Abstract

The invention is applicable to the technical field of power grid planning, and provides a topology planning and optimization method for power failure risk prevention which comprises the following steps of: obtaining an original topology and related information of a power grid; determining positions and capacities of a newly-built transformer substation and a newly-built power supply in the power grid; forming an initial first redundant topology according to the original topology, the newly-added nodes and the newly-built line, and forming an initial second redundant topology according to the first redundant topology; obtaining a first optimal topology according to the cost destroy-resistant contribution degree and the second redundant topology; obtaining probability thresholds of differentlevels of accidents of the power grid; calculating the probability values of different levels of accidents of the power grid under the first optimization topology; and obtaining a second optimal topology of the power grid according to whether the first optimal topology meets probability thresholds of different levels of accidents and a fragile line compensation reconstruction condition of the first optimal topology. Manual operation can be abandoned, automatic planning and design of newly-added nodes of the power grid are completely realized, and the working efficiency is relatively high.

Description

technical field [0001] This application belongs to the technical field of power grid planning, and in particular relates to a topology planning and optimization method for power outage risk prevention. Background technique [0002] The power industry is an important basic industry in the development of the national economy, and the power grid is the link between the power supply and the user, providing important support for the development of the national economy. As my country's urbanization process continues to accelerate, load demand and installed capacity of power generation increase rapidly, and the pace of power grid construction continues to accelerate. At the same time, the power grid is also facing more and more risks, and cascading failures at home and abroad occur from time to time. As an important public infrastructure, the power grid plays an important role in optimizing resource allocation, ensuring energy security, and meeting the needs of economic and social...
