摘要：
The technical requirements of wind plant frequency regulation will be drafted by power system operators with its penetration level growing high. Considering frequency response capacity of wind turbine (WT) inertia control and pitch control, we presented a wind farm-energy storage combined frequency regulation (WSCFR) method which utilizes the flexible control characteristics of energy storage system (ESS) to complement the frequency regulation operation of WT. In such a way, the short duration of inertia control and slow response of pitch control can be avoided and the frequency stability of power grid can be improved. Firstly, we established the frequency characteristics models of the corresponding frequency regulation units, such as WT, ESS, and traditional generator units. Secondly, we set up the frequency characteristics model of power system with WSCFR. Finally, the power system frequency characteristic is comparatively analyzed with different frequency regulation method including WT based FR, ESS based FR, and WSCFR based FR along with ESS power and capacity requirements. Result verifies that power and capacity of WSCFR are 67% and 11.1% of only ESS frequency regulation, which reduces the cost of ESS and improves the economic feasibility of wind plants with ESS participating to frequency regulation. ©, 2015, Science Press.
