AI Technical Summary

Technical Problem

Existing technologies, when addressing the issue of coordinated operation of distribution substations under a high proportion of renewable energy access, rely on a single evaluation dimension, making it difficult to comprehensively reflect power supply reliability, quality, and electricity consumption characteristics. They also lack a flexible interconnection matching mechanism and fail to fully consider geographical proximity, leading to increased complexity in distribution network operation and insufficient renewable energy absorption capacity.

Method used

By constructing a multi-level evaluation system, historical energy consumption data of the target transformer area is obtained, problem labels are generated, geographically adjacent candidate transformer areas are screened, risky and unstable transformer areas are eliminated, the comprehensive matching degree is calculated, and the most suitable transformer area is selected for flexible interconnection.

Benefits of technology

It achieves precise matching between distribution substations, improves the stability of the distribution network and the capacity for renewable energy absorption, reduces line construction costs, improves decision-making efficiency, and ensures the overall operational stability and reliability of the system.

Abstract

The invention discloses a transformer area flexible interconnection matching method and device, a medium, equipment and a product. The method comprises the following steps: acquiring a target transformer area and a problem label and geographic coordinates thereof; by taking the geographic coordinate of the target transformer area as a center, screening out other transformer areas in the geographic range to form a first candidate transformer area set; eliminating the courts with the same preset red line labels as the target courts and / or the problem label severity level reaching a threshold value to obtain a second candidate court set; calculating a label score and a physical distance score of each transformer area in the second candidate transformer area set; and calculating a comprehensive matching degree according to the calculated label score and distance score, and selecting the transformer area with the highest comprehensive matching degree as a matching transformer area which is flexibly interconnected with the target transformer area. According to the method, the most suitable adjacent transformer area can be matched for the target transformer area for flexible interconnection, and the operation stability and the new energy consumption capability of the power distribution network are improved.
