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.
What is the maximum daily revenue through arbitrage?
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.
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.
Can arbitrage characteristics and breakeven costs guide energy storage system development?
The results indicate that the arbitrage characteristics and breakeven costs can be used to guide the choice of energy storage system development (capacity, effectiveness, and cost) and to determine the constraints and potential economic benefits for stakeholders who are considering investing in energy storage systems.
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.
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.
