Some scholars have made lots of research findings on the economic benefit evaluation of battery energy storage system (BESS) for frequency and peak regulation. Most of them are about how to configure energy storage in the new energy power plants or thermal power plants to realize joint regulation.
Taking the 49.5% RE penetration system as an example, the power and capacity of the ES peaking demand at a 90% confidence level are 1358 MW and 4122 MWh, respectively, while the power and capacity of the ES frequency regulation demand are 478 MW and 47 MWh, respectively.
Li et al. mainly evaluated the economy of BESS on the thermal power side for auxiliary peak regulation and verified that BESS could effectively reduce the peak regulation cost of units; besides, BESS could achieve its own economic balance during the life cycle .
Here, we focused on this subject while conducting our research. The multi-timescale regulation capability of the power system (peak and frequency regulation, etc.) is supported by flexible resources, whose capacity requirements depend on renewable energy sources and load power uncertainty characteristics.
Energy storage power correction During peaking, ES will continuously absorb or release a large amount of electric energy. The impact of the ESED on the determination of ES capacity is more obvious. Based on this feature, we established the ES peaking power correction model with the objective of minimizing the ESED and OCGR.
In China, with the increasing power demand of users, peak load of the power system appears in winter and summer, and the peak-valley difference is constantly expanding. Thus, the pressure of peak-regulation of the grid increases continuously.
