Participation in frequency regulation services can be economically rewarding for generating units. The flywheel energy storage system can effectively improve the frequency regulation capability of coal-fired units. In this paper, the improvement of the FM capability of coal-fired units in the operation of a two-area interconnected power system containing wind power is investigated, and a model of a two-area interconnected power system comprising a turbine generator, wind power, and flywheel energy storage is established. The enhancement of the FM capability of coal-fired units by adding a flywheel energy storage system is analysed. The simulation results show that adding the flywheel energy storage system improves the FM capability of the coal-fired unit to a considerable extent, and the coal-fired unit can decide the flywheel capacity it needs to be equipped with through detailed economic calculations.}, type={Article}, title={Simulation study of flywheel energy storage assisted coal-fired unit frequency regulation}, URL={http://journals.pan.pl/Content/132452/PDF/BPASTS-04501-EA.pdf}, doi={10.24425/bpasts.2024.151951}, keywords={flywheel energy storage;, coal-fired unit, frequency modulation characteristics}, }
