Abstract

The development of the distributed generation is a world tendency. Consumers of the distributed generation
act as “active” participants at producing electric energy and regulating grid modes when achieving their own
aims. This system requires development and introduction of technologies promoting the interests of all process
participants. This research offers a solution to the task of voltage regulation within the distributed electric grids
under condition of inconsistent interests of power consumers and distribution companies. This solution includes
a system of decentralized multi-agent voltage regulation, which provides trade-off network voltage based on
a uniform practice code for each regulator. This system may be implemented as a special device controlling
power demand – DSM (Demand Side Management).
Experiments were carried out in the Surgut’s small-sized distributed generation. A specially developed
software enabled simulation aimed at minimum real-power losses in adjacent grid regions. Voltage regulation
methods were compared based on results of simulation of typical grid modes with due regard to voltage regulation
peculiarities dependent on the specified load curves. An optimal voltage mode determined with the developed software is close to global optimization. It increases grid power capacity without the need for a total grid observability.
