Launched in March 2018, EPRI facilitated a working group of industry experts in DER integration to identify and publicly document a reference set of control methods for distributed energy resources management systems (DERMS). While prior efforts by the industry focused on developing standard service/functions for DERMS at the device-level (DERMS-to-DER) as well as at the group-level (e.g. DMS-to-DERMS), the goal of this working group was to develop reference control methods for mapping DER group-level to device-level functions. A key output of this body of work to the power industry is a reference set of functions to enable modeling and technical analysis needed to study the business case / value proposition of DERMS. Moreover, it provides a baseline set of functional requirements for DERMS products and its specification that enables consistency in DERMS request for procurement (RFP) across the industry. Finally, as different reference control methods are documented through this initiative, it identifies gaps in the relevant communication standards upstream and downstream of DERMS by evaluating their sufficiency to support reference control strategies.
