Analysis of Distribution Network Planning Strategy in Urban Center based on Grid Concept

With the continuous development of the economy, the demand for electricity in all cities has been on the rise. Among them, as the most concentrated area of urban political, economic and cultural activities, the urban central area has the most complex distribution network structure and various voltage levels, and the existing problems are more prominent. Traditional distribution network planning methods can no longer meet the current situation of complex distribution network structure and diverse voltage levels in urban central area. A distribution network planning strategy based on grid concept is proposed. First of all, the hierarchical partitioning method is used to divide the power supply area, distribution area, administrative division, functional area, layout, urban road condition and grid division; After the grid is divided, each grid is taken as a unit and planned according to the grid planning process; By dividing the distribution network area into multiple zones and taking the status and differences of each zone as the planning standard, the grid power supply is finally realized. Compared with the traditional method, the grid planning mode can realize the overall optimization and integration of distribution network resources, which is helpful to improve the efficiency of power grid operation.
