新能源接入石化电力系统安全稳定风险评估体系的创新构建与实践OA

In response to the unique challenges posed by the integration of a high proportion of renewable energy into the power systems of petrochemical enterprises,this paper establishes a safety and stability risk as-sessment system suitable for renewable energy grid integration scenarios in petrochemical plants by comprehen-sively utilizing assessment tools such as HAZOP,LOPA,and BPA.Compared with traditional public power grid assessment,this system highlights the characteristics of petrochemical scenarios and realizes a closed-loop linkage of"risk identification-protection layer assessment-quantitative verification".First,the HAZOP method is applied to systematically identify potential risks and assess risk levels in the renewable energy power station,grid-connection points,and access system.Second,the LOPA method is employed to conduct a semi-quantita-tive reliability evaluation of stability control measures by integrating petrochemical-specific protection layers.Fi-nally,combined with BPA simulation tools,static and transient safety and stability analyses are performed to quantitatively evaluate the maximum renewable energy integration capacity of the system and its stability charac-teristics under extreme operating conditions,and verify the effectiveness of the protection layers.The research outcomes can provide a scientific basis and practical reference for renewable energy planning and secure grid in-tegration in petrochemical enterprises.
