D2 – Residential Communication Protocols

Project Number DR18.12 Organization SCE End-use Whole Building Sector Residential Project Year(s) 2018 - 2021
Description
EPRI is utilizing internal resources in this supplemental program agreement to address specific EM&T focus areas for renewable integration, CS/T&D coordination, innovative residential DR technologies, ZNE market assessment for grid impacts, CEC EPIC DR-related activities at EPRI, and tech transfer of EPRI activities for SCE programs related to EM&T goals. This effort will enhance SCE’s future opportunities for customer engagement and is in alignment with SCE’s technology road map. The Project will be examining communications strategies for “connected” residential electrical end uses for their ability to be harmonized with SCE Grid Mod technologies such as IEEE 2030.5 (SEP2)and DNP3 (IEEE 1815). This project will review architecture and use cases of OpenADR 2.0B (IEC 62746-10-1) as a parallel secure platform as well as ANSI CTA-2045 and ISO/IEC 15116 V2G. Coordinated by the EPRI cyber team
Project Results
This report describes the communication protocols and networking technologies in use or emerging for control of residential Demand Response (DR) resources. It describes three important application-layer (functional) protocols that are the subject of emerging grid codes and standards: OpenADR, IEEE 2030.5, and CTA-2045. It also provides a general overview of four important messaging services that may be used by DR protocols: eXtensible Messaging and Presence Protocol (XMPP), Message Queuing and Telemetry Transport (MQTT), Constrained Application Protocol (CoAP), and Data Distribution Service (DDS). New and emerging telecommunications services available for use by DR protocols, such as 5G cellular, low-earth-orbit satellites, and cloud-based proprietary systems, are also included. Descriptions and comparisons of the protocols are provided, based on the Open Systems Interconnection and Internet models. Cyber security of the protocols is described, and a bibliography focused primarily on relevant EPRI research publications is included.  Descriptions and comparisons of the protocols are provided, based on the Open Systems Interconnection and Internet models.
