EDD's Integrated System Model

At Electrical Distribution Design, we specialize in smart-grid solutions that improve operational performance, plan for future requirements and implement next generation designs. The Integrated System Model (ISM) is a paradigm shift for the utility industry where now the same single model will support all engineering, operating and control functions throughout the company.  No more “syncing” disparate models that are customized for each user group.  Most clients start by using ISM to solve a specific problem, and then expand its use into other domains.

  • Scope
  • Size
  • Speed
  • Savings


At EDD we believe that smart grid planning is the ability to model the system as a whole. The scope of the model can include Transmission, Substation,  primary and secondary Distribution, customer load and system measurements; and, the ability to solve the model in real-time.  The ISM software readily handles 3-phase network models that contain many loops.  EDD’s Circuit Server technology provides the easiest model management in the industry, providing solutions for engineers, operators, field crews, account managers, storm personnel and asset managers.



With an ISM, size doesn’t matter. Clients can merge any number of systems, run any number of applications, and analyze any number of models for comparison.  Models are easily displayed and manipulated over land-based models, such as Google Earth, Bing Maps and GIS.  The ISM is a “physics-based” model of your system, which we closely integrate with a utility’s “physical-GIS” model.



The math behind the model allows solutions to be attained at unrivaled speed. EDD’s ISM uses iterator-based algorithms which naturally support distributed computations. This allows clients to solve more complex problems (involving millions of nodes) many times faster than matrix based approaches.



Most importantly, an Integrated System Model will lead to significant savings. Since any of your data or algorithms can be attached to the ISM and used in conjunction with all other data and algorithms, a truly collaborative environment is created. This eliminates throw away studies, fragmented solutions, and redundant data and interfaces. The ISM will allow for a common model for design, planning, operation and control, which is an identified key smart grid challenge. More time spent analyzing alternative solutions to problems rather than gathering data and creating “from scratch” solutions will save you effort, time, and money.
