Cross-domain approach for operation support in smart grid

Power grid operation centres have been separately developed and operated in various domains, such as the transmission, distribution and marketing domains. As the need for cooperation among domains increases in the smart grid environment, operation of the grid based on separated domains reveals serious problems, such as heterogeneous data presentation. For reliable operation of the smart grid, it is essential to integrate data from separated domains in real time and provide seamless analytics without increasing the security risk. This study presents a cross-domain approach to grid operation that supports cross-domain monitoring, seamless analytics and simulation based operation action recommendation. The results of the experiment show that the presented system monitors the whole grid state and supports seamless analytics with acceptable overhead.
