Study of the Impact on the Rectifying Devices Operation on the Power Consumers in Smart Grid

The issue of power quality in distribution networks is urgent for Russia and this situation is first of all caused by high harmonics. The introduction of semiconductor technology has led to the development and growth of modern high-tech electrical equipment with non-linear current-voltage characteristics. The operation of this electrical equipment is accompanied by a negative influence on the quality of the electrical energy that brings damages. There is a tendency toward increase in the nonlinear load. High harmonics in the supply network considerably decrease the efficiency of both network equipment and electric energy consumers. Deterioration in power quality on the whole increases losses in power supply system. Since in Russia financial settlements between electricity suppliers and consumers take into account only active power, the consumers that generate high harmonics are not interested in their reduction. Hence, the problem of reducing high harmonics is a topical problem particularly in Russia. In this paper the authors consider the methods of mitigating the negative impact of ripples on direct current consumers.
