Modern global trends to decentralize power consumers that are associated with increasing cost of traditional fuel and manifested in the increasing proportion of distributed electricity production from distributed energy sources, lead to complications planning regimes of electric power systems and their operational management. In addition, the combination of the mentioned above processes with economic power engineering reform - implementation of bilateral agreements - virtually prevent to organize the effective functioning of the electric power systems without improving their information infrastructure with a gradual transition to the concept of intellectual power networks Smart Grid.
