Problems solved by technology

First, this approach to planning is not particularly effective if planners are primarily concerned with reducing costs or with limited budgets
Second, although this accident-based planning approach enumerates and addresses every possible one- or two-device outage scenario, in terms of equipment load (peak load/capacity), the ) is higher than the conventional level, the reliability level of the system level cannot be ensured, because the method fails to co

Abstract

The invention discloses a grid division method of power distribution network gridding planning. The method comprises the following steps of status assessments of gridding power distribution networks;demand forecasting of gridding electric power; planning of technical principles and schemes; planning of sites and channels; investment estimation and planning assessments. The method accurately locates problems existing in the power distribution networks to each grid, each grid can be examined under a magnifying glass to ensure that the existing problems can be solved through investments, and accurate delivery is achieved.

Description

technical field [0001] The invention relates to the technical field of distribution networks, in particular to a grid division method for distribution network grid planning. Background technique [0002] The distribution network directly faces customers, not only undertaking the mission of fulfilling social responsibilities, but also related to the economic benefits of enterprises. The foundation of my country's distribution network is weak. In history, the medium and low voltage distribution network was basically built according to the needs of users, and was greatly influenced by investors. Its grid structure and power supply reliability have always lacked standardized management and specific analysis. At present, each region has consciously formed a grid structure suitable for its own grid development needs based on the actual situation of its own grid development and according to the comprehensive factors such as the level of economic development, grid planning ideas, po...
