Conclusions
The change of the electricity supply towards distributed generation requires
new quality criteria, new test and certification proceduresnew standards
DER laboratories may play a significant role in the preparation of new standards and requirements for DER
Extensive information exchange and collaborative research between labs is required
The chance of close international co-operationbetween DER laboratories at an early stage is to get a common understanding of the standardisationrequirements for an efficient future power supply’s systems technology.
