1. Introduction Due to global warming, the emission of CO 2, one of the greenhouse gases, has become a global concern [1, 2] 2022, the International Energy Agency (IEA) reported that CO 2 emissions from coal, oil, and natural gas were 15.5 Gt, 11.2 Gt, and 7.38 Gt, respectively [3], with fossil fuel power plants serving as a primary source of
The aggregator energy storage in this example can be divided into two categories: traditional chemical energy storage and virtual energy storage of data centers and buildings. Compared with chemical energy storage, virtual energy storage is not only more flexible, not limited by specific equipment, and more environmentally friendly.
Energy storage can reduce load peaks, fill load valleys, reduce grid load peak-to-valley differences, and obtain partial benefits. The engineering examples are shown in Table 1.
In the area of energy storage, peak shaving has been proved to be able to reduce electricity cost by 10-30%, achieved through load shedding and energy storage [16, 17].
The results show that the energy storage power station can effectively reduce the peak-to-valley difference of the load in the power system. The number of times of air abandonment and switching of charging and discharging and the number of start and stop of the unit is reduced, which effectively prolongs the service life of the unit.
