Cover photo: The severity of global environment related issues is intensifying. Consequently, there is an urgent need for applications of natural energy such as wind power and solar energy, the utilization of hydrogen energy by using fuel cells or the like, the efficiency transport and supply of energy to areas of demand, non-wasteful utilization of energy that has been supplied, and other meas...

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...

many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...

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 ...

In line with the pressures of energy shortage and economic development, Chinese government has adopted a series of measures and policies to promote the exploitation and utilization efficiency of electric power. China is urgently reconsidering its electric power development level and coordinating between power supply and demand sides. Therefore, in this paper, Chinese industrial structure of ele...

Using electric vehicles, in addition to decreasing the environmental concerns, can play an important role in decreasing the peak and filling the off-peaks of the daily load characteristics. In other words, in smart grids' infrastructure, the load characteristics can be improved by scheduling the charge and discharge process of electric vehicles. In smart grids, the customers are instantaneously...
