Controlling voltage profile in smart grids with remotely controlled switches

An algorithm for controlling the voltage profile in a power distribution network with dispersed energy resources (DER) is described. The algorithm is based on predictions and fast communication links between the feeders remotely controlled switches, power lines, substations, end users and DERs. The advantages of using the algorithm are in establishing a reliable power distribution network, with a proper voltage profile, appropriate communications and strong interdependences between the components of the power distribution network. A special benefit of this concept is the possibility of having it included in the existing IEC61850 standard.
