1. A power generation device comprising:
a first generator connected to a prime mover and configured to output a first alternating current;
a second generator connected to the prime mover and configured to output a second alternating current;
a first DC-DC converter connected to the first generator; and
a second DC-DC converter connected to the second generator;
a first AC-DC converter connected between the first generator and the first DC-DC converter and configured to convert the first alternating current into a first direct current;
a second AC-DC converter connected between the second generator and the second DC-DC converter and configured to convert the second alternating current into a second direct current;
a first inverter connected to a first connection path between the first AC-DC converter and the first DC-DC converter, the first inverter being configured to convert the first direct current into a third alternating current, and to output electric power from the first connection path to a first external power system;
a second inverter connected to a second connection path between the second AC-DC converter and the second DC-DC converter, the second inverter being configured to convert the second direct current into a fourth alternating current, and to output electric power from the second connection path to a second external power system; and
a storage battery connected to an output terminal of the first DC-DC converter and connected to an output terminal of the second DC-DC converter, wherein
an output terminal of the first AC-DC converter is connected in parallel with the first external power system and the storage battery, and
an output terminal of the second AC-DC converter is connected in parallel with the second external power system and the storage battery.
