energy storage electricity price difference calculation

How does a battery energy storage system work?

On the one hand, the battery energy storage system (BESS) is charged at the low electricity price and discharged at the peak electricity price, and the revenue is obtained through the peak-valley electricity price difference. On the other hand, extra revenue is obtained by providing reserve ancillary services to the power grid.

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. $/kWh, the flat electricity price is 0. $/kWh, and the peak electricity price is 0. $/kWh. The operation cycles (charging-discharging) of the Li-ion battery is about –.

How does energy storage make money?

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.
