generation method, the instability during the generation process poses numerous challenges for power operation. To address these challenges, this paper combines digital twin technology and deep learning models to propose a new renewable energy power forecasting method. By constructing a digital twin-based monitoring platform, rea-l time monitoring of renewable energy generation systems is achieved, and a deep learning model, ELNet (ElectricNet), is developed to predict power generation for specific future time periods. Additionally, a grid search method is employed to automatically optimize hyperparameters, effectively reducing the time cost of manual parameter tuning. Testing on four datasets demonstrates that,compared to other models,the proposed model improves performance by an average of 25.246 percentage points under the Mean Squared Error (MSE) evaluation standard, enabling more accurate power generation predictions and effectively reducing losses. |
