Abstract

The invention discloses a method and system for estimating reasonableness of large power grid planning power flow. The method comprises the steps of building a first evaluation index set of running mode data reasonableness of single time; building a second evaluation index set of running mode data reasonableness of a plurality of times; acquiring data quality score of each evaluation index in thefirst evaluation index set at an arbitrary time; acquiring average data quality score of all evaluation indexes in the first evaluation index set at an arbitrary time; acquiring data quality score ofeach evaluation index in the second evaluation index set at the plurality of times; acquiring average data quality score of all evaluation indexes in the second evaluation index set at the plurality of times; and determining integral average data quality score of the first evaluation index set and the second evaluation index set according to the average data quality score of all evaluation index in the first evaluation index set and the average data quality score of all evaluation index in the second evaluation index set.

Description

Technical field [0001] The present invention relates to the field of online safety and stability calculation and analysis of power systems, and more specifically, to a method and system for rationality assessment of planned power flow of large power grids. Background technique [0002] The day-ahead dispatching plan of the power system is an important part of the dispatching operation of the power grid, and a reasonable dispatching plan is the prerequisite and basis for ensuring the safe and stable operation of the power grid. With the advancement of UHV construction and regional grid interconnection, the scale of AC / DC hybrid power grids continues to expand. At the same time, new energy sources such as wind power and photovoltaics are connected on a large scale. The grid operation methods are becoming more and more complex. Need to be more refined and accurate. Checking the safety and stability of the dispatching plan can discover the safety and stability problems in the previo...
