Integration of distributed energy resources in distribution power systems

The chapter deals with issues and countermeasures concerning the integration of distributed energy resources (DERs) in distribution power systems. The use of information and communication technologies (ICT) in the integration of DERs is illustrated by using the example of a multiagent system (MAS) approach for the Volt-VAR control (VVC) on the basis of the information provided by phasor measurement units. The analysis of the performances of the MAS approach is carried out by means of a specifically developed ICT-power cosimulation platform that accurately represents the transient phenomena in the power distribution system and the behavior of the communication network.
