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.
Price differences due to demand variations enable arbitrage by energy storage. Maximum daily revenue through arbitrage varies with roundtrip efficiency. Revenue of arbitrage is compared to cost of energy for various storage technologies. Breakeven cost of storage is firstly calculated with different loan periods.
Due to the increased daily electricity price variations caused by the peak and off-peak demands, energy storage systems can be utilized to generate arbitrage by charging the plants during low price periods and discharging them during high price periods.
Maximum daily revenue through arbitrage varies with roundtrip efficiency. Revenue of arbitrage is compared to cost of energy for various storage technologies. Breakeven cost of storage is firstly calculated with different loan periods. The time-varying mismatch between electricity supply and demand is a growing challenge for the electricity market.
Based on the above arbitrage revenue and capacity costs, the potential selections of energy storage technologies can be analyzed in more detail for maximum profitability once breakeven costs are achieved via attainment of technology readiness and/or system cost reductions.
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.
