AI Technical Summary

Technical Problem

Existing technologies fail to effectively integrate ground motion, facility vulnerability, topographic conditions, and socioeconomic factors when assessing the seismic risk of urban power systems. They also lack dynamic modeling capabilities, making it difficult to quantify the economic losses and social stability risks associated with power outages, thus affecting post-disaster recovery efficiency and resource optimization.

Method used

Using multidimensional data analysis methods, an earthquake damage assessment database is constructed. By combining ground motion parameters, power facility vulnerability functions, topographic elevation models, and socioeconomic data, the power supply gap rate and repair costs are dynamically calculated. The power supply restoration process under multiple scenarios is simulated, economic losses and social stability risks are quantified, and risk zoning and repair strategies are generated.

Benefits of technology

It has achieved comprehensive assessment of the entire county and multiple voltage levels, improved the accuracy and adaptability of the assessment, dynamically quantified the impact of terrain and socio-economic factors, supported multi-scenario simulation, optimized resource scheduling, and enhanced the resilience and emergency management capabilities of the power system.

Abstract

The present application belongs to the field of urban power system operation and maintenance technology, and discloses a city power system earthquake disaster resilience determination method and system based on multi-dimensional data analysis. The present application obtains the earthquake parameters, power facility information, geographic data and social economic data of each county in the city, and constructs a multi-source heterogeneous evaluation database. Based on the seismic motion parameters and the power facility vulnerability function, the damage probability and the expected loss rate of the function of different voltage level substations and transmission lines are calculated, and the residual function matrix of regional power supply is generated. Combined with the real-time power demand model and the power supply capacity recovery curve, the post-earthquake power supply gap rate is calculated, and the influence of the terrain characteristics on the transmission line repair cost is evaluated to quantify the influence of the earthquake on the economic loss, the affected population and the social stability. The present application can effectively improve the resilience and risk management capability of the power system in the earthquake disaster, and provide technical support for the post-earthquake power rapid recovery and resource optimization allocation.
