Research on Integrated Topology Recognition for Low-Voltage Distribution Substations

We introduce a technique for determining the topology of substations for low-voltage distribution that utilizes dynamic time warping (DTW) distance alongside the Least Absolute Shrinkage and Selection Operator (LASSO) method. Initially, the DTW distance is employed to assess the similarity of voltage curves from various users. Subsequently, the LASSO method is utilized to derive the relevant matrix within the buses of the distribution network. The effectiveness and accuracy of this proposed approach are confirmed through simulation results.
