Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing. figure 1 A flowchart of a method for defining integrity checks for power system grid model boundaries.
[0025] In the present invention, transformers, AC line segments, equivalent loads and equivalent generators are used as boundary definitions between sub-regions of the power system, and boundary definitions are used as constraints for distinguishing internal and external networks under the jurisdiction of power model dispatching. By using breadth-first search The method starts coloring with the internal nodes of the boundary equipment of the power grid model as vertices, and judges the integrity of the boundary definition between sub-area models according to the coloring result, and forms a leakage boundary hint, which is used to supplement the boundary definition, so as to complete the splicing The internal and external network division of the power grid model is finally ...

The invention discloses a method for checking boundary definition integrity in power grid model splicing of a power system. The method is characterized by comprising the following steps of: taking a transformer, an alternating-current segment, an equivalent load and an equivalent generator as boundary definition between subareas of the power system, differentiating partial models of internal and external networks dispatched and administered by power by using a boundary definition method, and performing search and topological dyeing by adopting a breadth-first search method and taking an internal node of a power grid model boundary device as a search vertex; and judging the integrity of the boundary definition between models of the subareas according to the dyeing result, and forming divulgence boundary prompt for supplementing the boundary definition so as to finish division of the internal and external networks of the power grid models to be spliced and realize full-area large power grid model splicing. The method ensures the integrity, validity and practicability of the boundary device definition between the subareas in the power grid model splicing.
Description
technical field [0001] The invention relates to a method for checking the integrity of the boundary definition in the splicing of electric system network models, and belongs to the field of electric system network model processing. Background technique [0002] Accurate, comprehensive, and consistent grid models are the foundation of future smart grids. The operation of my country's power grid is based on the principle of "unified dispatching and hierarchical management", which is an important means to ensure the safe and stable operation of the power system. Model and maintain, and receive and process real-time data under jurisdiction in real-time. [0003] However, as a whole, the power system itself affects each other among its sub-regions. Due to the limitation of the modeling range, the accuracy of various auxiliary analyzes and simulation calculations is affected. In order to achieve the goal of "source maintenance and global sharing", large model stitching is require...
