Abstract
This paper describes solutions for voltage control in low-voltage distribution networks with a high penetration of decentralized feed-in systems. Electric equipment such as controllable distribution transformers with on-load tap changer (OLTC), reactive-power capable PV inverters and decentralized line voltage controllers were included in the study. After a short description of the issue of voltage control in distribution networks, we will continue with a description of the proposed solutions including the electric equipment and selected system concepts, as well as their advantages and disadvantages. In conclusion, a model of an existing low-voltage network is used to compare the concepts taking into account the potential increases in hosting capacity, losses caused by limiting active power, and the required reactive power that needs to be provided.
