A parallel operation control method for different type power generation apparatuses to shift the power generation apparatuses having respective different drooping characteristics, in which the drooping characteristic is defined as a characteristic of decrease of a rated frequency along with an increase of a load, from independent operation of the power generation apparatuses under suitable drooping characteristics to parallel operation thereof to drive a common drive target, includes determining a load of one of the power generation apparatuses by subtracting a load of the other of the power generation apparatuses from a predetermined required load; changing a drooping characteristic of the one of the power generation apparatuses so as to coincide with a drooping characteristic of the other of the power generation apparatuses; and controlling the one of the power generation apparatuses so as to maintain frequency at the time of changing the drooping characteristic.
A parallel operation control method for different types of power generation apparatuses to shift the plurality of power generation apparatuses that have respective different drooping characteristics, in which the drooping characteristic is defined as a characteristic of decrease of a rated frequency along with an increase of a load, from an independent operation of each of the power generation apparatuses under respective suitable drooping characteristics to the parallel operation of the apparatuses to drive a common drive target, which method comprising:
