Wind power configuration energy storage 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.

How can wind turbines and energy storage devices improve system frequency stability?

In the power systems with high proportion of renewable power generation, wind turbines and energy storage devices can use their stored energy to provide inertia response and participate in primary frequency regulation for the improved system frequency stability.

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.

What is the primary frequency regulation requirement of energy storage system?

First of all, energy storage needs to meet the frequency regulation needs of the system. With the frequency deviation constraint determined, the primary frequency regulation requirement of the system depends on the power disturbance.

How is the energy storage capacity configured based on frequency regulation demand?

In Section 3, the energy storage capacity is configured based on the system frequency regulation demand, and a wind-storage coordinated frequency regulation control strategy is proposed, which makes reasonable use of the frequency support potential of wind power and energy storage and ensures the dynamic stability of the system frequency.
