To address this, an effective approach is proposed, combining enhanced load frequency control (LFC) (i.e., fuzzy PID- T \({I}^{\lambda }{D}^{\mu }\)) with controlled energy storage systems.

Energy storage (ES) can mitigate the pressure of peak shaving and frequency regulation in power systems with high penetration of renewable energy (RE) caused by uncertainty and inflexibility. However, the demand for ES capacity to enhance the peak shaving and frequency regulation capability of power systems with high penetration of RE has not .

The results of the study show that the proposed battery frequency regulation control strategies can quickly respond to system frequency changes at the beginning of grid system frequency fluctuations, which improves the stability of the new power system frequency including battery energy storage.

Therefore, the economic benefit of a lithium ion battery energy storage system used for frequency regulation in a utility company is analyzed. The profit of a utility is calculated in terms of reduced amount of power purchase cost, and the results verify that the utility is able to recover their investments within the life cycle of the storage .
