The “double carbon” strategy has brought attention to the importance of integrated energy system management in parks for improving energy utilization efficiency, reducing energy consumption costs, and achieving intelligent management. This paper introduces an integrated energy system framework for a park that uses cloud-based edge devices and focuses on managing carbon emissions and operational efficiency based on carbon emission flow. This framework aims to enhance data processing and energy management efficiency, decrease carbon emissions, and improve economic performance by utilizing resource pre-allocation through edge computing and centralized management via cloud platforms. The paper summarizes critical technologies associated with this framework, including carbon emission prediction, data security assurance, operational efficiency maintenance, and pressure reduction on energy storage facilities to optimize carbon emission solutions. These technologies support the low-carbon development and optimal resource utilization of integrated energy systems, providing a novel approach to sustainable development and a reference for future technological advancements.
