Multi Domain Ontology Model Fusion and Interoperability Method of Digital Twin in Distribution Network

The digital twin of distribution network covers models including topology, geography, space, production, operation, control, measurement, marketing, electric field, etc. There is no unified rule framework for multi domain ontology modeling methods, and there is an urgent need for model fusion and comprehensive utilization. This article focuses on the cross domain joint modeling problem of distribution network ontology, conducts research on the fusion method of multi domain ontology models of distribution network digital twins, proposes a multi type model resource fusion and comprehensive utilization method with equipment and facilities as the core, integrates business models and power grid models, studies multi domain ontology model fusion interoperability technology for digital twins, and realizes the comprehensive utilization of distribution network digital twin model resources.
