Research on IEC 61968 Standard Oriented Function Framework of Adapter in Smart Distribution Grid

The ordered and unblocked information flow is an essential characteristic and goal for smart grid whilst the adapter is a key technology for heterogeneous system integration and information exchange. With the rapid development of IEC 61968 and Information Exchange Bus (IEB), the current adapter implementation profile can´t fulfill the requirement of inter-operation in smart distribution grid. This paper illustrates the concept of adapter and its role in information exchange model of IEC 61968 standard, and proposes a six-layer function framework for IEB and heterogeneous systems. In the facet of heterogeneous systems, it proposes the three-layer function framework and implementation profile including adaption for web services, adaptation for business interfaces and adaption for IEC 61968 messages. In the facet of IEC 61968 standard based IEB, it proposes another three-layer function framework and implementation profile consist of adaptation for asynchronous exchange pattern, adaptation for plug & play and adaption for information flow control.
