人-信息-能量耦合的城市能源互联网灾变分析与动态预警

Local, simple and even weak failures and faults of the urban energy Internet can all be transmitted to other subsystems through information and energy spaces, which may in turn lead to catastrophic risks from small to large scale, from single system to multi-system, and from minor accidents to paralysis. There is, therefore, an urgent need to study the various approaches of catastrophic analysis. In the background of the urban energy Internet based on human-in-the-loop energy information fusion, this project aims at quantifying the potential catastrophic risks of the human-information-energy coupling system and realizing dynamic early warning for catastrophe. By focusing on the study of interaction mechanism analysis and hybrid modeling of urban energy internet, this research puts forward a calculation method of urban energy Internet probabilistic energy flow based on the dynamic probability model. Then, according to the safety analysis under multiple uncertainties, which reveals the mechanism of catastrophe propagation and evolution across the human-information-energy space, a catastrophe analysis method of coupling system is proposed. Finally, the comprehensive simulation of urban energy Internet catastrophe analysis and early warning is carried out, and the "catastrophe analysis and dynamic early warning system" is developed to verify the validity of the theoretical methods. The expected achievements of this project can provide theoretical support for the planning and operations of the urban energy internet.
