This document describes the data interface model, application-level communication, managementfunctionalities, and security mechanism for the exchange of data with smart-grid devices. The following fiveareas are referred to as the Open Smart Grid Protocol (OSGP).

• Data exchange with smart-grid devices allows Utility Suppliers to collect customer usage information such as billing data and load profiles, monitor and control grid utilization, provision scheduling of tariffs, detecttheft and tampers, and to issue disconnects, to name a few. Meter features are described in Clauses 7 and8.• The OSGP data interface uses a representation-oriented model (tables and procedures) which require low overhead. The model is described in Clause 5, with specific tables specified in Annex A, Annex B, andprocedures in Annex C and Annex D.• The OSGP application protocol is designed to use the EN 14908-1:2014 communication stack over narrow-band power line channels. Clause 9 describes the messages that are used to access OSGP data. Anessential feature of the protocol over power line channels is a repeating mechanism which gives theapplication layer the control and responsibility for forwarding packets among devices, independent of therouting protocol or limitations of underlying layers. Therefore OSGP can be adapted to othercommunication stacks and medium, although such adaptation is outside of the scope of thisspecification. The repeating mechanism is described in Annex G.• OSGP management features include the discovery of devices and the routing topology in a protocol called Automated Topology Management (described in Clause 4) commissioning of devices for securedcommunication (Annex F), monitoring of device connectivity, and updating of device firmware.• OSGP security covers authentication, encryption, and key management. This is detailed in Annex F.Cross References:ISO 8859-1ECMA-94IEEE 802.11ac:2013ISO 646:1991EN 14908-1:2014IETF RFC 5433:2009NIST 800-38CNIST 800-108IETF RFC 3610:2003NIST 800-38BIETF RFC 2119:1997NIST 800-38DIETF RFC 7539:2015EC 61000-4-7FIPS PUB 197EN 13757-2:2004EN 13757-3:2004ISO 646:1991EN 14908-3:2014
