Research on Intelligent Design and Application of Comprehensive Energy System Based on Digital Twin Technology

This study takes the comprehensive energy system upgrade project of a certain industrial park in Guangdong as an example to deeply explore the intelligent design and application effect of a comprehensive energy system based on digital twin technology. This method constructs a five-layer closed-loop framework of "perception - modeling - optimization - decision-making - evolution", develops multi-source heterogeneous data fusion and high-fidelity hybrid modeling technology, and designs a collaborative optimization mechanism based on hybrid intelligent algorithms. Through engineering verification, it is found that this solution has a significant optimization effect on improving the operational efficiency and economy of the system, and can solve problems such as insufficient energy cascade utilization, difficulty in multi-energy collaboration, and lagging operation strategies. It has certain promotion significance for improving the comprehensive benefits and intelligent level of regional energy systems.
