6 FAQs about [Peak-valley electricity price energy storage system]

What is the value of energy storage?

The value of energy storage is that the prosumer will store part of the surplus generation and use it for their own use when the electricity price is high.

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.

What is energy storage for prosumers?

Due to the differences between residential and industrial & commercial users (both in terms of prices and load characteristics like voltage classes), energy storage for prosumers is only considered to be traded with similar users and the price is set according to the peak of the grid sales price.

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.

What is the virtual price of energy storage use?

In summary, the virtual price of energy storage use is set as E p s t − j = E p m + 0.01. To ensure that prosumers first sell electricity in the LEM before storing and then sending the excess to the grid, we set the virtual price of energy storage slightly lower than the feed-in tariff given by E p j − s t = E p s − g − 0.01.

Can user-side energy storage projects be profitable?

At present, user-side energy storage mainly generates income through the arbitrage of the peak-to-valley electricity price difference. This means that if the peak to valley price difference is higher than the levelized cost of using storage (LCUS), energy storage projects can be profitable.
