Abstract :
Solid state transformer (SST) is a bi-directional electricity exchange device that is proposed to accommodate widespread Distributed Energy Resources (DERs) and Distributed Energy Storages (DESs) into the existing distribution systems. IEC 61850 is the leading standard for power system communications and affords the integration of devices of different types into the system. It is important to have models of all devices which are used in distribution networks. It is obvious that SST has to be modeled with IEC 61850 in order to support its incorporation with DERs and DESs to the distribution system. In this paper a model of a SST and its mapping to IEC 61850 is presented. Existing logical nodes and their use are considered and a new logical node is also introduced.
