About OpenFMB™

The Open Field Message Bus™ (OpenFMB™) is part of SGIP’s EnergyIoT™ initiative, bringing the IoT and advanced interoperability to the power grid. It is a framework for distributed intelligent nodes interacting with each other through loosely coupled, peer -to-peer messaging for fielded devices and systems at the grid edge. It is simply the application of industrial internet technologies and techniques to enable the Smart Grid. The OpenFMB™ framework provides a specification for power systems field devices to leverage a non-proprietary and standards-based reference architecture, which consists of internet protocol (IP) networking and Internet of Things (IoT) messaging protocols.

The framework supports Distributed Energy Resources that communicate based on a common schematic definition and then can process the data locally for action (control, reporting). OpenFMB™ supports field-based applications that enable:

Scalable peer-to-peer publish/subscribe architecture
Data-centric rather than device-centric communication including support for harmonized system and device data
Distributed logic as well as centralized logo

Standardization Efforts

Using the highly successful Green Button PAP as a template, the SGIP contacted the North American Energy Standards Board (NAESB) to create an OpenFMB™ task force to draw upon the experiences of OpenFMB™ simulations, tests, and interoperability demonstrations and develop an initial OpenFMB™ framework by early 2016. NAESB OpenFMB™ meeting schedules, agendas, and other documents are available on the NAESB website.

The first standards deliverables are an OpenFMB™ specification and reference architecture using the microgrid use cases as an example. The project plan has a draft completion date in December 2015, and a NAESB Board ratification vote in 2016Q1.

Figure 2: OpenFMB™ Logical Architecture

The logical architecture for the specification is a layered approach with the following layers:

1.OpenFMB™ Pub/Sub layer – supporting multiple protocols such as DDS, AMQP, MQTT and other publish/subscribe middleware clients
2.OpenFMB™ Interface layer – supporting multiple information models and profiles, configurations, and interaction patterns
3.Application layer – supporting field applications and equipment/protocol-specific adapters for protocols such as Modbus, IEC 61850, DNP3, C12, CoAP, XMPP, and others
OpenFMB™ Live Public Demonstrations

The SGIP’s OpenFMB™ team recognizes that “seeing is believing”. That’s why we have scheduled multiple opportunities for interested parties to come see OpenFMB™ in action. Be sure to check out our microgrid use case EnergyIoT™ OpenFMB™ demonstrations below:

OpenFMB™ Meeting Information and Future Activities

The OpenFMB™ project participation is open to all SGIP members. If you are interested in joining the SGIP, visit our Become a SGIP Member Page. One hour OpenFMB™ team meetings occur weekly on Thursdays at 2 PM Eastern. The team also meets in person as necessary, typically at quarterly intervals, at test bed, R&D;, and utility locations. The OpenFMB™ project is Co-Chaired by Stuart McCafferty, SGIP Vice President of Operations, and Stuart Laval, Duke Energy Manager of Emerging Technology Development.

Utilities, Smart Grid vendors, and test bed organizations are highly encouraged to participate in this exciting EnergyIoT™ interoperability effort.

The OpenFMB™ project team is developing a project plan and schedule for next year. Our current plan is to identify new use cases (currently exploring Distribution Automation, DER, and other distribution system-related business drivers), and focus our efforts around an Application Programming Interface (API) and cyber security. More details will be provided as the team reaches consensus.
