Implementation Details

Energy Data Pipeline

Comprehensive data processing pipeline for Australian energy consumption data:

  • Integration of AEMO (Australian Energy Market Operator) historical consumption data across 5 states
  • Weather data aggregation from Bureau of Meteorology including temperature, humidity, and solar irradiance
  • Data quality assessment with outlier detection, missing value imputation, and consistency validation
  • Temporal alignment and resampling for consistent time-series intervals (30-minute, hourly, daily)
  • Holiday and event calendar integration for capturing consumption anomalies and special periods
# Energy data processing pipeline
import pandas as pd
import numpy as np
from sklearn.preprocessing import StandardScaler

# Load and preprocess energy consumption data
energy_data = pd.read_csv('aemo_consumption_data.csv')
weather_data = load_weather_data()
processed_data = merge_and_clean_data(energy_data, weather_data)

Advanced Time-Series Features

Sophisticated feature engineering for energy consumption prediction:

  • Temporal features: hour of day, day of week, month, season, public holidays, and daylight saving transitions
  • Lag features: consumption values from previous hours, days, and weeks to capture autoregressive patterns
  • Rolling statistics: moving averages, standard deviations, and percentiles across multiple time windows
  • Weather-derived features: temperature bins, cooling/heating degree days, weather severity indices
  • Fourier transform features for capturing cyclical patterns and seasonal harmonics
  • Economic indicators: electricity prices, industrial activity indices, and population density metrics

XGBoost Implementation

Optimized XGBoost model architecture for energy consumption forecasting:

  • Hyperparameter optimization using Bayesian optimization with 5-fold cross-validation
  • Custom objective functions for minimizing MAPE (Mean Absolute Percentage Error) in energy forecasting
  • Feature importance analysis using SHAP values to identify key consumption drivers
  • Early stopping mechanisms to prevent overfitting with validation-based monitoring
  • Multi-output modeling for simultaneous prediction across different time horizons (1-hour, 24-hour, 7-day)
  • Model ensemble techniques combining multiple XGBoost models with different feature sets
