Power distribution network topology identification method for high-proportion household photovoltaic access

The invention discloses a high-proportion household photovoltaic access power distribution network topology identification method, which comprises the following steps: constructing all user time sequence vectors and time sequence matrixes under a distribution transformer based on user power and voltage values collected by an intelligent measurement device in a power distribution network and household photovoltaic power and voltage values; establishing a mapping relationship between the time sequence vectors and time sequence matrixes of all users and distribution network information; based on the mapping relation, extracting time sequence characteristics of the user photovoltaic instantaneous permeability data to identify a photovoltaic time sequence; based on the measurement data time sequence model and the identified photovoltaic time sequence segments, constructing a photovoltaic time sequence power convolution model, and identifying a high-proportion photovoltaic access power distribution network topology
