Abstract: The grid interconnection system is provided with a switching unit configured to switch a connection destination of an interconnection terminal of a first power conditioner and a load, between a power grid and a self-standing terminal of a second power conditioner, and a connection controller configured to execute, on the switching unit, first control for connecting the power grid to the interconnection terminal of the first power conditioner and the load in a non-power outage of the power grid, and second control for connecting the self-standing terminal of the second power conditioner to the interconnection terminal of the first power conditioner and the load in a power outage of the power grid.

Abstract: In a power conditioner, a DC-DC converter outputs an output of a first power source for which reverse power flow is permitted to a DC supply line, and a bidirectional DC-DC converter discharges an output of a second power source for which reverse power flow is not permitted to the DC supply line and, on the other hand, charges power of the DC supply line to the second power source. A DC-AC inverter converts DC power of the DC supply line to AC power and outputs the converted power to outside. When a power consumption of a load exceeds a rated output of the DC-AC inverter and a power generation amount of the first power source exceeds the rated output of the DC-AC inverter, a portion of surplus power of the first power source is charged to the second power source.
