Introduction of new technologies such as energy storage systems, electric vehicles, and distributed generation improved the characteristics of networks. On other hand, using these components in distribution systems improves system performances such as power losses. One of effective methods for improving system characteristics is distribution network reconfiguration. In this study, in addition t...

Increased electric energy consumption in recent years, associated economic problems, reduced reliability and increased power losses in electric networks. One of the main solutions in smart grids to overcome the mentioned problems is demand response programs. In demand response programs, operators apply time-varying tariffs to consumers, and convince them to change their consumption pattern. Amo...

There are numerous advantages of using Electric Vehicles (EVs) as an alternative method of transportation but an increase in EV usage in the existing residential distribution grid poses problems such as overloading the existing infrastructure. In this paper, we have modeled and simulated a residential distribution grid in GridLAB-D (an open-source software tool used to model, simulate, and anal...

Introduction: Public and occupational exposure to extremely low frequency (ELF) electric and magnetic fields induced by electrical equipment is a significant issue in the environment and at the workplace due to their potential health effects on public health. The purpose of this study was assessment of the electric and magnetic fields intensities and determination of mental and psychological ef...

This paper presents a lifetime efficiency index model and a developed crow search algorithm (DCSA) in order to achieve optimal maintenance for the power transformer. Not doing maintenance on the power transformer, resulting in instability of the transmission system and not to supply consistently electric energy in the load points. In other words, deterioration of the transmission system effects...

M. Moallem and A. Kiyoumarsi,

The rapid increase of non-linear loads in the last three decades has caused electrical quantities such as voltages and currents in 3-phase distribution systems to become distorted waveforms. This paper reviews, explains and discusses some new concepts, definitions and new available theory in the unbalanced and distorted systems. The usefulness of the proposed practical definitions is investigat...
