Disributed automation for back-feed network power restoration

SMART Grid refers to electric power systems that enhance grid reliability and efficiency by automatically anticipating and responding to system disturbances. To achieve smart grid at the power distribution system level, various automatic technologies have been attempted in the areas of system metering, protection, and control. Within these technologies, automated power restoration is an important part of the Smart Grid puzzle. This paper presents an on-line method for the automated power restoration application previously described. The developed method conducts an analysis to achieve back-feed power restoration, i.e., healthy load zones that have lost power will be restored through their boundary tie switching devices from neighboring sources, and no reconfiguration beyond the tie devices will be considered. The back-feed restoration should not overload any part of the back-feeding network.
