Implementation of IEEE Standard 1547-2018 for DER Communication Interface using Data Distribution Service

In addition to the functional and technical requirements for interconnecting distributed energy resources (DER) to the power system, IEEE standard 1547-2018 recommends DERs to have an interface capable of exchanging information that supports the functionalities in the standard. In this paper, a publish-subscribe data-centric communication scheme with automatic network discovery is selected to implement the DER local communication interface to support the interoperability requirements for information exchange specified in the IEEE standard 1547-2018. Implementation of the proposed communication scheme over a real communication network shows that the selected communication scheme enables true plug-and-play interoperability by automatically discovering joining DERs, and therefore, enhances the system's scalability.
