Abstract
This paper focuses on voltage control strategies applied in active, intelligent low voltage (LV) networks. The aim of these advanced methods is the realisation of a cost-effective integration of high shares of distributed generation by an optimal utilisation of already available network capacities. Newly developed components (a MV/LV transformer with OLTC, adjustable PV-inverters and an intelligent control unit of the LV network) required for this active, intelligent LV network are described. The components are integrated in a rural LV network with an already high penetration of PV. Different system concepts and operating modes will be tested within this setup. First results are shown and discussed.
