Abstract: This application discloses a method for implementing a fast power response and a power plant. The method is applied to a power plant-end power control apparatus, and includes determining a whole-plant reactive power target value and/or a whole-plant active power target value of the power plant. The method also includes determining, based on the whole-plant reactive power target value and/or the whole-plant active power target value, a second power control instruction readable to each photovoltaic inverter or power conversion system in the power plant. The method further includes delivering, through a subarray controller or a subarray communication device over an Ethernet network and/or a field bus network, the second power control instruction to each photovoltaic inverter or power conversion system indicated by address identifier information carried in the second power control instruction, so that each photovoltaic inverter or power conversion system makes a fast power response based on the second power control instruction.
