Abstract

The invention discloses a Prim's algorithm-based method for reconstructing a distribution network with a high proportion of distributed generation, including the following steps: S1, obtaining the output and the load of the distributed generation the distribution network; S2, constructing a demand response model for regulating the load and the distributed generation output, and regulating the loadand the distributed generation output; S3, constructing a reconstruction model of the distribution network with a high proportion of distributed generation; S4, solving the reconstruction model of the distribution network with a high proportion of distributed generation by using a Prim's binary particle swarm algorithm to obtain a reconstruction result. The method obtains a network reconstructionscheme by constructing a reconstruction model of the distribution network with a high proportion of distributed generation, and using the Prim's binary particle swarm algorithm to solve the model. The distribution network running under this scheme is more economical, safe, and reliable, and has important practical significance for the sustainable development of a power grid.

Description

technical field [0001] The invention relates, in particular, to a method for reconfiguring a distribution network containing a high proportion of distributed power sources based on Prim's algorithm. Background technique [0002] With the rapid development of renewable energy power generation, due to its considerable environmental benefits, more and more distributed power sources based on renewable energy are connected to the distribution network. When a large number of distributed power sources are connected to the distribution network Finally, the power fluctuates greatly, and has randomness and instability. The original power grid topology may lead to an increase in system active power loss and voltage deviation, which cannot well meet the economics of system operation. [0003] From the perspective of power balance, the access of a high proportion of distributed power is a great challenge to the power system. Among the currently existing network reconfiguration methods, ...
