6 FAQs about [Output power of wind power generation system]

What is wind power generation?

Wind power generation is the process of converting wind energy into electric energy. This is achieved by using a wind generating set that absorbs wind energy with a specially designed blade, converting it to mechanical energy, which then drives a generator to produce electricity.

What is a wind power generation system (WPGS)?

The wind power generation system (WPGS) consists of a wind turbine, AC generators and power electronic devices as ancillaries for generating the output power. In WPGS, the kinetic energy of wind is converted into mechanical energy through the rotor blades of a wind turbine which is ultimately converted into electrical energy by using AC generators.

How much wind energy can be produced in the world?

Worldwide, wind energy reserves are very abundant, and the annual energy that can be developed is about 5.3 × 10 7 GWh. The wind power industry is mature, and the methods for renewable energy generation are easy to apply. Wind energy will account for 6% of global power generation by the end of 2020, with an installed capacity of 743 GW .

How can wind power output be modelled?

The probabilistic nature of wind power output can also be modelled by deriving curves using actual data of power output and wind speed of turbines deployed in a wind farm. This method requires a large number of historical data but results in accurate models [4, 24].

What is wind energy & how does it affect the world?
