The objective of this invention is to provide an autonomous distributed electric power system without depending on a known electric power system. In order to achieve such objective, this invention proposes a following feature: Output frequencies of autonomous grid-connection inverters (104, 164) are to be variably controlled by the control system depending on a change of a stored electric power amount [kWh] of the direct current electric power storage device (102) within an alternating-current autonomous--distributed electric power system; and, such electric power system is built of plural electric power supplier and demander (11, 12, 13, 14, 15) who have electric power storage devices with a system which can control such inverters (104, 164); those inverters are voltage self--exciting as well. |
