Optimizing Renewable Energy Use in Residential Buildings: A Comprehensive Study of Intelligent Systems

Researchers from Changchun Institute of Technology have conducted a comprehensive study on integrating intelligent systems with renewable energy technologies to optimize energy use in residential buildings. The study, which was supported by Princess Nourah bint Abdulrahman University, explored the potential of coupling residential-scale solar and wind power systems with hydrogen generation and refueling infrastructure. The research presents a technological and economic framework for reducing greenhouse gas emissions and lowering total energy costs in residential buildings.

Key Takeaways:

  • The study evaluates three system setups: standalone photovoltaic (PV), standalone wind, and hybrid PV-wind systems, and finds that all configurations significantly reduce greenhouse gas emissions and lower total energy costs.
  • The levelized costs of electricity (LCOE) for robust solutions range between $0.07190 and $0.1127/kWh, while deterministic models yield LCOEs between $0.0704 and $0.0788/kWh.
  • The research identifies optimal hydrogen production scenarios that enhance system efficiency and economic viability, and analyzes how regional variables such as climate and economic conditions influence system performance.
  • The study underscores the potential of integrating intelligent energy systems with renewable technologies to create resilient, low-carbon residential energy infrastructures.
  • The research highlights the importance of considering cost parameters, discount rates, and uncertainties in resource availability when designing and optimizing renewable energy systems.
  • The study provides insights for tailoring intelligent renewable energy solutions to diverse residential contexts, including those with different climate and economic conditions.

Statistics:

  • The study finds that the hybrid PV-wind system setup reduces greenhouse gas emissions by up to 70% compared to traditional fossil fuel-based systems.
  • The LCOE for the hybrid PV-wind system setup is estimated to be between $0.07190 and $0.0788/kWh.
  • The research concludes that the levelized production cost (LPC) of hydrogen is estimated to be between $35 and $45/kg.
  • The study identifies that the optimal hydrogen production scenarios occur when the cost of electricity is between $0.05 and $0.10/kWh.
  • The research notes that the total energy costs for the hybrid PV-wind system setup are reduced by up to 30% compared to traditional fossil fuel-based systems.
