Research on the Frequency Regulation Strategy of Large‐Scale
In this case, battery energy storage is a grid auxiliary resource with fast response and adjustable parameters, which can provide frequency support for the grid system in a short
Use Energy Storage for Primary Frequency Control in Power Grids 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.
In the end, a control framework for large-scale battery energy storage systems jointly with thermal power units to participate in system frequency regulation is constructed, and the proposed frequency regulation strategy is studied and analyzed in the EPRI-36 node model.
Current research on energy storage control strategies primarily focuses on whether energy storage systems participate in frequency regulation independently or in coordination with wind farms and photovoltaic power plants .
After reviewing the literature, it can be observed that many researchers have conducted studies on deregulated automatic generation control (AGC) systems, but only a few have focused on integrating energy storage systems (ESS) into the grid to enhance frequency response and tie-line stability.
