Wind power generation apparatus and method

A wind power generation apparatus, comprising:

• an acquisition unit, a wind turbine, a generator, an electric power storage unit, and a controller, wherein;
• the acquisition unit is configured to acquire a wind power value;
• the electric power storage unit comprises a rotatable magnetic circuit and a plurality of batteries, wherein the rotatable magnetic circuit is configured to be rotated by the wind turbine and generate a magnetic field surrounding the plurality of batteries so as to generate an induced current in the and the plurality of batteries, and the electric power storage unit is connected to a grid through an inverter;
• and
• the controller is configured to control, according to the wind power value, the wind turbine to drive the generator to generate power and/or to charge the electric power storage unit according to the following scheme:
• when the wind power value is between a first wind power threshold value and a second wind power threshold value, the wind turbine only drives the generator to generate power;
• when the wind power value is greater than the second wind power threshold value, the wind turbine drives the generator and the electric power storage unit is charged by the induced current;
• when the wind power value is less than the first wind power threshold value, the wind turbine only charges the electric power storage unit by the induced electric current or only drives the electric power storage unit to output the induced electric current to the grid,
• wherein the first wind power threshold value is less than the second wind power threshold value.
