PROBLEM TO BE SOLVED: To allow inverse load flow from a dispersion type power source to a commercial power circuit, and to continue power supply in uninterruptible manner when the commercial power circuit fails.SOLUTION: A power feeding system includes a power generation device, a power conditioner which converts a generated power from the power generation device to a predetermined AC power, an AC switch which connects between a commercial power circuit and a load and cuts off between the commercial power circuit and the load in a case the commercial power circuit fails, a storage battery for accumulating a power that is fed to a load, a bidirectional conversion device which performs bidirectional conversion between AC power and DC power, between a load side of the AC switch and the storage battery, a route switching part which selects any one of a first route of a stream to a load side of the AC switch through the power conditioner and a second route of a stream to the commercial power system side of the AC switch through the power conditioner, as a route for the generated power of the power generation device to flow, and a control part which controls the route switching part to switch a route through which the generated power of the power generation device flows. |
