Abstract

The invention discloses a cluster division method of a distribution network based on a high proportion of renewable energy, including: 1) abstracting the distribution network into a network formed by nodes and edges; 2) randomizing several nodes in the network Change the first preset value to the second preset value, and obtain several individuals corresponding to the changed network; 3), obtain the cluster performance index of the current individual according to the modularity index and the surplus power index; 4), judge whether the iteration converges ; 5), if yes, use the connection structure of the changed network as the target connection structure; 6), if not, perform individual selection, inter-individual crossover and individual variation processing, and the individual corresponding to the processed network As the current individual, return to step 4) until the target connection structure is obtained. The invention discloses a cluster division device for a distribution network based on a high proportion of renewable energy. By applying the embodiments of the present invention, the system's ability to accommodate renewable energy can be improved through clustering.

Description

technical field [0001] The present invention relates to a cluster division method and device, and more specifically to a cluster division method and device for a distribution network based on high-proportion renewable energy. Background technique [0002] Human concerns about the depletion of fossil energy, energy security and environmental degradation have led to the continuous and rapid development of renewable energy. The resulting power system scenario with a high proportion of renewable energy power generation is attracting widespread attention. Especially in the distribution network in remote areas of our country, with the further strengthening of the national new energy poverty alleviation policy, a large number of distributed renewable energy sources are connected to the grid, and some areas even have a penetration rate greater than 100%, which will bring great harm to the local grid. It has a major impact on the safety and stability of the system, mainly reflected i...
