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.
The participation of wind power and energy storage in frequency regulation can significantly improve the amplitude-frequency response gain of the power system. Wind power and energy storage can significantly suppress the disturbance gain in the frequency band below the fundamental frequency.
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.
The frequency regulation capability provided by wind turbines is limited by the mechanical characteristics and the capacity of the generator set, for which insufficient frequency regulation capability needs to be supplemented by energy storage. The frequency response characteristics of the system are as described in Equation (32)
When wind turbine and energy storage do not participate in frequency regulation, i.e., Kw and Kb are both 0, according to (19), it can be calculated that the inertia time constant and primary frequency regulation coefficient of the system are only 3 s and 12 MW/Hz, which cannot meet the frequency regulation requirements of the system.
At present, although the frequency control strategy of the energy storage can improve the frequency support performance of grid-integrated wind farms, a wind-storage coordinated control strategy aiming at meeting the system frequency regulation demand is still lacking (Jin et al., 2017).
