Changing network conditions due to distributed generation - systematic review and analysis of their impacts on protection, control and communication systems

The development of distributed generation in power systems causes manifold changes due to the network performance and system behavior. Until now numerous papers are dealing with this topic, but considering only partial aspects of these issues. A systematical approach which is particularly necessary in nowadays complex networks and a coherent analysis of impacts is still missing. This present paper is pointing out a proper approach getting holistic results for this matter. Hence a systematical review on the general impacts of DGs on power systems will be presented. Based on that, this paper is analyzing and discussing exemplary impacts on protection, control and communication systems.
