Abstract

Embodiments of the present invention provide a method and device for calculating power grid line loss, wherein the method includes: constructing a power grid model based on power grid data; partitioning the power grid model based on the Fast-Newman algorithm to obtain the final partition result; based on the final partition result, calculating the power grid model Decoupling and parallel power flow calculations are performed on each partition in the grid to obtain the power flow calculation results of each partition; based on the power flow calculation results of each partition, the power grid line loss results are obtained. The method and device provided by the embodiments of the present invention partition the power grid model through the Fast-Newman algorithm, have lower time complexity, can realize fast partitioning of large-scale power grids, and ensure the accuracy and rationality of the partition results. In addition, by performing parallel power flow calculations for each partition in the power grid model, the calculation results are highly accurate and real-time, providing strong technical support for real-time calculation and refined management of line losses.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a method and device for calculating line loss of a power grid. Background technique [0002] Line loss is the power loss generated in the process of power transmission, and the line loss rate is an indicator to measure the level of power grid operation and management, and is also an important reference in the planning and construction of smart grids. Line loss calculation can comprehensively reflect the level of power grid planning and design, power grid construction, technological progress, production operation and management level, and is also an important technical management method for power supply enterprises. [0003] At present, the line loss statistics of the power grid mainly use the measured values ​​of the metering automation system. In order to avoid the occurrence of statistical errors, it is necessary to conduct a comparative assessment through theoretical li...
