At present, China’s small capacity energy storage power stations cannot be allowed to compete for frequency regulation services, but the establishment of auxiliary service markets such as frequency regulation and standby is conducive to guiding investment to improve the flexibility of power systems [ 19, 20, 21, 22, 23, 24, 25 ].
In this paper, a peak shaving and frequency regulation coordinated output strategy based on the existing energy storage is proposed to improve the economic problem of energy storage development and increase the economic benefits of energy storage in industrial parks.
Although the frequency regulation gain of the energy storage due to long-term multiple cycles. By comparison, under the operation of the strategy pro- Figure 12). At the same time, the problem of low peak shaving income is compensated by batteries coexist, which has a higher investme nt value. 7. Conclusions
The benefits of energy storage participating in user-side peaking and frequency regulation come from the electricity price difference of peaking, frequency regulation capacity compensation and frequency regulation mileage compensation. It is expressed as the following formula.

The model is as follows: Objective function is described as follows. of energy storage battery. Using this model, the capacity E and E of peak shaving and
Although energy storage battery each time following the signal. If 0.87 MW power is used for fre- tion benefit is lower, and the benefit of peak shaving will be obtained. Therefore, the op- timal economic results of frequency regulation and peak shaving will be obtained.
