Xtensible Solutions

Xtensible Solutions has been working with a large utility in southern United States to develop an EIM strategy and roadmap for application across multiple SG projects, including distribution system demand response (DSDR), WMS, and meter data integration projects. A key component of the adopted EIM strategy has been development of an IEC 61968/61970 CIM-based enterprise semantic model (ESM) in UML to provide a common model for designing all system integrations. The ESM was built using Xtensible’s MD3i Design Studio, which was also used to generate the XSD messaging specifications. This modeling and design environment facilitated both top-down and bottom-up architecture designs to integrate the CIS, WMS, DMS/SCADA, GIS, FMS, OMS, PI Historian, SAP, MDMS, and meter data collection systems involved in their projects via an enterprise service bus (ESB). For both design approaches, the MD3i Design Studio provides traceability within the ESM to link business processes, integration requirements, data/service models, and physical implementation artifacts (i.e. XSDs and WSDLs). The MD3i Design Studio creates a much-needed flexible modeling environment for this utility on their smart grid integration effort, which involves multiple utilities and multiple vendor specifications.
