Voltage control methods in LV networks with high penetration of dispersed generation

The growing number of distributed energy sources connected to the low voltage network causes changes in the network operation conditions. The proper response to these changes from the distribution system operators is necessary to maintain the required power quality indicators without the need to limit the ability to connect new sources to the network.
The article discusses the negative phenomena observed in LV networks with a large share of distributed generation (DG) and their impact on the voltage profile in the network. The analyzes focus specifically on photovoltaic micro-sources due to their wide use in urban areas. An overview of methods for reducing the negative impact of PV sources on network voltages is presented. Two variants of algorithms for the operation of the voltage control system in the network are also proposed.
