A power controller 10 capable of grid interconnection of at least one distributed power source of a first type (31, 32) and at least one distributed power source of a second type (12, 40) together includes: a switch 15 configured to switch between a parallel state in which the at least one distributed power source of the second type (12, 40) is interconnected to a grid together with the at least one distributed power source of the first type (31, 32) and a parallel off state in which the at least one distributed power source of the second type (12, 40) is independent of the at least one distributed power source of the first type (31, 32) and is paralleled off from the grid; and a controller 11 configured to cause the switch 15 to be in the parallel off state when reverse power flow occurs. |
