A knowledge-based method for making restoration plan of bulk power system

A method is proposed for use in the event of power system outages which uses general-purpose restoration knowledge not dependent on preoutage system states to generate postrestoration target systems in which postoutage systems are taken as initial states. A method is proposed by which system operations in both blackout systems and sound systems are combined according to the amount of load in the preoutage systems, so that postrestoration system states with minimal outage loads from postoutage systems will be generated. A prototype system incorporating actual power systems and utilizing this method was built and tested under simulated conditions. The effectiveness of the proposed system is discussed on the basis of the test results
