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.
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.
Is energy arbitrage profitability a sizing and scheduling Co-Optimisation model?
It proposes a sizing and scheduling co-optimisation model to investigate the energy arbitrage profitability of such systems. The model is solved by an efficient heuristic algorithm coupled with mathematical programming.
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 Peak-Valley price ratio?
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. It is generally believed that when the peak-valley price difference transcends 0.7 CNY/kWh, the energy storage will have the peak-valley arbitrage profit space (Li and Li, 2022).
