Power grid topology optimization method and system based on alignment strategy and force steering algorithm

The invention discloses a power grid topology optimization method and system based on an alignment strategy and a force steering algorithm, and belongs to the technical field of power grid topology drawing. The method comprises the following steps: acquiring an original power grid topological graph of a power grid, and performing gridding division on the original power grid topological graph to generate a gridding original power grid topological graph; key nodes, cross points of grid lines and edge cross points in the gridding original power grid topological graph are determined, and coordinates of the key nodes, the cross points of the grid lines and the edge cross points in the gridding original power grid topological graph are determined; and keeping the coordinates of the key nodes unchanged, and according to the coordinates of the intersection points of the grid lines and the edge intersection points, moving or adjusting the target nodes according to an alignment strategy or a force steering algorithm, s
