Abstract

In the framework of the so-called microgeneration, small photovoltaic units are being installed in the roofs of the buildings and connected to the low-voltage distribution networks. This is posing some new challenges to the distribution network operators. On one hand, the off-service regulation of the transformer taps must comply with a hard twofold objective: to mitigate the undervoltages during peak load periods and to mitigate voltage rise during peak generation periods. On the other hand, the voltage profile is almost insensitive to microgeneration injected reactive power, which forces control to actuate on active power with the consequent impact on energy produced and also on network security. These two aspects of the problem are addressed in this paper with help from an illustrative test network, on which several case-studies have been built to highlight the main voltage control problems and to test different strategies to overcome such problems.
