Sustainable production-oriented systematic-dynamic assessment framework for integrated risks in China's energy internet

Amid global low-carbon transition and China's dual-carbon strategy advancement, the Energy Internet (EI), as a core platform for energy transformation, faces complex systemic risks due to cyber-physical integration, multi-energy coupling, and socio-environmental interactions, threatening its safe operation and sustainable production. Existing studies mostly focus on static assessment of single subsystems, lacking integrated analysis of multi-dimensional risk dynamic coupling. To address this gap, this study constructs a multi-dimensional risk assessment framework covering social-environmental, Cyber-Physical System (CPS), and Integrated Energy System (IES) dimensions, and establishes a dynamic coupling risk quantification model by combining System Dynamics (SD) with entropy weighting method. Validation based on Inner Mongolia's EI demonstration base shows that CPS risks and IES reliability are dominant, presenting an inverse bathtub curve trend, rising initially due to technical bottlenecks, then declining with technological progress and preventive maintenance, while social-environmental risks remain low and gradually decrease. This study uncovers the dynamic evolution mechanisms of coupled risks in EI, the findings provide actionable strategies with practical implications. The multi-dimensional dynamic assessment logic offers a China-oriented policy framework reference for global energy transition, especially for developing countries, bridging the gap between systemic risk theory and sustainable production practice.
