Can wind farms participate in primary frequency regulation of power system?
This manuscript provides a strategy for energy storage to coordinate wind farms to participate in primary frequency regulation of power system, and compares three frequency regulation schemes of wind power reserve, rotor inertia control and wind farm with energy storage. The comparison results show that: Wind power reserve is the least economic.
How a wind farm can improve frequency regulation?
The energy storage system can increase and decrease the output flexibly, which can improve the frequency regulation characteristics of the power system with wind power. Therefore, wind farms can build energy storage power stations with a certain capacity and undertake the task of frequency regulation.
Can wind power and energy storage participate in frequency regulation?
Currently, research on the control of wind power and energy storage to participate in frequency regulation and configuration of the energy storage capacity is at its nascent stage. Similar to wind generators, energy storage can be involved in system frequency regulation through additional differential-droop control.
What is joint frequency regulation strategy of wind-storage?
Research on joint frequency regulation strategy of wind-storage The energy storage system can increase and decrease the output flexibly, which can improve the frequency regulation characteristics of the power system with wind power.
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.
What is the difference between wind power and peak regulation?
Wind power is intermittent, random and has the character of anti-peak regulation, while the rapid growth of wind power and other renewable energy lead to the increasing pressure of peak regulation of power grid [1, 2, 3].
