Abstract: The key factor for voltage stability of a distribution system is one among the most interesting areas of industry and research sectors far and wide. It considered the steady load activity and permissible voltage limits all over the network nodes. Of this, the capacitor is equipped for providing reactive power in the network which effects of limiting the power misfortunes and improves the voltage profile and stability of the system. In this paper, net saving maximization is consider as a target and as speaking to an expense of energy loss, installation, purchase and operating costs of capacitors. It is solved by using an Ant Lion Optimizer (ALO) algorithm. The ALO is to actualize the issue in order to maximize the objective of problem formulation. The fixed and switched type capacitors have used in this approach. The prevalence of the presented method is veteran on 34-node and 69-node systems. The assessment results of this approach are compared with the existing report.
Keywords: Radial distribution system, Voltage stability, Capacitors, Net cost savings, Power loss and Ant line optimizer.
