Importance of environmental efficiency of electric power industry stems from high demand for energy combined with global warming concerns. It is especially essential for the world largest economies like that of the United States. The paper introduces a Data Envelopment Analysis (DEA) model of environmental efficiency using indicators of fossil fuels utilization, emissions rate, and electric pow...

With the increasing electric power demand, power systems can face to stressed conditions, the operation of power system becomes more complex, and power system will become less secure. Moreover, because of restructuring, the problem of power system security has become a matter of concern in deregulated power industry. Better utilization of available power system capacities by Flexible AC Transmi...

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...

The reliability standards for electricity supply in a developing country, like Nigeria, have to be determined on past engineering principles and practice. Because of the high demand of electrical power due to rapid development, industrialization and rural electrification; the economic, social and political climate in which the electric power supply industry now operates should be critically vie...

Growing integration of distributed energy resources (DER) presents the electric power sector with the potential for significant changes to technical operations, business models, and industry structure. New physical components, control and information architecture, markets, and policies are required as the power system transitions from one of centralized generation and passive load to a network ...

INTRODUCTION Occupational fatalities due to contact with electricity account for approximately 9% of all deaths in the construction industry and is the fourth leading cause of death in this industry. METHOD Differences in the proportions of electrocutions in the construction industry are significantly different from other industries based upon the age of the worker and the source of the elect...

The trend, which appears in the development of modern transmission systems, is the more intensive utilization of existing networks. In addition to this, due to deregulation and reconstruction of the electric power industry, the need arises to transport large blocks of power between areas through defined corridors. Further more, the voltage profile of the remote buses of systems is necessary to ...

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...
