Network radiality, parameter, and performance heuristics in optimization of power distribution system operations. Part 1: crisp rule base

Part 1 defines network radiality, parameter, and performance heuristics that are employed in a three-level hierarchical rule base for optimization of power distribution system operations. A heuristic preprocessor module produces a list of switch closures that would seem to reduce total system losses. Network radiality rules are employed to assess if a particular search path has identified a switch that can be closed or if the path is worth pursuing further. Network parameter rules ensure the system operates within original design parameters. Network performance rules assess the reduction in total system losses of each proposed switching operation. Part 2 describes the fuzzification of the rule base. This is part of an intelligent optimization system for multiobjective performance optimization of power distribution operations.
