PROBLEM TO BE SOLVED: To provide a natural energy power generation system capable of suppressing voltage fluctuation at an interconnection point due to reactive power loss on an interconnection transformer, and a reactive power controller and a control method of natural energy power generation system.SOLUTION: The natural energy power generation system includes: a power generation unit 12 that receives natural energy to generate the electric power; an electric power converter 13 that is electrically connected to the power generation unit 12 and an electric power system 4; an interconnection transformer 2 that is disposed between the electric power converter 13 and the electric power system 4; and a reactive power controller 16 that generates a reactive power command for outputting from the electric power converter 13. The reactive power controller 16 determines the reactive power command so that the sum of a fluctuation component due to effective electric power in the interconnection point voltage between the electric power converter 13 and the electric power system 4 and a fluctuation component due to reactive power in the interconnection point voltage is generally constant.SELECTED DRAWING: Figure 2
