Power electronics interfaces for low voltage distribution generation — EMC issues

In recent years there is observed an intensive growth of activities in matter of bidirectional electrical energy distribution systems. In situation of fast industrial progress the Electrical Power System (EPS) has to be developed to meet energy demand. This development in accordance to new environmental requirements [1] should be managed very cleaver. Because of these the participation of small renewable and clean energy sources in over all Energy Mix is still growing and is restricted by national and international legislations [2, 3]. These small electrical energy sources dispersed in EPS called as Distributed Generation (DG) are the one of most significant part of the future grids — Smart Grids [4]. Although many issues have been widely discussed and solved [5–6] the number of tasks for consideration has not been reduced. This paper introduces some investigation results of DG interfacing with Low Voltage Distribution System (LVDS) using Power Electronics Interfaces (PEI). The EMC phenomena generated by power electronics inverters has been especially considered.
