A new energy vehicle charging pile power distribution bearing capacity evaluation method
By constructing a regional carrying capacity correlation chain and identifying high-frequency reconfiguration nodes, and combining the energy replenishment behavior of new energy vehicles, a power distribution carrying capacity early warning is generated. This solves the problem that existing technologies are unable to reflect the actual carrying capacity of regional charging piles, and improves the accuracy of assessment and risk warning capabilities.

AI Technical Summary
The existing assessment methods for the power distribution carrying capacity of new energy vehicle charging piles lack correlation analysis between the historical expansion process and the dynamic energy replenishment behavior of new energy vehicles. This makes it difficult for traditional assessment methods to accurately reflect the actual carrying capacity of regional charging piles, and may lead to problems such as local areas being unable to stably meet new charging demands.
By constructing a regional load-bearing correlation chain, statistically analyzing historical expansion occupancy and backup access records within feeder groups, identifying high-frequency reconfiguration nodes and replenishment fluctuation nodes, and combining migration coupling scores to generate power distribution load-bearing capacity early warnings, the actual load-bearing risks under the condition of continuous growth in regional new energy vehicle charging demand are reflected.
It enables continuous tracking of the evolution of regional expansion structures, identifies continuous expansion capacity degradation issues that are difficult to detect using traditional assessment methods, improves the accuracy of power distribution load assessment during the large-scale construction of charging piles, and provides a basis for charging pile expansion planning and resource adjustment.
