Abstract

The invention relates to a cluster division method considering flexibility supply-demand balance and response speed. Firstly, the influence of wind-solar grid-connection on the load is analyzed, and the ability of distributed power sources and their loads in the cluster to provide flexibility for the system is studied; secondly, the distributed power cluster flexibility supply-demand balance index, response speed index and module are proposed. The comprehensive index combined with the degree index; finally, the improved genetic algorithm is used to divide the distributed power cluster. Compared with the prior art, the present invention can not only ensure the structure of the cluster, but also ensure the balance between the supply and demand of the flexible resources in the cluster, improve the autonomy of the cluster, give full play to the response characteristics of the flexible resources in the cluster, and improve the efficiency of the cluster participation in the system. FM capability.

Description

A Clustering Method Considering Flexibility Supply-Demand Balance and Response Speed technical field The present invention relates to the technical field of distributed power supply regulation, in particular to the frequency regulation and peak regulation of distributed power supply systems. The method specifically relates to a clustering method that considers the balance of supply and demand for flexibility and response speed. Background technique In order to achieve the goal of carbon peaking and carbon neutrality, vigorously developing renewable resources to replace non-renewable energy has become a trend. potential. At the same time, the access of large-scale renewable energy will bring great challenges to the planning and operation of traditional distribution networks. [0003] As the proportion of distributed power generation in the power grid continues to increase, it has caused many problems, such as node voltage out-of-limit and reverse power transfer. It in...
