In the future, the zone of decentralized power supply of the Republic of Sakha (Yakutia) will remain due to the large distances between settlements and weak transport infrastructure. The voltage of 6-10 kV and 0.4 kV distribution networks is highly susceptible to distorting loads caused by the widespread use of converters and electric motors. Consumers will be provided with electricity from local low-power energy sources, mainly diesel power plants using distributed generation, including renewable energy sources, which will further worsen the performance of electrical energy in distribution networks due to fluctuations in the parameters of these sources. Therefore, it is necessary to create and introduce new types of devices in distribution networks. For a comprehensive solution to the problem of reactive power compensation (voltage stabilization), balancing and dynamic filtering of voltage in distribution networks, a new technical solution is proposed based on a thyristor stabilizer of parameters.
