Abstract
The intermediate step in the transport of electrical power from the central producing plant to the customers is
the electric transmission system. One of the most important goals for any electric utility is to minimize active
power losses since it is crucial for improving system characteristics in order to handle higher load requirements
and minimize production costs. Because there is not enough reactive power in the network, the voltage at buses
decreases and loss rises. The shunt capacitor banks provide the necessary reactive power. The best location for
capacitors in the transmission system has long been researched. The goal of this optimization issue is to
determine the best capacitor sizes and placements. In this paper, we have investigated the possibility of
lowering the value of real power losses for global system transmission lines by employing a genetic algorithm
to determine the optimal location and sizing of shunt capacitors while taking into account the value of real
power losses with reactive power injection as a measure of the capacity to lower losses at load buses. The IEEE
6-bus system is used to test the findings.
