【 摘 要 】

This paper proposes a grid-based method for distribution network planning. Firstly, based on the analysis of the economic and social development targets and distribution network status in the region, the central area is meshed and classified according to the relevant principles and objectives of distribution network planning as well as the nature and development depth of the land. Load forecasting based on grid layout is carried out to determine the saturated load corresponding to the current planning of the area. Finally, according to the current grid, load forecasting results and planning targets, the target grid and transition grid of the planning grid are determined. The above method is applied to the grid planning of a distribution network in Hangzhou China. The planning index is greatly improved, the target network frame of the distribution network is strong, the power supply range is clear, and the power supply reliability is high, which verifies the effectiveness of the method.
