6 FAQs about [Energy storage peak load adjustment fee]

How does peak-shaving affect the net load fluctuation?

As the proportion of renewable energy on the system increases, traditional generator sets need to adjust the peak and valley changes in load and the fluctuation of renewable energy output. Therefore, the peak-shaving service is mainly reflected in the adjustment of the net load fluctuation.

Does fluctuation degree of net load affect system peak-shaving cost?

It is verified that the greater the fluctuation degree of net load, the higher the total cost of system peak-shaving. The validity of this model is demonstrated for the calculation of system peak-shaving cost under different fluctuation degree of net load.

How do energy storage power stations work?

Driven by the peak and valley arbitrage profit, the energy storage power stations discharge during the peak load period and charge during the low load period. They play the role of “cutting peak and filling valley” and realize the full utilization of energy storage resources.

When are energy storage power stations in discharge state?

The energy storage power stations are in the discharge state during periods 7 to 8 and 20 to 23. In the rest of the period, the load power demand is met by renewable energy units, thermal power units and fixed output units. The deep peak-shaving grade of 300 MW, 600 MW and 1000 MW units on typical summer day are shown in Fig. 9.

Does time-of-use electricity pricing influence energy storage charging and discharging?

We call this thermal power and energy storage peaking cost optimization model as the traditional model, which does not consider the influence of time-of-use electricity pricing mechanism on energy storage charging and discharging. After model solving, the typical daily power balance bar chart of the traditional model in summer is shown in Fig. 14.
