For many years the electric grid has been controlled centrally: data from remote devices is collected at near real-time rates, and stored in a centralized database where it is federated for use by applications. The increasing deployment of distributed energy resources (DER) is acting as a catalyst for grid modernization, pushing the power grid toward a decentralized, edge-autonomous model.
To manage the dynamic complexities of this new model we must move beyond purely centralized control. Certain control decisions need to be made at or near the edge, data needs to be federated for use by devices in the immediate area and then shared with multiple locations, and security needs to be enhanced for modern cyber threats.
With any design challenge it is prudent to seek out the best solutions to have solved similar problems in related environments, furthering those solutions as appropriate. The Industrial Internet Consortium (IIC) was formed in 2014 to address the many challenges faced by industries undergoing similar fundamental change. With more than 250 member companies, the IIC focuses on three key areas: interoperability between devices and applications from the edge to the cloud, end to end security of the systems, and a common reference architecture across multiple domains and industries. The IIC has published detailed guidance in all of these areas.
The IIC studied the challenge of secure, interoperable data connectivity for IIoT systems, publishing the Industrial Internet Connectivity Framework (IICF) document to provide guidance to IIoT systems developers and standards bodies. Our proposal leverages this work and its insights. In the pages that follow, Real-Time Innovations (RTI), The Glarus Group, Intel, and PingThings detail the functionality of our interoperability-focused submission to the DER Plug-and-Play Challenge; including where and how it will be deployed, the functionality to be demonstrated and how this architecture supports and enables a foreseeable future.
With particular focus on the ESI and to achieve maximum performance, flexibility, and security, this proposal aligns the ESI function using IIC guidance in the form of a layered databus system architecture, using a local databus for enhanced interoperability. In addition, this proposal brings in IICF guidance on core connectivity standards DDS and WebServices, combines it with industry standards OpenADR and IEC 61850, and describes a highly secure, flexible, scaleable ESI architecture.
