Abstract

The invention discloses a cluster division method of a power distribution network based on high-proportion renewable energy. The method comprises the following steps: 1) abstracting the power distribution network into a network formed by connecting nodes and edges; 2) randomly changing a plurality of first preset values in the network into second preset values, and obtaining a plurality of individuals corresponding to the changed network; 3) obtaining a cluster performance index of the current individual according to the modularity index and the surplus electric quantity index; 4) judging whether the iteration is converged or not; 5) if yes, taking the changed connection architecture of the network as a target connection architecture; And 6) if not, performing individual selection, individual intersection and individual variation processing, taking an individual corresponding to the processed network as a current individual, and returning to execute the step 4) until a target connection framework is obtained. The invention discloses a power distribution network cluster division device based on high-proportion renewable energy sources. By applying the embodiment of the invention, the renewable energy consumption capability of the system can be improved through the cluster.

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...
