Research on Smart Grid Dispatching Control System Based on Model Fusion

Abstract

As the safety operation of power grid becomes more and more complicated, the modeling and application of dispatching control system, which is the core part of power grid operation, is one of the key means to improve the system intelligence. Aiming at the characteristics of complex and dispersed business knowledge of power grid dispatching and control system, a knowledge graph construction method combining bottom-up and top-down was proposed. Firstly, through the steps of knowledge extraction, relationship extraction and data cleaning, different data sources are analyzed to obtain the correlation between the basic platforms of the power grid dispatching control system and form the system structure. Then, the physical modeling method based on Jacobi decomposition is combined with the specific business knowledge to construct the power grid dispatching system business logic knowledge graph. Finally, on the basis of actual cases, some components are numerically verified by the method of data injection, and the feasibility of the modeling method is verified by auxiliary analysis to be applied in the actual business.
