Profitability analysis and sizing-arbitrage optimisation of

Turning to the energy arbitrage of grid-side ESSs, researchers have investigated the profitability considering various technologies and electricity markets. 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].

Combined Source-Storage-Transmission Planning

After the peak-valley arbitrage of energy storage, the abandonment rate will increase with the increase in permeability. This also shows that with the increase in permeability, the inadaptability of fixed time-of-use electricity price will further deteriorate. However, methods the article proposed for the dynamic electricity price can

6 FAQs about [Peak-valley arbitrage of energy storage power stations in West Africa]

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 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.

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.

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).

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.

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.
