Minimization of Power Losses in Distribution System via Sequential Placement of Distributed Generation and Charging Station

Abstract

Energy saving in a distribution system through minimization of power losses is a crucial task for cost-effective operation. One of the most effective approaches in minimizing losses is through the application of distributed generation (DG). To achieve minimum losses, the correct size of DG could be determined using various optimization techniques. Different from other approaches, this paper presents an alternative method to minimize losses through optimal size of DG and optimal location of charging station (CS), which overall reduces the power losses of the network. This paper also investigates the impact of constant voltage (PV) or constant power (PQ) mode of DG to the overall power losses with the aim of choosing the best mode. The suitable DG operation modes and proper sequential placement between DG and CS does not only reduce the power losses, it has also opened new possibilities to add new additional loads in the system. The algorithm's performance shows promising results in minimizing power losses when tested using 33 bus radial distribution networks.
