Examination of ELCOM-90, TASE.1, and ICCP/TASE.2 for inter-control center communication

The electric power community is striving to achieve uniform and standardized inter-control center communication. Such communication would make it possible to interact and exchange data more easily between control centers, reduce communication related costs, and simplify integration of new equipment and applications. Two major concepts are present in the field: ELCOM and ICCP. These concepts together with their proposed standards, TASE.1 and TASE.2, are examined in this paper. The treatment is focused on the protocol profiles and the functionality and operation of the concepts. Also, issues related to migration and acceptance are dealt with. Knowledge in pros and cons of these issues should support and guide a potential user in choosing an inter-control center communication concept.
