Research on IES Carbon Emission Monitoring and Control System Based on Digital Twin Technology

The carbon emissions of Integrated energy system (IES) cover all aspects of the energy production, transmission, consumption and storage. The IES carbon emission monitoring and control system (CEMCS) based on digital twin (DT) technology can improve the real-time and accuracy of the system, and is conducive to the overall carbon emission control of IES. Based on DT concept and method, this paper studies the framework and the key methods of CEMCS. The framework was analyzed and constructed from the aspects of source, network, load and storage, and the key methods including the construction of the DT architecture model of carbon capture power plant (CCPP), the data-driven method of direct carbon emission monitoring, the multi-energy carbon flow calculation based carbon emission model (CEF model), and the construction of energy storage carbon emission model. Hoping that this study could provide support for comprehensive carbon emission monitoring and control of IES.
