Then, a joint scheduling model is proposed for hybrid energy storage system to perform peak shaving and frequency regulation services to coordinate and optimize the output strategies of battery energy storage and flywheel energy storage, and minimize the total operation cost of microgrid.
However, the demand for ES capacity to enhance the peak shaving and frequency regulation capability of power systems with high penetration of RE has not been clarified at present. In this context, this study provides an approach to analyzing the ES demand capacity for peak shaving and frequency regulation.
Usually, peak shaving and frequency regulation service is a short-term scheduling problem. Considering the characteristics of MG load curve and power grid TOU price curve, this section selects the data of 12:00 for simulation research, which is both the peak load period and the peak electricity price period.
Peak load duration is 5 min, and subsidized price of peak shaving is 0.15 CNY/kWh. We assume that the capacity payment is 0.01 CNY/kWh, and set the mismatch penalty to 0.015 CNY/kWh to ensure at least 85% response capacity . The data of PJM is used for the Reg-D signal, which is shown in the Figure 4. Synthetic frequency regulation signal.
Auxiliary service effect of peak shaving. Hybrid energy storage system scheduling result of peak shaving. As can be seen from Figure 5, when the HESS only participates in peak shaving of power grid, the peak shaving effect is very obvious.
And the solving time of peak shaving, frequency regulation and joint optimization are 37.29, 36.32 and 46.28 s, respectively. Figure 5 shows the auxiliary service effect of peak shaving, and Figure 6 shows the HESS scheduling result of peak shaving.
