Multi domain information architecture and modeling for Smart Grids

Smart Grids are trending towards integrating Industrial Control Systems (ICS) and other domain systems for efficient operational and maintenance activities and cost savings. However, this integration poses the challenge of modeling information in a multi technology domain such that process data (e.g. voltages) and non-process data (e.g. physical access) are exchanged in an interoperable way. This paper surveys the relevant state of the art and selects Common Information Model (CIM) as standardized information model that suits the needs of such integrated systems. Based on this, we propose interoperable information architecture and methodologies to realize multi domain information modeling.
