The increasing number of renewable generators, in particular photovoltaic systems in the low voltage networks of rural areas, causes a strong increase of the power flows. As of today, in meshed grids the power flow is not controlled and the thermal limits of cables can be reached or exceeded. As a consequence failures may occur. With the help of phase shifting regulators for low-voltage distribution grids the power flow in a meshed grid can be controlled and thermal overstress can be prevented to a certain extent. A new type of equipment is proposed which can regulate the power flow by applying a control voltage at a certain angle. In this paper, the methods for calculating the control voltage and a design concept for the regulator are presented.
