Research on Business-oriented Smart Grid Asset Information Modeling Technology

This paper proposes a smart grid asset information modeling language based on domain-specific modeling method, which is used to describe the data specification of smart grid asset account, and is easy for experts in the field of asset management to understand and use. In order to meet the requirements of asset life cycle management, asset objects are described from three dimensions: functional location, product and spatial location, which have the characteristics of flexibility and wide applicability. A meta-model of asset information modeling language is proposed and a modeling tool is implemented. It can be used to model and edit asset account specifications for business personnel. It can be divided into asset classification model, structural model and parameter model. The validity of the proposed modeling language is proved by the case study and large-scale application.
