Abstract

The Distribution Companies (DisCOs) are continually trying to supply reliable and economical electric power to consumers. The design, operation and maintenance of the DisCOs are framed on the lowest cost and for the highest benefit. The voltage profile enhancement and power loss reduction are two important tasks in the DisCOs for achieving maximum profit.  Many technical ideas and creative programs are being developed by the DisCOs anyhow to improve the performance. In this paper, an innovative approach of Ant Lion Optimizer (ALO) is projected for maximizing the DG owner’s profit and minimizing the Distribution Company’s cost. The proposed soft computing method is efficiently optimizing the size and optimal location of DG with standard operating constraints to increase the voltage profile and reduce the network loss of DisCOs. The uncertainty of load demand, power generation, electricity price and reliability are considered in this work. The validation of this method is tested on standard IEEE 33 node system to illustrate the superior performance of ALO algorithm. The simulation results of voltage profile, power loss, location and size of DG, cost-benefit of DisCOs and DG owners are numerically and graphically presented in this work. The comparative study also has been made to prove success of the devised method.
