Selection and performance-degradation modeling of LiMO2/ Li4Ti5O1 and LiFePO4/C battery cells as suit-able energy storage systems for grid in-tegration with wind power plants: An example for the primary frequency regulation service
In power systems, load is continuously fluctuating and is difficult for slow generating units, such as coal-fired, nuclear and hydro power plants, to follow. Therefore, fast but expensive generation units like open cycle gas turbine (OCGT) are widely used to provide frequency regulation, maintaining system frequency within its specified limit. Owing to energy
