Integrated System Model for Electric Grids

A fundamental concept in software engineering is to discover and model all "fundamental objects". An object-oriented model that includes all fundamental objects in the problem domain can be used to solve all problems in the problem domain. For utility systems such models can contain millions of objects consisting of customers, structures, equipment, and measurements. Here such a model is referred to as an Integrated System Model (ISM). A single ISM may span multiple utility systems and include interde- pendencies. The Distributed Engineering Workstation may be used to build an ISM, that for an electric utility models transmis- sion, sub-transmission, primary distribution, secondary distrib- ution, and all customers in a single model. Using an ISM for both collaborative designs and real time, distributed calculations and control will be discussed. The fundamental software paradigm used to implement ISM technology, generic programming, will be consid- ered. Demonstrations with ISM models will be provided. The pro- gress made in implementing ISM technology at utilities will be reviewed.
