Wind turbine inertial energy storage

How do wind turbines control inertia?

The inertial control is realized by controlling the energy stored in the mechanical link of the wind turbine. The method of enhancing the inertia of the system by releasing the energy stored in the mechanical link of the wind turbine often requires detailed modeling of the wind power generation unit, and the control structure is complex.

Can energy storage control wind power & energy storage?

As of recently, there is not much research done on how to configure energy storage capacity and control wind power and energy storage to help with frequency regulation. Energy storage, like wind turbines, has the potential to regulate system frequency via extra differential droop control.

Why do wind turbines need an energy storage system?

To address these issues, an energy storage system is employed to ensure that wind turbines can sustain power fast and for a longer duration, as well as to achieve the droop and inertial characteristics of synchronous generators (SGs).

Can a wind turbine generate virtual inertia?

Firstly, by analyzing the characteristics of the renewable energy microgrid of the unattended offshore platform, considering the operating environment with high average wind speed at sea, the mechanical inertia in the wind turbine is selected as the energy source of virtual inertia.

What is the inertial control technology of wind power generation unit?

At present, there are many research studies on the inertial control technology of wind power generation unit, which are mainly divided into three categories: increasing energy storage equipment, adjusting maximum power tracking control, and using wind turbine mechanical links [17 – 21].

What is the inertial energy source of a wind turbine rotor?

Considering that the inertial energy source of the method used in this paper is the mechanical energy stored by the wind turbine rotor, the energy released under the premise of ensuring stable operation needs to be taken as the key influencing factor of its design.
