Title: Loss and Cost Minimization with Enhancement of Voltage Profile of Distribution Systems Using a Modified Differential Evolution Technique
Abstract: Distribution system is one of the important parts of power transfer systems. Large amount of power losses take place in the distribution system. Many modern heuristic techniques have been successfully applied over the years to solve the problem. Satisfactory performance of evolutionary algorithms like differential evolution is highly dependent on the setting of control parameters. One of the major difficulties for them is the selection of parameters which usually depend on specific problem under consideration. Sometimes, wrongly selected parameters may lead to premature convergence or even stagnation. It has been found that self-adaptation is a viable alternative option in setting control parameters. In this paper, a new hybrid optimization algorithm based on differential evolution and chaos theory called logistic map differential evolution (LMDE) is presented for minimization of loss and cost of distribution networks. Enhancement of voltage profile is also considered. The motivation behind the present work is to get rid of early convergence. To validate and demonstrate the effectiveness of the proposed method, a sample test system is considered. The simulation results clearly show that it can successfully avoid premature convergence. A comparison result is also presented which shows the capability of the proposed technique.
