The electronic power transformer (EPT) raises concerns for its notable size and volume reduction compared with traditional line frequency transformers. Medium frequency transformers (MFTs) are important components in high voltage and high power energy conversion systems such as EPTs. High voltage and high power make the reliable insulation design of MFT more difficult. In this paper, the influe...

This study presents a comprehensive review of the potential technical impacts of plug-in hybrid electric vehicles on power distribution and transmission systems. This review also presents various power quality impacts on the power system in several aspects. This review conveys a detailed analysis of electric vehicle charging strategies on electrical distribution networks. The two charging aspec...

The continued increase of gas prices and concerns on greenhouse gas emissions in recent years have led to the steadily increasing acceptance of electric vehicles (EVs), especially the plug-in hybrid electric vehicles (PHEVs), by consumers. It seems that PHEVs are poised to become a serious contender for a noticeable share of the car market in the near future. As PHEV draws power through power e...

When large capacity distributed generation including photovoltaic (PV) systems are installed in power systems, reverse power flow from PV systems may cause problem of surplus electric power. To reduce the reverse power flow without the reduction of PV power generation, energy management of customer equipment such as electric water heater is one of the solutions. Therefore, cooperative control o...

The widespread use of Power Electronics based equipment has produced a significant impact on quality of electric power supply. Conventional power quality mitigation equipment is providing to be inadequate for an increasing number of applications. One modern and very promising solution that deals with both load current and supply voltage imperfections is the Unified Power Quality Conditioner (UP...

Are required, but the resultant improved system reliability is often worth the price.advantages of the radial system in figure 2 but also gives greater reliability since the. The radial systems shown in figures 5-2 and 5-3 can be expanded by the. The loop system arrangement is one of several arrangements that can allow one. Typical equipment for this arrangement is low voltage power circuit-bre...

regarding the nature of non-linear discrete placement, and in order to determine the optimal capacity of the substation, the goal in the present study will be a number of local optimum points. in this research, the problem of optimal placement posts to reduce power losses by considering distributed generation (dg). in formulating the objective function, geographical distribution density in the ...
