EDD presents at WPI Seventh Annual Energy Symposium: Engineering Impacts from Energy Policy

EDD’s Dr. Jason Bank (Principal Engineer) and James Tarpey (Executive Consultant) will be presenting at the September 28th WPI Energy Symposium.  Their talk will be part of the session:  “State Policies Driving Engineering Changes.”

EDD provides the DEW/ISM advanced network modeling and analysis software product to electric utility clients.  The presentation will center on specific client use cases of DEW/ISM where regulatory policy changes are causing utilities to reinvent how engineers model, analyze, and design distribution systems to integrate increasing levels of Distributed Energy Resources (DER).

DEW/ISM has significant market advantages over traditional engineering software for building and maintaining large detailed Integrated System Models of electric distribution and/or transmission systems.  With DEW/ISM engineers can connect and make use of measurements from AMI, SCADA, PV, storage and other smart devices.  Automation of engineering analysis with DEW/ISM reduces the cost and time required for DER interconnection requests, and provides for more consistent results.

EDD presents at 2017 IEEE PES General Meeting

At the 2017 IEEE PES General Meeting in Chicago, EDD’s Jason Bank was an invited speaker on the panel Advancing Distribution System Modelling Tools for PV Integration. His presentation, DEW-ISM Implementation at PEPCO: A Model and Data Driven Approach to Automating PV Interconnection Studies, covered results from an ongoing project at PEPCO to automate the analysis of PV interconnection studies.  The project at PEPCO starts with the construction of an Integrated System Model of the entire distribution and secondary system. The primary model has 2.4M components and the secondary model has 3.9M components.  The model is updated from GIS, hourly meter data and SCADA.  A production version of the model is maintained in memory to support a multitude of engineering analysis functions that run in the DEW software at very fast speeds on a small processor.  The DEW/ISM solution is integrated to the DER queue manager application to enable automatic analysis of DER interconnection requests.

PEPCO Holdings uses DEW/ISM to Calculate DER Hosting Capacity

Pepco Holdings (PHI) has gone live with their DER Hosting Capacity website http://www.pepco.com/Hosting-Capacity-Map.aspx.  The site enables any stakeholder to view an interactive map to determine how much renewable energy and other distributed energy resources can be connected to the distribution system.  The Hosting Capacity is calculated using the DEW/ISM software from EDD, and the results are displayed on a geospatial interactive map.  The EDD Hosting Capacity algorithm is run against the Integrated System Model of PHI’s distribution system.  The ISM is part of EDD’s software solution.  The ISM is a geospatial power-flow model that includes PHI’s 1.9M metered customers with 8,760 hourly load models for each customer, 2,248 primary circuits, 356,000 distribution transformers with secondary conductors, 49 downtown networks, 338 substations and approximately 65,000 DER representing 731 MW’s.  The advantage of the EDD Hosting Capacity approach using the ISM model is that many thousands of power-flow runs are made so that a highly accurate estimate of hosting capacity can be provided.  For further information about EDD products and services, including Hosting Capacity analysis, please visit our website (www.edd-us.com) or contact us (solutions@edd-us.com) for a product demonstration.

EDD becomes Associate Member in CURENT at University of Tennessee; DEW/ISM to be used in Transmission Networks research

The University of Tennessee has established the Engineering Research Center for Ultra-wide-area Resilient Electric Energy Transmission Networks (called “CURENT”).  The purpose of CURENT is to establish a mechanism whereby the educational and research environment can be used to develop better understanding of electric power engineering and related fields, and simulate industrial innovation.

Electrical Distribution Design, Inc. of Blacksburg, VA has been invited and has agreed to join CURENT as an Associate Member as part of the Industrial Partners Program.  EDD will provide DEW/ISM software licenses and technical support to the CURENT team.

Member organizations include the University of Tennessee, National Science Foundation, Department of Energy and the State of Tennessee.  Partnering Universities include Rensselaer Polytechnic Institute, Northeastern University and Tuskegee University.

The DEW/ISM (Distributed Energy Workstation/Integrated System Model) is a commercial software program for advanced modeling and analysis that is being used by leading electric utilities and related businesses.  DEW/ISM provides integrated system models for unbalanced three-phase power flow solutions of transmission, substation and distribution systems of any size and complexity.  DEW/ISM is the only power flow software that utilizes Graph Trace Analysis (GTA) for modeling and analyzing electric networks.  EDD’s Chief Technical Officer and Virginia Tech professor, Dr. Robert Broadwater, is the inventor of GTA.

Transmission, Substation and Distribution System Modeling: Millions of Components and Billions of Measurements

At a recent NREL seminar, EDD’s Chief Technical Officer, Dr. Robert Broadwater presented to NREL staff on the capabilities of the DEW/ISM software from EDD to model large Integrated System Models of utility electric grids.  The DEW/ISM software package is an advanced modeling and power flow analysis solution that is in commercial production at leading US utilities.

DEW/ISM is the only modeling software that employs the Graph Trace Analysis (GTA) approach.  GTA was developed at Virginia Tech to meet the needs of utilities to integrate large complex models with vast amounts of measurement data.

Technical advantages of GTA include: (1) eliminate processing of topology matrices; (2) solve Kirchhoff voltage & current law at every component in the model; (3) no simplification, the model accurately reflects field conditions; (4) readily supports distributed processing; (5) use the same techniques for transmission, substation, distribution in combined or separate models.

Business Advantages for utilities who use DEW/ISM include: (1) maintain an accurate physics-based and geospatial Integrated System Model of the entire system; (2) utilize AMI, SCADA and other measurements directly in power flow analysis; (3) readily accommodate all smart grid requirements for DER, storage, automation, microgrids, and voltage management; (4) automate engineering analysis for interconnection studies, hosting capacity, feeder efficiency and more; (5) cleanup GIS topology errors and support multiple modeling requirements from one accurate source.
