Eastern Interconnection (EI) and Texas Interconnection (ERCOT) power grid models, this paper investigates the capabilities of using energy storage to improve frequency response under high PV penetration. A reduced second-order model is developed based on aggregation theory to simplify the multi-machine system and facilitate time-domain frequency. . This article explores the structural design, operational principles, and advanced control strategies of large-scale energy storage battery systems in secondary frequency regulation. Key innovations include dynamic power allocation between storage and conventional generators, state-of-charge (SOC). . 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.
