Customer ServiceThe scale of the energy storage system and operation strategy was related to the technical and economic performance of the coupling system , . In order to reduce the extra cost of the BESS, it is necessary to conduct the optimization research of the BESS and RE coupling system .
As can be seen from Fig. 9, the monthly electricity revenue of the BESS varies from 11,055 $ to 14,685 $, and the monthly reserve ancillary services revenue of the BESS varies from 2072 $ to 2410 $. The electricity revenue of the BESS is about five times that of the reserve ancillary services revenue. Fig. 9.
Large-scale RE connected to the grid will bring a power surge or power failure. By constructing a suitable battery energy storage system (BESS) and RE coupling system, using the BESS to store and release RE to stabilize RE's volatility and intermittent, thereby increasing RE's penetration and resilience , , .
According to the current compensation standard for reserve ancillary services, the value of this study is set as 2.25 $/MWh . Fig. 4. Annual solar irradiance in the region. Fig. 5. Annual wind speed in the region. Table 1. Parameters of peak-valley electricity price. Table 2. Main parameters of the BESS. Table 3.
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.
Taking the maximum annual net revenues of the BESS as the optimization objective, an optimization model of the BESS considering both electricity price arbitrage and reserve ancillary services is established. The annual net revenues of the BESS under different BESS capacities are evaluated.
