Considering the economic and technical requirements of power grid planning and the geometric characteristics of Voronoi diagram, a calculation geometric method for locating new substations and dividing power supply areas based on V-diagram is proposed. By using the influence range characteristics, maximum hollow circle characteristics and local dynamic characteristics of the V diagram, it is possible to ensure that the substation is located in the load center, and realize the automatic optimization of the site selection of the new substation and the optimal division of the power supply area of each substation. This calculation method provides a new research idea for solving the problem of optimal planning of substation. The example results show that the calculation geometry method has certain validity and rationality.
