Communication-control concept in distribution network with dispersed energy resources

This paper describes a communication concept in distribution network with dispersed energy resources (DER), which regulates and controls voltage profile in the power network. The communication concept is based on fast links between checkpoints on power lines and on DER. Advantage of this concept is establishing communication among all DER, main power lines and control center, which allows them to communicate with each other at any given time without any restrictions. Another advantage of the proposed communication concept involves possibility of upgrading to the existing standard IEC 61850.
