6 FAQs about [Peak-valley price difference and energy storage cost]

Does energy storage affect peak-shaving cost?

On the other hand, references [35, 36] do not consider the impact of energy storage utilizing peak and off-peak electricity price arbitrage on the peak-shaving cost of the power system, thus failing to fully utilize the peak-shaving capabilities of energy storage.

What is the difference between Peak-Valley electricity price and flat electricity price?

Among the four groups of electricity prices, the peak electricity price and flat electricity price are gradually reduced, the valley electricity price is the same, and the peak-valley electricity price difference is 0.1203 $/kWh, 0.1188 $/kWh, 0.1173 $/kWh and 0.1158 $/kWh respectively. Table 5. Four groups of peak-valley electricity prices.

How much does electricity cost in a valley?

Table 1 shows the peak-valley electricity price data of the region. The valley electricity price is 0.0399 $/kWh, the flat electricity price is 0.1317 $/kWh, and the peak electricity price is 0.1587 $/kWh. The operation cycles (charging-discharging) of the Li-ion battery is about 5000–6000.

How does time-of-use electricity price affect energy storage?

To analyze this phenomenon, we can observe the charging and discharging periods of energy storage in Fig. 8, Fig. 11. The time-of-use electricity price makes the price gap between peak, flat and valley periods large, and has the role of guiding energy storage to “cut peak and fill valley”.

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).

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.
