FAQS about Research on arbitrage strategies for energy storage power stations

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.

Does arbitrage value maximize the energy trade strategy?

We show that, among all strategies tested, arbitrage value maximizes for the weekly back to back energy trade strategy. Moreover we estimate the optimum size of energy storage systems in terms of arbitrage value for each different electricity market and evaluate the potential of arbitrage to support investment in the sector.

What is the arbitrage strategy?

The present arbitrage strategy is designed for the given technology attributes (including round-trip efficiency) to store the off-peak energy when the electricity price is low and releases the energy when the price is high (during the peak demand period).

Can arbitrage compensate for energy losses introduced by energy storage?

The arbitrage performance of PHS and CAES has also been evaluated in five different European electricity markets and the results indicate that arbitrage can compensate for the energy losses introduced by energy storage (Zafirakis et al., 2016).

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.
