6 FAQs about [Peak-valley arbitrage scheme for Palikir energy storage system]

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.

Does energy storage contribute to peaking shaving and ancillary services?

Conclusions Energy storage can participate in peaking shaving and ancillary services. It generates revenue though electricity price arbitrage and reserve service. The BESS's optimization model and the charging-discharging operation control strategy are established to make maximum revenue.

Are energy storage systems more cost-effective than batteries for Energy Arbitrage?

The retrofitted energy storage system is more cost-effective than batteries for energy arbitrage. In the context of global decarbonisation, retrofitting existing coal-fired power plants (CFPPs) is an essential pathway to achieving sustainable transition of power systems.

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.
