Integration of distributed energy sources with electrical power grid

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.
