Power supply aggregation and clustering method in new energy cluster power grid

The invention relates to a power supply aggregation and clustering method in a new energy cluster power grid, and the method comprises the steps: obtaining a shortest electrical distance matrix between any two nodes of a to-be-aggregated region of the power grid, and considering the constraint of a tie line, and determining M aggregation centers; representing a correlation index between any two nodes in the region by a corresponding element in the shortest electrical distance matrix to obtain a correlation index matrix; based on the correlation index matrix, calculating correlation indexes of each type of power supply and the M aggregation centers, determining the aggregation center to which each power supply belongs according to the correlation indexes, and obtaining a pre-grouping result; and considering the net rack constraint, taking the minimum two constraints of the net rack constraint and the tie line constraint as a basis, and re-clustering the nodes which are geographically far away from each other t
