A Preliminary Communication Model of Smart Meter Based on IEC 61850

There will be quite a large amount of smart meters used in AMI, which may be produced by many different manufacturers. Therefore, it´s very important to maintain interoperability among different devices, and reduce or even avoid the overhead of protocol conversion. Using a general standard might be a very good way to accomplish interoperability. This paper attempts to use IEC 61850, which will be the seamless standard in power system, for smart meters to achieve interoperability. Information model and information exchange model, which are called jointly the communication model, are constructed based on the standard. The construction of communication model is the key cornerstone of realizing interoperability in smart meters.
