Electric Vehicle (EV) technology is expected to take a major share in the light-vehicle market in the coming decades<em>.</em> Charging of EVs will put an extra burden on the distribution grid and in some cases adjustments will need to be made. On the other hand, EVs have the potential to support the...

The extensive deployment of megawatt-scale wind turbines is bringing more challenges to the safety and stability of electric grid than ever before. This is not only because of the unstable wind over time but the increased risk of power quality pollution by defective wind turbines particularly...

The integration of wind power into national grids introduces a unique set of challenges. The wind-turbine generators are incapable of supplying the voltage and frequency control and they absorb significant amounts of reactive power particularly when there is a fault in the system. The utilities,...

Parallel to growing grid-integrated applications, the power converters have been an important research field for the power conversion and power quality. The converters can be used in different power levels ranging from large adjustable speed drives to low power household applications and office...

The development of distribution networks for participation in active network management (ANM) and smart grids is introduced using the microgrid concept. In recent years, this issue has been researched and implemented by many experts. The second part of this paper describes those developed...

This paper proposes a reduced 2nd, 3rd, 5th and 7th harmonic current of all power supply units and ac drives which effects of heating neutral cables and transformer. The commercial or automation building require the operation of many parallel-connected switch mode power supply and ac drive on...
