Recurrent Neural Networks: The Foundation
Recurrent Neural Networks (RNNs) are a class of neural networks designed to recognize patterns in sequences of data. Unlike traditional feedforward networks, RNNs have internal memory, allowing them to process sequences by utilizing information from previous inputs. This makes them exceptionally well-suited for time series data analysis, such as electricity consumption forecasting. The model's structure involves hidden layers with self-connections, enabling the retention of temporal dependencies. Key components include input layers, hidden layers (with activation functions like tanh), output layers (often with linear activation for regression), and weight matrices that are optimized through gradient descent and backpropagation.
Tailored Electricity Consumption Management
The Electricity Consumption (EC) management model categorizes power load data into distinct patterns to enable targeted interventions. This study identified several EC modes based on campus building usage: Life Peak Type (residential areas with dual peaks at noon/late night), Recess Peak Type (class hours peaks), Working-Hours Peak Type (daytime single peak in offices/libraries), Meal Peak Type (breakfast, lunch, dinner peaks), Night Continuous Peak Type (lighting systems with consistent night loads), and Peak-Free Type (stable 24/7 loads like server rooms). By understanding these distinct patterns, tailored demand-side management strategies can be implemented, focusing on peak shifting and valley filling through mechanisms like hydrogen storage.
Rigorous Experimental Design
The experimental design involved collecting and preprocessing comprehensive energy consumption data from 15 university buildings, spanning 1.5 years at minute-level granularity, aggregated to hourly intervals. External variables such as meteorological data (temperature, humidity, wind speed) and campus-specific information (class schedules, building attributes) were integrated. A robust missing-value imputation strategy, combining 'similar-day' references and Collaborative Filtering (CF), was used. The dataset was chronologically split into training (70%), validation (15%), and test (15%) sets to ensure rigorous model evaluation and prevent data leakage. Comparative models included Linear Regression, Nonlinear Regression, ARIMA, GM(1,1), and LSTM, all evaluated using MSE, MAE, and MAPE metrics.
Superior Prediction Accuracy Demonstrated
In controlled experiments and actual environmental testing, the RNN-based energy consumption time series prediction model consistently demonstrated superior accuracy. For hourly predictions in a real campus environment, RNN achieved significantly lower MSE (0.124), MAE (0.26), and MAPE (5.75%) compared to Linear Regression (MSE 22.09, MAE 3.33, MAPE 21.48%) and nonlinear regression (MSE 0.223, MAE 489, MAPE 16.32%). This highlights RNN's robustness and reliability in forecasting energy loads, outperforming other comparative models across various metrics for both hourly and monthly predictions.
Effective Peak Shifting with Hydrogen Storage
The hydrogen energy storage peak-shifting EC management model demonstrated significant effectiveness. Before implementing the hydrogen energy peak shifting, the peak energy consumption was about 46 kWh; after adjustment, it decreased to approximately 32.8 kWh, resulting in a 12.9 kWh reduction in daily maximum load. The peak-to-average ratio decreased from 2.04 to 1.46, indicating a smoother load curve. Crucially, the number of periods exceeding the predefined quota (35 kWh) was reduced from three to zero, and the total excess energy was eliminated, all while maintaining total daily energy consumption within an acceptable range (a slight increase of 0.9 kWh, or ~0.2%).
