Abstract

The invention discloses a method for constructing an information-driven grid static stability domain boundary. The method comprises the steps that a grid static voltage stability domain boundary equation is constructed; and a parameter tracking method is used to perform prediction correction solving on the boundary equation to acquire a solution set from any boundary point to the entire stabilitydomain boundary and complete the construction of the grid static stability domain boundary. The problem of inaccurate constructing of the grid static stability domain boundary is solved.

Description

Technical field [0001] This application relates to the application field of static voltage security and stability assessment of large power grids, in particular to a method for constructing an information-driven grid static stability region boundary, and also relates to an information-driven power grid static stability region boundary construction device. Background technique [0002] With the continuous expansion of the grid interconnection range and the large-scale connection of a large proportion of renewable energy, the grid has shown more complex random characteristics, multi-source big data characteristics and multi-time scale dynamic characteristics. These characteristics have led to major changes in the operating behavior of the traditional power system, affecting the static voltage stability change characteristics of the traditional power system, making the voltage operation more likely to be near the boundary or even lose stability, causing major power outages. Therefor...
