What is Peak-Valley arbitrage?
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.
Is a retrofitted energy storage system profitable for Energy Arbitrage?
Optimising the initial state of charge factor improves arbitrage profitability by 16 %. The retrofitting scheme is profitable when the peak-valley tariff gap is >114 USD/MWh. The retrofitted energy storage system is more cost-effective than batteries for energy arbitrage.
Are energy storage systems more cost-effective than batteries for Energy Arbitrage?

However, when the proportion of reserve capacity continues to increase, the increase of reactive power compensation income is not obvious and the active output of converter is limited, which reduces the income of peak-valley arbitrage and thus the overall income is decreased.
What is energy arbitrage?
Energy arbitrage means that ESSs charge electricity during valley hours and discharge it during peak hours, thus making profits via the peak-valley electricity tariff gap [ 14 ]. Zafirakis et al. [ 15] explored the arbitrage value of long-term ESSs in various electricity markets.
What is the optimal SoC factor for Energy Arbitrage?
With the optimal value of 24 %, the remaining capacity and operational flexibility of the ESS can be properly balanced, so as to achieve the full operational cycle of energy arbitrage and the highest profit. Compared to the default value as in previous work (50 %), the optimal initial SOC factor increases the annual arbitrage profit by 16 %.
