Abstract

This invention provides a method and apparatus for optimizing power grid cable routing paths. The method includes: performing load analysis on the geographical distribution data and electricity consumption data of the power grid system to generate load area types and corresponding weight data for each area type; assessing the fault propagation risk of power grid nodes in the power grid system based on the load area types and weight data, and generating cable capacity schemes based on the risk assessment results; generating a candidate path set based on the load area types, weight data, and cable capacity schemes through a multi-objective balancing mechanism and an adaptive path growth algorithm; and evaluating and optimizing the candidate path set under various preset simulation scenarios to generate a power grid cable routing scheme. This invention comprehensively considers the characteristics of power grid load distribution, fault propagation risk, and system resilience, and can generate cable routing schemes that adapt to complex load environments and have fault resistance capabilities, significantly improving the reliability and stability of the power grid system.
