Adaptability Evaluation Method of Distribution Network Considering Flexibility Resource

As distributed energy storage, electric vehicles, adjustable loads, micro-grid clusters, 5G base stations, data centers and other flexibility resource clusters are connected to the distribution network, it has become increasingly important to carry out their adaptability assessments to guide distribution network planning. First, the index system is divided into two levels: macro demand index set and micro evaluation index set. Among them, the macro demand index set is the macro appearance of the distribution network, and the micro evaluation index set represents the micro factors. There is a close relationship between them. The application analysis in the numerical example shows that the method has strong practicability and is of great significance for evaluating the large-scale access of flexibility resource clusters to the distribution network, and analyzing and identifying the operation status and weak links of the power grid.
