FIELD: electricity.;SUBSTANCE: invention is related to electric engineering and can be used to operate at joint centres of electric power consumption for instance for large municipal areas or geographical regions. In the method and the device for improvement of alternating currant power transmission system dispatching capabilities, electric power transmission system provides isolation of local alternating currant power supply system from surrounding alternating current system, and local centre of alternating current power consumption has multiple local alternating current loads and distributing system feeding line that supplies multiple local alternating current loads. Additionally there is at least one remote power station or other electric power source to deliver alternating current electric power to local centre of alternating current power consumption. To isolate alternating current electric power received from remote power station from local centre of alternating current power consumption by converting alternating current electric power into direct current electric power, full or partial ring of direct current power lines are created between local centre of alternating current power consumption and remote power station. Then the second conversion of direct current electric power into alternating direct current electric power is performed on the basis of demands in electric load. Feeding line of distributing system delivers alternating current electric power from remote power station providing isolation of all local alternating current loads.;EFFECT: providing stability of alternating current - direct current - alternating current power supply with simultaneous power flow control in all incoming and outgoing power lines carrying alternating and/or direct current.;23 cl, 4 dwg
