Application of Directed Graph Algorithm in Formula Relationship of Power Grid

In the operation of the power grid, the amount of data is large, and the intricate relationship between the data formulas brings hidden dangers to the operation of the power grid. In order to solve the problem, this paper uses directed graphs to show the relationship of formulas in the power grid. By optimizing the rank, node order, and edge length of the graph, the complex formula reference relationships are converted into directed graphs to realize human-computer interaction. The practical application shows that this function can effectively reduce the working pressure and risk of disoperation of the staff in the operation of the power grid, and has positive significance for the safe and stable operation of the power grid.
