Abstract
The voltage profile in a transmission line system should be in the tolerance of the lower limit to the upper limit value. Moreover, the power loss during transmission process should be minimized to increase the lifespan of the transmission lines. The poor voltage profile and high power losses are the results of increasing of power demand due to the arising of electrical energy consumptions. These problems can be solved by using the shunt capacitor bank placements. The installation of capacitors required three specifications which are the locations, size and number of capacitors to improve the voltage profile of overall system. However, these three specifications are difficult to be determined. The best locations for capacitor placements will result in minimum number and size. In this study, the specifications of capacitor placements in transmission networks is determined by using power loss indication and the number and the size of capacitor is based on voltage increment algorithms. The proposed methods will be applied on three transmission networks which are 6-bus system, 14-bus system and 30-bus system using Power World Simulator. The results show that the proposed method able to improve the overall voltage profile and reducing the power loss with minimum number of capacitor placement in the transmission networks.
