Abstract
The rapid growth of technologies in smart grid (SG) enables reliable data communication. SG involves many sub-domains each of which involves various types of components and devices which require significant data communication in an efficient manner. Thus, a key success factor for SG lies in reliable data exchange between components and domains. Data Distribution Service (DDS) is a standard for data-centric communication based on a publish-subscribe protocol for distributed applications. DDS enables reliable data communication supported by various features such as quality-of-service (QoS). In this paper, we describe the potential of DDS for SG for reliable and efficient data communication. We first give an overview of DDS and discuss its benefits for SG. We then describe communication requirements and constraints in SG. Finally, we discuss how DDS can be tailored to SG with respect to the requirements and constraints.
