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.
