ESO Reactive Power for Voltage Control pilot project

Decarbonization | Digitalization | Distribution network

ESO is testing new voltage regulation technologies, which would allow to flexibly manage voltage in electricity distribution networks. The tested system automatically regulates voltage in each phase of electricity network separately by using voltage regulators. If necessary, the voltage in the network can be increased or decreased, thus ensuring a seamless operation of consumers’ devices. By performing the pilot project, the company is looking for the most innovative solutions world-wide to apply them in Lithuania.

Currently EcoVAR solution – low voltage static compensator (STATCOM) is being tested. To control voltage it is using reactive power and this device that can improve voltage swells and sags (180-270V operating range). Such solution helps clients with PV installations and voltage quality problems on long overhead lines.
