Abstract

To effectively enhance the stability of power system frequency under high penetration of wind power

and to fully utilize the frequency regulation capabilities of both wind and thermal power sources

a frequency band decomposition-based coordinated frequency regulation optimization control strategy for wind-thermal-storage was proposed. Firstly

at the system level

a wind-fire storage coordinated control model was established

and the thermal power primary frequency regulation signal was decomposed

in which the high-frequency part was responded proportionally by the wind-storage system

serving as power compensation for frequency regulation instructions of each respective response system

while the low-frequency part was responded by the thermal power. Secondly

at the unit level

wind power was designed to adopt low-overspeed deloading combined with comprehensive inertia control

while energy storage to use droop control considering the state of charge to balance their respective frequency regulation capabilities. Finally

simulation verification was carried out in different scenarios. Results show that in different simulation scenarios

the proposed strategy can increase the system minimum frequency point and reduce the output fluctuation of thermal power units.
