A Hierarchical Management Method of Multilevel Power Grid Fine Model Based on Variation Mode

Abstract

The invention discloses a variation quantity mode-based hierarchical management method for a fine multistage power grid model. The accuracy and the efficiency in generating, maintaining and applying a power grid model are ensured by adopting three different corresponding methods according to three different stages during the interaction process of various stages of power grid models. During the process of generating the fine power grid model, only an equipment model and a network topology structure model within the scheduling authority scope are analyzed by identifying a scheduling authority; during the maintaining stage, the process of generating and analyzing the power grid model and the interaction process of data files based on the variation quantity are accomplished through a multi-version management technique of the databank and the resource end control to the data change; and during the data application stage, the change information of the power grid model is identified, the information about the variation quantity of the fine power grid model is obtained, the process of generating and analyzing the power grid model based on the variation quantity and the interaction process of the data files are accomplished, and application data are generated through the multi-version management technique of the databank. The accuracy and the efficiency in analyzing and splicing the power grid model are improved.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a layered management method of a multi-level power grid fine model based on a variation model. Background technique [0002] At present, power system dispatching generally adopts a hierarchical dispatching method. Different levels of dispatching units govern power grids of different scopes. It is a model of the same interconnected grid. In order to ensure the consistency and sharing of grid model data, it is necessary to establish a centralized fine model of the whole network for this unified interconnected grid, and to be able to manage and manage the fine model of the whole network hierarchically. maintain. In the present invention, the refined grid model refers to a grid model without an equivalent network described according to the actual grid physical topology structure and the actual grid equipment model. [0003] In line with the principle of "source end maintenance, global ...
