6 FAQs about [Peak and valley electricity and thermal energy storage]

Do energy storage systems achieve the expected peak-shaving and valley-filling effect?

Abstract: In order to make the energy storage system achieve the expected peak-shaving and valley-filling effect, an energy-storage peak-shaving scheduling strategy considering the improvement goal of peak-valley difference is proposed.

Does energy storage affect peak-shaving cost?

On the other hand, references [35, 36] do not consider the impact of energy storage utilizing peak and off-peak electricity price arbitrage on the peak-shaving cost of the power system, thus failing to fully utilize the peak-shaving capabilities of energy storage.

Does a thermal power unit have a peak-shaving cost?

All thermal power units have no change in the start-stop state in 24 periods, so there is no start-stop peak-shaving cost. The consumption of renewable energy in typical winter days is shown in Fig. 13. It can be seen that there are different degrees of renewable energy abandonment during periods 12–17.

What is the winning capacity of thermal power unit deep peak-shaving?

The winning capacity of thermal power unit deep peak-shaving not only depends on its technical output limit but also is affected by the unit quotation. In this example, the thermal power unit second grade deep peak-shaving quotation is 550 yuan/MWh, while the abandonment cost of renewable energy is 500 yuan/MWh.

What is the paid peak-shaving standard of thermal power units?

The paid peak-shaving standard of thermal power units is 50 % of their rated capacity. Deep peak-shaving trading adopts unilateral centralized bidding party of thermal power enterprises to pre-clear and officially clear in real time.

What is the maximum deep peak-shaving ratio of thermal power units?

In other words, the maximum deep peak-shaving ratio of thermal power units currently stands at 65 %. From Fig. 5, we observe that as the deep peak-shaving ratio of thermal power units continues to increase, more renewable energy can be accommodated.
