Abstract
A computer algorithm for optimal voltage regulation using voltage stabilizers is presented. The applied voltage stabilizers are suitable for operation with radial distribution networks, taking into account various load models. The proposed algorithm makes the initial selection, installation, and adjustment of voltage stabilizers, which provide smooth voltage regulation throughout the network, using the existing algorithms, which are appropriately modified and optimized. The algorithm is fast, efficient, and reliable, which is confirmed by its practical application in distribution networks.
Highlights
The high degree of branching of low-voltage electrical networks, an excessive number of connections, and uneven loading of power lines have a significant impact on the voltage level and can lead to instability of the power system
The correct location of voltage stabilizer has a significant impact on its operation in distribution networks
Voltage stabilizers have a significant impact on voltage level of low-voltage distribution networks, and, as a result, cause changes in load current, which leads to a change in electricity losses in the network
Summary
Voltage stabilizer is one of the most effective voltage regulation devices in distribution networks [1,2]. The correct location of voltage stabilizer has a significant impact on its operation in distribution networks. The arrangement of voltage stabilizers in distribution networks has been studied for a long time, but some considerations have not yet been discussed. Voltage stabilizers have a significant impact on voltage level of low-voltage distribution networks, and, as a result, cause changes in load current, which leads to a change in electricity losses in the network. The load model can have an impact on the location of voltage regulators and the choice of their parameters. When modelling a low voltage distribution network, all loads are divided into constant resistance, constant power, constant current, and generalized typical load [4,5]
