A knowledge-based approach for network radiality in distribution system reconfiguration

A knowledge-based system is defined that ensures network radiality during reconfiguration of a power distribution system. Network radiality heuristics identify a pair of switching operations that preserves radiality. A matrix-structured knowledge base with five distinct rule bases is used. Rule base A is used in determining which other rule bases to activate. Rule base B is used in considering whether to open a switch and rule base C is used in finding a corresponding initially open switch to close to assume the load transfer that would be necessitated by the switch opening. Rule base D is used in considering whether to close a switch and rule base E is used in finding a corresponding initially closed switch to open because of the load transfer that would be necessitated by the switch closing. In the interest of brevity, only rule bases A, D, and E are described
