Energy storage systems play an important role in a diverse range of industrial applications [1], [2], as either bulk energy storage or distributed transient energy buffer. Specific energy, specific power, lifetime, reliability, and safety are among the main criteria considered when picking energy storage [3] .
The hybrid energy storage system (HESS), which pairs two or more complementary energy storage components, is a solution to compensate for the shortage of single energy storage acting alone. By paring energy-intense batteries with power-intense supercapacitors (SCs), the battery-SC HESS is one widely studied practice of HESS [5] .

To achieve perfect P Grid,est estimation and to minimize the energy storage cost, it is very important for the ESS to finish each dispatching period with the same SOC as it started. Therefore, the multiplication factor that is used to adjust P Grid,est at the start of each dispatching period plays a significant role in developing the most effective
