“…In the commercial environment there are also known occurrence of interfering of audio systems by grid connected PWM converters, which are nowadays widely applied in contemporary interruptible power supply system. Levels and spectral content of current distortions injected into electric power grids are tending to increase despite the fact that the acceptable levels are determined by numerous regulations [12], [3], [13], [14], [15], [10], [16], [17], [18]. In recent years many of PWM boost rectifiers of relatively high rated power have been introduced into power grid because of many advantages, like for example: current harmonics limitation, reactive power compensation and bidirectional power flow.…”

Modern AC/DC converters with bidirectional power flow employing PWM boost topology generate harmonic distortions of input current in relatively high frequency range tightly related to modulation carrier frequency. These frequencies and its multiples in typical applications are usually located in frequency range from single up to several of kHz. Increased harmonic emission in this frequency range can easily and harmfully influence sensitive control and measurement systems what occurs more often nowadays in applications where high power AC/DC PWM boost converted are used. This paper presents a comparison of current harmonic emission of PWM boost rectifiers with relation to classic diode rectifiers. New class of electromagnetic compatibility problems arising in power system are underlined as a result of increased harmonic distortions emission in frequency range up to 9 kHz.

Abstract. The changes that have been taking place recently in the power sector, lead to an increasing share of distributed generation (DG) in the electric power production. Many different energy sources can be distinguished in this area and majority of them incorporate power electronic electrical energy converters interfacing with a power system. Connection of a large number of distributed energy sources (DES) changes the power system work conditions both in positive and negative sense. On the one hand, they emit disturbances to electric power network and on the other hand, they can be effective means of the compensation of such disturbances and also can be used to improve the quality of power delivery. Their additional capabilities are performed by power electronic converters.Development of a modular universal interconnection architecture of these converters with standard functions for power conversion, power conditioning and quality, protection, controls, communications, ancillary services, and metering is the cornerstone of streamlined DG interconnection. Similarly, developing standard certification and testing procedures for the interconnection of DG converters, and then deploying and field testing many of the recently commercialised interconnection devices is a needed step in this process.The main goal of this paper is to present the possibilities of application of the power electronic converters coupling DESs with supply networks to perform ancillary services resulting from supply network characteristics.In the first part the interaction between DESs and networks is described and quantified. Then ancillary services are defined, as the new tasks that designers of converter can/should undertake as well as the standardization gap with respect to the converters that perform ancillary services. For the purposes of this paper the converter is considered to be a black box connected to the power system. The paper concerns DESs connected to distribution networks.
