Control method of power generation system, power generation system, and power generation apparatus

A control method of a power generation system configured with a power generation apparatus and at least one other power generation apparatus coupled to the power generation apparatus, the power generation system configured to interconnect with a grid and supply power to a load, wherein the control method includes:

• a step of obtaining a sensor signal from a current sensor configured to detect a current flowing between the grid and the power generation system by the power generation apparatus,
• an output step of outputting the obtained sensor signal to the other power generation apparatus by the power generation apparatus,
• a first control step of, based on the sensor signal, controlling to reduce an output of power generated by the power generation apparatus, and
• a second control step of, based on the sensor signal output from the power generation apparatus, controlling to reduce an output of power generated by the other power generation apparatus.

A power generation system comprising:

• a power generation apparatus;
• and
• at least one other power generation apparatus coupled to the power generation apparatus, the power generation system configured to interconnect with a grid and supply power to a load, wherein
• the power generation apparatus includes a controller that determines, based on a current detected by a current sensor between the power generation system and the grid, target power to be generated by the power generation apparatus and the other power generation apparatus and notifies the other power generation apparatus of the target power.

A power generation system comprising:

• a power generation apparatus;
• and
• at least one other power generation apparatus coupled to the power generation apparatus, the power generation system configured to interconnect with a grid and supply power to a load,
• wherein the power generation apparatus is configured to obtain a sensor signal from a current sensor configured to detect a current flowing between the grid and the power generation system and output the obtained sensor signal to the other power generation apparatus via a communicator, and includes a first controller configured to control, based on the sensor signal, to reduce an output of power generated by the power generation apparatus, and
• the other power generation apparatus includes a second controller configured to control, based on the sensor signal output from the power generation apparatus, to reduce an output of power generated by the other power generation apparatus.

A power generation apparatus coupled to at least one other power generation apparatus, the power generation apparatus configured to interconnect with a grid and supply power to a load, including

• a power generator configured to interconnect with the grid and generate power supplied to the load, and
• a controller configured to control an output of power generated by the power generator,
• wherein the controller is configured to receive a sensor signal from a current sensor configured to detect the current flowing between the grid, and the power generation apparatus and the other power generation apparatus, and is configured to output the sensor signal
• to the other power generation apparatus, and
• wherein the controller, based on the sensor signal controls to reduce the output of the power generated by the power generator.
