Power distribution network topological structure optimization method integrated with impedance attribute

The invention belongs to the technical field of power grid topological structure optimization methods, and particularly relates to an impedance attribute integrated power distribution network topological structure optimization method, which comprises the following steps of: determining a power grid impedance topological structure, and obtaining coordinate values of nodes of a high-dimensional space-time topological network in high-dimensional space coordinates; designing a mapping surface in the high-dimensional space coordinates; according to the method, the network with the optimal correlation degree and topological structure characteristics with the corresponding impedance topological network is constructed by utilizing the high-latitude space-time topological network through optimal projection plane selection and correlation screening; one or more time-space topology networks capable of directly representing the impedance topological relation between the nodes are determined, the difficulty of projects or
