Power IT test-bed system for smart grid

When merging new power IT(PIT) systems, it is necessary to evaluate operating condition in order to verify the efficiency of these systems. To do so, it is required to develop some test tool and test-bed system. In this paper, we propose a design methodology of this test tool. The test tool is concerned about PIT research results such as intelligent transmission system, power telemetrics, K-EMS (Korea-energy management system), digital substation system, intelligent distribution system, and value added service of power system.
