Firstly, a peak-valley filling time division method based on equal .

The optimization results indicate that, while meeting the load demands, BESS needs to discharge during peak and off-peak electricity price periods and charge during valley-price periods to achieve the optimal unit electricity cost for the system, thereby maximizing peak-valley price differentials.

The time-of-use electricity price makes the price gap between peak, flat and valley periods large, and has the role of guiding energy storage to “cut peak and fill valley”. The energy storage only charges during valley period and discharges during peak period.

The peak-valley arbitrage is the main profit mode of distributed energy storage system at the user side (Zhao et al., 2022). The peak-valley price ratio adopted in domestic and foreign time-of-use electricity price is mostly 3–6 times, and even reach 8–10 times in emergency cases.
