Description
technical field [0001] The invention relates to the technical field of distribution network optimization, in particular to a distributed distribution network optimization and reconstruction method. Background technique [0002] The distribution network is composed of overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensators, and some auxiliary facilities. In the current actual distribution network reconstruction process, there are many switch decision variables. Strict mathematical The model belongs to nonlinear non-convex programming, which is a non-deterministic polynomial problem. Problems such as distribution network reconfiguration and fault location are currently solved by multi-application group intelligent optimization algorithms, but a large number of infeasible solutions that do not satisfy the network topology constraints are easily generated during the optimization process. The voltage and topology will change, re...
