Electrical power supply system, moving object, and method of controlling electrical power supply system

An electrical power supply system, comprising:

• a first electrical power generating device configured to output a three-phase alternating current electrical power;
• a second electrical power generating device configured to output a three-phase alternating current electrical power;
• a first electrical power conversion device including a smoothing capacitor, and configured to convert the three-phase alternating current electrical power output from the first electrical power generating device into a direct current electrical power;
• a second electrical power conversion device including a smoothing capacitor, and configured to convert the three-phase alternating current electrical power output from the second electrical power generating device into a direct current electrical power;
• a first electrical power supply circuit configured to supply the direct current electrical power output from the first electrical power conversion device to a first load device;
• a second electrical power supply circuit configured to supply the direct current electrical power output from the second electrical power conversion device to a second load device;
• a first electrical power storage device configured to be connected to the first electrical power supply circuit in parallel with the first electrical power generating device;
• a second electrical power storage device configured to be connected to the second electrical power supply circuit in parallel with the second electrical power generating device;
• a first connection circuit equipped with a first connection device configured to connect the first electrical power supply circuit and the second electrical power supply circuit;
• and
• a control device configured to execute, on the first connection device, a first connection control that causes the first electrical power supply circuit and the second electrical power supply circuit to be connected,
• wherein the control device comprises one or more processors that execute computer-executable instructions stored in a memory, and
• wherein, in a case of supplying the direct current electrical power output from the second electrical power conversion device to the first load device, a first electrical power reduction control that causes the direct current electrical power output from the second electrical power conversion device to be reduced is executed on the second electrical power conversion device, and thereafter, the one or more processors execute the computer-executable instructions to cause the control device to execute the first connection control on the first connection device.
