Strong local power grid structure determination method and device, equipment and storage medium

Abstract

The invention relates to a strong local power grid structure determination method, device and equipment and a storage medium. The method comprises the following steps: determining a first weighted adjacency matrix according to a power grid topological structure chart and related information of the power grid topological structure chart; according to the first electric power parameter of each user, the residual capacity of each local guarantee power supply and the first weighted adjacency matrix, determining a target path from each user to a target local guarantee power supply in the power grid topological structure diagram; and combining the target paths of the users, and determining the minimum grid structure of the strong local power grid. According to the method, the target local guarantee power supply and the target path capable of supplying power corresponding to each user can be quickly and efficiently calculated, and then the minimum grid structure of a strong local power grid can be obtained by merging and deleting, so the method is efficient and high in accuracy, and the determination of the minimum grid structure of an urban power grid with a large number of important users and a complex grid structure can be met.

Description

technical field [0001] The present application relates to the technical field of power systems, in particular to a method, device, equipment and storage medium for determining the grid structure of a strong local grid. Background technique [0002] Building a strong local power grid is a key measure to ensure that the security load of important users is not powered off, and the non-security load is quickly restored. Studying the minimum network structure of a strong local power grid is an important part of "less but more precise" control of construction scale and promotion of differentiated design. [0003] At present, the construction of a strong local grid network structure mainly relies on manual methods to sort out the substations and contact lines between them according to the distribution of important users and local guaranteed power sources. However, manual analysis is difficult to apply to urban power grids with a large number of important users and complex grid str...
