研究目的
To evaluate and compare the performance of a smart renewable energy based microgrid system with a traditional energy supply system in terms of energy consumption and pollutant emissions.
研究成果
The proposed renewable energy based microgrid system significantly reduces energy consumption and pollutant emissions compared to the traditional energy supply system, demonstrating its potential for sustainable building energy solutions. Future studies should include life cycle assessment and economical analysis for a comprehensive evaluation.
研究不足
The study focuses on a specific demonstration project in Xining City, which may limit the generalizability of the findings to other regions or building types. Additionally, the economic analysis and life cycle assessment of the systems were not covered, suggesting areas for future research.
1：Experimental Design and Method Selection:
The study involved the design and application of a smart renewable energy based microgrid system composed of solar photovoltaic, air source heat pump, and energy storage subsystems. The performance was compared with a traditional system relying on electricity grid and natural gas.
2：Sample Selection and Data Sources:
The demonstration project was located in Xining City, Qinghai Province, China, involving a two-floor building with specific thermal parameters and energy systems.
3：List of Experimental Equipment and Materials:
Included solar photovoltaic subsystem (32kWp), air source heat pumps (10 units, 40kW total), and a battery (100kWh capacity).
4：Experimental Procedures and Operational Workflow:
The system's operation was simulated using DesignBuilder load simulation software, with parameters set according to Chinese National Standard GB50189-
5：Data Analysis Methods:
20 Energy consumption and pollutant emissions of both systems were compared to evaluate the microgrid system's superiority.
