Thnk of it as an Intelligent operator.In Power systems Operators isolate the faulty section and restore the power to good section via other feasibile routes .Now doing all this thru computers does not appear to be a task out of our current knowldge base. What it does require is the kowledge of the feasibile routes and verifying their status. The problem arises when we need to cut the faulty section of a feeder and link the good section to another feeder nearby thru a tie line connected to some point on this feeder.This requires Online simulation of the feeder to which the good section is to be connected as well as the load and voltage scenario after the connection.However the problen can be simplified of the entire load of the good section can be transferred to the new feeder. In case there is very good knowledge of the loads the system could work as a self healing grid with propoer automation.One way to make the system hold is to design feeders thru an area in such a way that there is always such an availability.Thus Self healing grid will require standardization of the grid and feeders design to be a reality
