ResearchSmart Grid Semantic Model Communication among devices in different smart grid domains Semantic models and canonical data models Minimize the chances of an unintended interpretation of a piece of informationModels can facilitate information transfer between smart grid devicesSome of the most challenging smart grid situations involve the exchange of information across multiple domains (markets, operations, service providers, bulk generation, transmission, distribution, and customers) and among devices and subsystems of diverse complexity. Not only do these types of use cases rely on interoperable communications between such devices, they also rely on the proper configuration and access through several ownership and management boundaries.This white paper describes the use of semantic models and canonical data models (CDMs) as a means of facilitating interoperability across such smart grid collaborations.What’s in the reportReview of inherent perspectives in different classes of smart grid devices and systemsOverview of semantic modelsOverview of CDMsUse of semantic models in the smart gridBenefits of using semantic modelsExisting and emergent CDMs as of 2010
