This paper proposes a comprehensive control strategy for a battery energy storage system (BESS) participating in primary frequency modulation (FM) while considering the state of charge (SOC) recovery.
In order to efficiently use energy storage resources while meeting the power grid primary frequency modulation requirements, an adaptive droop coefficient and SOC balance-based primary frequency modulation control strategy for energy storage is proposed.
In recent years, electrochemical energy storage has been widely used in the field of power grid auxiliary frequency modulation because of its advantages, such as rapid action and flexible control.
According to the above information, when the coupled hybrid energy storage of the thermal power unit participates in primary frequency modulation, the output power is significantly reduced, and the safety and stability of the unit are improved to a certain extent.
Based on the above analysis, a control strategy based on cooperative frequency modulation of thermal power units and an energy storage output control system is proposed to improve the frequency stability of the power grid.
In order to ensure the effect of frequency modulation while ensuring the state of energy storage SOC and maintaining the long-term stable output of energy storage, an adaptive primary frequency modulation control strategy considering SOC feedback of energy storage battery is proposed in this paper.
