Abstract: This paper proposed a transmission-distribution coordinated absorption strategy in which the new energy distribution network applied controllable resources to regional self-discipline control, and studied a method for analyzing the reasonable absorption capability of new energy satisfying regional self-discipline characteristics and absorption quality with the given distribution resources. The goal is to handle the situation that the random uncertainty of new energy power generation leads to serious power disturbance of the distribution network to the main network and improve the multi-level orderly absorption capability of new energy in the power system. Firstly, the strategy for implementing the self-discipline operation of the distribution network was unveiled, and the performance indices of self-discipline operation capability were created. Then, the optimal allocation model for the new energy absorption capability of the distribution network was constructed, and the operation behavior model of the distribution network satisfying self-discipline constraints was built based on energy storage, flexible load, and network reconstruction, and solved by the genetic algorithm. The evaluation indices of new energy absorption capability considering absorption quality were proposed and the comprehensive performance of the allocation scheme was assessed by the annual time series simulation. Finally, an economic and technological development zone in Hebei Province was taken as an example for analysis to verify the effectiveness and rationality of the proposed method.

Key words: distribution network, new energy absorption, self-discipline operation, maximum absorption capability, comprehensive evaluation
