Recent development of the smart grid significantly enhanced the level of automation in the distribution grids. With a higher level deployment of remote-controlled switches, distribution feeders can be restored more efficiently after power outages. In this presentation, computational algorithms for feeder restoration will be discussed together with their practical implementations. The role of microgrids in distribution system restoration will be evaluated. The traditional techniques, however, are not designed for extreme events in the distribution systems. The same is true for widely adopted reliability indices. New thinking of the system design and operation will be important.
