Abstract:
The present invention relates to a method and an apparatus for controlling active power of a wind power generation complex. More specifically, the method and the apparatus for controlling active power of the wind power generation complex can efficiently control the active power at a conjunction point of a power system of a wind power generation installation, which is connected to the power system and comprises multiple wind power generators and an energy storage device. According to the present invention, the method can increase the lifetime of an individual wind power generator by reducing mechanical stress due to excessive output change of the individual wind power generator and efficiently perform an effective power control at the conjunction point of the power system and the wind power generation complex at the same time.

Abstract:
PURPOSE: An integrated output control device for an output control system of a wind power generation plant and a control method thereof are provided to detect a sudden output variation, to independently control a long-term or short-term energy storage device from an individual aerogenerator, and to control a diesel generator and a dump load, thereby stably controlling the output of a wind power generation plant overall. CONSTITUTION: An output control system (110) of a wind power generation plant includes energy storage devices (115,116) which store or discharge the energy generated by aerogenerators included in the wind power generation plant; a diesel generator (118) which operates if the amount of energy in the energy storage devices is not sufficient; a dump load (117) which discharges the excessively generated energy exceeding the capacity of the energy storage devices; a supervisory computing and data acquisition (SCADA) system (111) which individually controls each aerogenerator; and an integrated output control device (200) which senses the output variation of the aerogenerators connected to an electric power system and controls the operation of the energy storage devices, the diesel generator, and the dump load. The integrated output control device controls the absorption or discharge of energy to or from the energy storage devices to primarily compensate the output variation of the aerogenerators. The SCADA system controls the aerogenerators to increase or decrease the output to secondarily compensate the output variation of the aerogenerators. The operation of the diesel generator and the dump load is controlled for the tertiary compensation of the output variation of the aerogenerators.

Abstract:
PURPOSE: A neogenesis energy system capable of be applied to home and micro-grid is provided to store electric power in a battery and discharge the electric power at a peak load. CONSTITUTION: An opening and closing switch is turned off when a blackout in an electric power system occurs. The output of an inverter(20) and the connection of a distributing box(160) are blocked by the opening and closing switch. Independent operation is prevented by the switch. The output power of the inverter is supplied to multiple loads(60) according to the control by a controller and an auxiliary opening and closing switch is used for supplying the power.
