Voltage quality in urban and rural areas

The number of power distribution user networks feeding energy efficient equipment is growing. The situation is becoming even more complex with the introduction of distributed generation. The network connects non-linear electronic loads, as well as sources. We investigated the effect of such a source, a photovoltaic converter on the voltage quality. These results have been listed and compared to measurements which have been performed at many places. In some areas, several major low power quality events have been observed, such as outage. Furthermore, it is shown that modern electronic equipment contributes to an increased pollution of the voltage, i.e. decreased voltage power quality.
