Abstract

To effectively enhance the active support capability for frequency in respect of the generation side of the power grid

and improve the stability

safety

and economy in respect of the operation of thermal power units

the primary frequency regulation of thermal power unit assisted by hybrid energy storage was taken as the main research object

while an optimized coordinated control strategy was proposed. Firstly

a coordinated control model of the combined system of thermal power and storage was established

and the primary frequency regulation signal of the thermal power unit was decomposed to alleviate the frequent load adjustment actions of the unit. Secondly

the energy storage control strategy was optimized. Adaptive weighting coefficients were output using a fuzzy control method

enabling smooth switching between droop control and inertia control

thus enhancing the capability of frequency regulation. Finally

a hybrid energy storage capacity optimization configuration model was constructed

and the economic benefits of different control strategies were analyzed using whale optimization algorithm. Results indicate that under continuous disturbances

the overall deviation of the system frequency of the proposed control strategy is reduced by 23.33% and 11.54% compared with that of the variable K method and droop-inertia control

respectively

while the average output of thermal power unit is decreased by 35% and 23.53%

respectively. This effectively improves the performance of frequency regulation of the combined system of thermal power and storage

enhances economic benefits

and facilitates the safe and stable operation of thermal power units.
