DETERMINING METHOD FOR LOAD DISPATCHING

PURPOSE:To make it possible to determine a power supply feeder at high speed in load dispatching, by converting one bit in the position of a string, and thereby changing the direction of feeding power supply to only one load to comply with the restrictions of radial system and transport route.

Zusammenfassung:	PURPOSE:To make it possible to determine a power supply feeder at high speed in load dispatching, by converting one bit in the position of a string, and thereby changing the direction of feeding power supply to only one load to comply with the restrictions of radial system and transport route. CONSTITUTION:A genetical algorithm is applied to the determination of a power supply feeder in load dispatching. A radial load is determined for each power supply so that a feeding power supply will be determined for all the loads. The final state of load dispatching is converted into a string expressed in a specified manner to generate an initial string (S1). Then the string is evaluated and subjected to sort-out. Crossing and mutating are performed to manipulate the string (S2, S3). If a string not in conformity with the restrictions of a distribution system is produced as a result of the crossing, the string is corrected taking into account the extra feeding capability of the power supplies to comply with the restrictions. These strings are repeatedly evaluated and manipulated to their final generation to find a quasi-optimum solution for load dispatching.
