Abstract

The invention relates to a cluster division method considering flexible supply and demand balance and response speed. The method comprises the steps: firstly, analyzing the influence of wind-solar grid connection on a load, and studying the capability of a distributed power supply and a load thereof in a cluster for providing flexibility for a system; secondly, providing a comprehensive index combining a distributed power supply cluster flexibility supply and demand balance index, a response speed index and a modularity index; and finally, dividing the distributed power supply cluster by adopting an improved genetic algorithm. Compared with the prior art, the method has the advantages that the cluster structure can be guaranteed, the supply and demand balance of the flexible resources in the cluster can be guaranteed, the autonomous capability of the cluster is improved, the response characteristic of the flexible resources in the cluster is fully played, and the capability of the cluster participating in system frequency modulation is improved.

Description

technical field [0001] The present invention relates to the technical field of distributed power supply regulation, in particular to a method for distributed power supply to participate in system frequency modulation and peak regulation, and in particular to a cluster division method that considers flexibility, supply-demand balance and response speed. Background technique [0002] In order to achieve the goal of carbon neutrality, it has become a trend to vigorously develop renewable resources to replace non-renewable energy. At the same time, the integration of large-scale renewable energy will bring great challenges to the planning and operation of traditional distribution networks. [0003] As the proportion of distributed generation in the grid continues to increase, it causes many problems, such as node voltage violation and reverse power transfer. It increases the difficulty of frequency regulation, voltage regulation and peak regulation of the power grid. In additi...
