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.
Can energy storage systems generate arbitrage?
Conclusion 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.
How does reserve capacity affect peak-valley arbitrage income?
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.
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.
What are arbitrage revenue and storage technology costs?
Arbitrage revenue and storage technology costs for various loan periods as a function of storage capacity for (a) Li-ion batteries, (b) Compressed Air Energy Storage, and (c) Pumped Hydro Storage. Fig. 11 c shows the current cost of PHS per day and the arbitrage revenue with round trip efficiency of 80%.
How do price differences influence arbitrage by energy storage?
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.
