Interoperability is the unquestioned condition for building future smart metering systems and the smart grid.
Likewise, the availability of open standards is the unquestioned condition for achieving interoperability.
That’s why the European Commission in its Mandate M/441 requests the European Standardisation organisations CEN, CENELEC and ETSI to develop European standards within an interoperable framework specifying an open architecture, additional functionalities as well as data exchange formats and protocols.
That’s why the European OPEN meter project – an invited partner of the ESOs in carrying out the mandated standardisation work – has also set the objective to develop specifications for smart metering agreed on and supported by all major stakeholders that will form the basis of the European standards.
That’s why the US congress requests the development of a Smart Grid Interoperability Framework and charged the National Institute of Standards and Technology with the development.
That’s why the IEC SMB (Standardization Management Board) has set up a Strategic Group SG 3 taking charge of global interoperability in setting international standards for the smart grid.
Through its members, the DLMS UA is actively participating in all major smart metering standardisation efforts.
The IEC 62056/EN 13757–1 DLMS/COSEM specification, with recent additions for smart metering, has been identified both in the OPEN meter project and the EU SM-CG as one of the core standards for the smart metering standard suite.
The DLMS UA is also taking actions to raise interoperability to a new level. Earlier this year, the setting up of a new working group, Final End Users and Developers, has been initiated and approved. The objectives of this WG – led by EDF – are the development of use cases, providing feedback from the development and field experience to the standardisation process, interoperability testing, and in general improving information exchange within the user community of DLMS/COSEM.
The Interoperable Device Interface Specifications (IDIS) initiative, announced in September by Iskraemeco, Itron and Landis+Gyr, also aims at improving interoperability by developing specifications, strictly based on DLMS/COSEM, specifying all necessary choices and details necessary to implement selected function sets in a fully interoperable way. These specifications will be validated by the DLMS UA and will be made available for the more than 150 members of the DLMS UA.
