| Abstract |
In the context of global carbon neutrality, park public buildings, characterized by high energy consumption , urgently require the establishment of a low-carbon energy supply system. Sinopec Star CO., LTD. has developed a“geothermal +”integrated energy system centered on geothermal technology, complemented by photovoltaic (PV), solar thermal, energy storage and other clean energy utilization technologies. The system’s high efficiency and energy-saving performance have been validated through demonstration projects, including a pilot park in Xiong’ an and an office park in Beijing. In project applications, the system integrates easy-to-develop advantages of shallow geothermal energy and the renewable characteristics of solar energy. Through multi-energy complementation optimization, source-grid-load-storage coordination, and full lifecycle management, it forms a technical path of "cooling and heating supply - solar thermal conversion- intelligent dispatch" and establishes a microgrid system of "PV + energy storage + charging" to achieve dynamic balance of energy supply and demand. This approach provides a globally replicable solution for low-carbon energy supply in park public buildings，as a pathway to actively develop zero-carbon parks. |
