Generally, thermal-based power sources are used as base load power plants, whereas gas power plants act as peak load plants due to quick delivery of power. Saikia et al. used as a gas power plant in LFC study and used as back-up sources that provide power during peak demand hour [ 3 ].
Energy storage systems are widely used for compensation of intermittent renewable energy sources and restoration of system frequency and voltage. In a conventional operation, all distributed energy storage systems are clustered into one fixed virtual power plant and their state of charges are maintained at a common value. In this
The Energy Generation is the first system benefited from energy storage services by deferring peak capacity running of plants, energy stored reserves for on-peak supply, frequency regulation, flexibility, time-shifting of production, and using more renewal resources ( NC State University, 2018, Poullikkas, 2013 ).

Abstract— Frequency stability of power systems becomes more vulnerable with the increase of solar photovoltaic (PV). Energy storage provides an option to mitigate the impact of high PV penetration. Using the U.S. Eastern Interconnection (EI) and Texas Interconnection (ERCOT) power grid models, this paper investigates the capabilities of
However, the wind power plants (WPPs) are connected to the power grid via electronic devices, which decouples the operation of VSWTG and grid frequency. Therefore, the converter-based power plants hardly contribute to the system frequency regulation and inertial response.
