Abstract

The present disclosure provides a wind power generation apparatus, including a fan configured to obtain wind energy; a first generator, connected with the fan and a load and configured to convert the wind energy obtained by the fan into first electric energy and output the first electric energy to the load; a gas storage module, connected between the first generator and the load and configured to store or release gas; where when an output power of the first generator is greater than a load power of the load, the first generator drives the gas storage module to store a gas; and when the output power of the first generator is lower than the load power, the gas storage module releases a stored gas to generate second electric energy and output the second electric energy to the load.
