Method and system for optimizing and regulating distribution network power supply reliability indexes

Abstract

The invention provides a method and a system for optimizing and regulating distribution network power supply reliability indexes, which compare the distribution network power supply reliability indexes with predetermined standards to judge whether optimization and adjustment of the distribution network power supply reliability indexes are needed, judge effects on a whole distribution network from the power supply reliability indexes of all transformer substations or subareas to select transformer substations or subareas needed to be adjusted, select power supply reliability index parameters which have large effect on the power supply reliability indexes from the transformer substations or the subareas for adjusting, and can lead the power supply reliability indexes of the whole distribution network to achieve larger optimization until the distribution network power supply reliability indexes obtained by the adjusted power supply reliability index parameters accord with the predetermined standards, the optimum control strategy of the distribution network power supply reliability indexes can be obtained according to the power supply reliability index parameters, and distribution network transformation is conducted based on the optimum control strategy. Through the method and the system, system power supply reliability can be improved to the maximum limit under conditions of given capital, and economic benefit of the system is improved.

Description

technical field [0001] The invention relates to the technical field of reliability index optimization of a distribution network, in particular to a method for optimizing and regulating a power supply reliability index of a distribution network, and a system for optimizing and regulating a power supply reliability index of a distribution network. Background technique [0002] Power supply reliability assessment of power distribution system is one of the important links in the power supply reliability assessment of power system. The power distribution system is the part of the power system that is directly connected to the power grid and the majority of power customers. The reliability of its power supply is a matter of great concern to power supply companies and power customers, so it is also a very important research direction. In the past, the evaluation and prediction of the power supply reliability index of the distribution network mainly relied on human experience, and i...

Problems solved by technology

In the past, the evaluation and prediction of the power supply reliability index of the distribution network mainly relied on human experience, and it was not well combined with the actual situation of the power grid for scientific and quantitative analysis, so it was not accurate.
