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.

The “High Penetration PV Integration Handbook for Distribution Engineers” has been released and is available for free download from the NREL website at: http://1.usa.gov/1PTVvxC.
The PV Handbook was written as part of a DOE Sunshot project. Lead authors were Barry Mather of NREL, and Rich Seguin, Jeremy Woyak, Dave Costyk, and Josh Hambrick of EDD. An industry peer review team included representatives from leading US. utilities and universities. Southern California Edison provided circuit models and data for the project.
The PV Handbook is a reference manual for practicing distribution engineers working in North America. It is written to provide engineers with a framework for quantifying the impacts of PV that is being interconnected to the electric distribution system. The handbook will be applicable for utility engineers, PV developers, researchers, and customers when trying to study how to add PV to the distribution system. The PV Handbook is agnostic in regards to which modeling and analytics tool an engineer is using.
EDD is a software and engineering services company headquartered in Blacksburg, Virginia. They are the exclusive owner of the DEW/ISM modeling and engineering analysis software. EDD has developed a full suite of analysis tools within our DEW/ISM software that engineers can use to analyze the impact of connecting PV to the grid. Clients of EDD are using DEW/ISM for PV analysis in the following areas:
- DER Interconnection Studies
- DER Hosting Capacity Analysis
- DER Screening
- DER Data Mapping and Tracking
- DER Service Transformer and Secondary Analysis
- DER Analysis of Meshed Networks
