Network reconfiguration for loss reduction in electrical distribution system using genetic algorithm

Abstract EN

Distribution system is critical links between the utility and the nuclear installation.

During feeding electricity to that installation there are power losses.

The quality of the network depends on the reduction of these losses.

Distribution system which feeds the nuclear installation must have a higher quality power.

For example, in Inshas site , electrical power is supplied to the nuclear reactor and other nuclear facilities from two incoming feeders (one from new abu–zabal substation and the other from old abu–zabal substation).

Each feeder is designed to carry the full load, while the operator preferred to connect with a new abu–zabal substation, which has a good power quality.

Bad power quality affects directly the nuclear reactor and has a negative impact on the installed sensitive equipment and instruments of the operation.This paper introduces an optimization technique based on genetic algorithms for distribution network reconfiguration to reduce the network losses to minimum.

Simulated results are drawn to show the accuracy of the technique.
