Dynamic power network topology modeling method and system

Abstract

The invention provides a dynamic power network topology modeling method and system. The dynamic power network topology modeling method comprises obtaining device information of power network devices,configuring device main bodies of the power network devices to be top points, and configuring internal and external connection terminals of the power network devices to be terminal top points, configuring attribute information for each top point and each terminal top point according to the device information; configuring connecting edges according to ownership relationships and connection relationships among the top points and the terminal top points; and connecting the top points and the terminal top points through the connecting edges, and generating a network topology model of the power network devices. By employing the designed dynamic power network topology modeling method, modeling of a large-scale dynamic power network is achieved, the large-scale dynamic power network topology modeling speed is greatly increased, a data basis is provided for subsequent topology analysis, and therefore the topology analysis performance is improved.

Description

technical field

[0001] The invention relates to the field of power network modeling, in particular to a dynamic power network topology modeling method and system. Background technique

[0002] The power system is composed of generators, substations, transmission lines and loads and other power components connected in a certain form. It is a huge, complex and dynamic network. Due to load changes, equipment maintenance, fault tripping, active optimization and other reasons, The topological structure of the power grid often changes, mainly manifested in changes in the operation mode of system components and switches, such as the input or withdrawal of components such as lines, transformers, and generators, as well as bus tie switching and switch switching. Even a local change in the network topology may lead to overloading of the transmission line and voltage limit, and the overloaded equipment may be out of operation under the protection of the system, which will develop into ...
