Abstract

In order to make thermal power units better cope with the impact on the original power grid structure under the background of rapid development of new energy sources, and improve the stability, safety and economy of thermal power unit operation, based on the current research status at home and abroad, the lithium battery-flywheel control strategy and the regional dynamic primary frequency regulation model of thermal power units are proposed, and the capacity configuration scheme of flywheel-lithium battery hybrid energy storage system under a certain energy storage capacity is studied, and the simulation verification is carried out through Matlab/Simulink, Under continuous disturbance, the frequency fluctuation degree of the system is 0.00119 pu, the fluctuation amount decreases by 30.81%, the power fluctuation decreases by 43.65%, and the actual power contribution increases by 23.17%. The results show that when the thermal power unit is disturbed by external load, the frequency regulation of hybrid energy storage auxiliary thermal power unit effectively improves the operation stability and economy of thermal power unit.
