A Coordinated Planning Method for Distribution Networks Considering Load Transfer Channels

Abstract

A distribution network coordination planning method considering load transfer channels. It includes determining the area, investigating and collecting funds: determining the planning area, and collecting the current status data of the distribution network in the planning area; analysis of the wiring mode of the distribution network; analysis of the load transfer channel of the distribution network; adaptability analysis of typical power supply modes; distribution network coordination performance analysis; judging whether the power supply capacity reaches the maximum and other steps. Effects of the invention: The method coordinates each voltage level of the distribution network and comprehensively considers the load transfer channel, and proposes a typical power supply mode suitable for the regional distribution network, which is conducive to improving the scientificity and pertinence of planning, improving the safety and reliability level of the power grid, and delaying the investment of the power grid. , Improve the utilization efficiency of power grid equipment, so this method is more scientific and comprehensive. This method provides a useful reference for distribution network planners to invest in distribution network, and provides strong technical support for future distribution network planning work. This method is easy to master and operate.

Description

technical field [0001] The invention belongs to the technical field of power distribution network planning, and in particular relates to a distribution network coordination planning method considering load transfer channels. Background technique [0002] As the scale of the power grid becomes larger and the grid structure becomes more complex, there are more paths for load transfer. Generally, the load transfer scheme obtained by experience is a feasible scheme but not necessarily the optimal scheme, and as the number of alternative schemes increases, the work of technical and economic comparison of the schemes will become very large, so the establishment of the corresponding load transfer model and Optimizing decision-making can avoid further expansion of faults and reduce load loss, which is helpful to formulate a reasonable maintenance plan. [0003] In the existing studies on load transfer optimization decision-making at home and abroad, the main objectives of optimizat...
