Active intelligent distribution networks - coordinated voltage regulation methods for networks with high share of decentralised generation

This paper describes several voltage regulation approaches and strategies for distribution networks for achieving a cost-effective integration of high shares of distributed generation by an optimal utilization of already available network capacities. The voltage regulation methods are examined by their theoretical potential using an approach with generic networks in a first step. Afterwards case studies for their application in a real rural low voltage (LV) network with different scenarios for the installation of new photovoltaic (PV)-systems are carried out. Information about the pilot test phase applying these voltage regulations methods is provided as outlook.
