This paper introduces an optimal sizing approach for battery energy storage systems (BESS) that integrates frequency regulation via an advanced frequency droop model
To overcome these shortcomings, this paper proposes a battery SOC adaptive droop control strategy, by dynamically adjusting the droop coefficient.
The droop coefficients obtained by solving the OPF problem in various scenarios are summarized in Table 2, Table 3, and Table 4, corresponding to the adaptive droop control
The traditional battery SOC control strategy often uses a fixed droop coefficient, but this method has problems such as large DC bus voltage deviation and slow SOC equalization speed,
In the developed method, the SC droop coefficient is adaptively adjusted in a stepwise manner depending on the SC state of charge (SoC), while the battery droop
