In a multi-year effort, the Electric Power Research Institute (EPRI) has facilitated advances in the development of standard functions for enterprise integration of distributed energy resources (DER), bringing inverter-connected distributed energy storage and generation into use as a grid resource. Recent industry efforts have defined a wide range of standard grid-supportive functions that inverters may provide and standard communication protocols that allow these functions to be remotely monitored and managed. These “smart inverter” functions have been codified in the International Electrotechnical Commission (IEC) standard 61850-90-7. After the functions were codified, the next focus was on the ability to aggregate messages to these smart inverters in an enterprise context, so that an edge server termed a DER Management System (DERMS) would manage communication to the devices and provide aggregated information to the other utility systems that need it. This effort focused on developing these enterprise messages (using the Common Information Model and MultiSpeakTM) and then creating a test plan that would provide clarity on the expectations of how these messages would be used.
This whitepaper summarizes the findings of a DER Enterprise Integration Testing workshop facilitated by EPRI and held at the National Renewable Energy Laboratory (NREL) Research Support Facility in Golden, Colorado, on October 28, 2014. This paper describes the journey and major milestones leading up to DER integration testing, including the creation of common functions for smart inverters. The whitepaper describes the findings of the workshop and the next steps associated with this initiative.
