If combined with the technology of "extraction steam energy storage energy storage + electric heating + molten salt energy storage", the "thermoelectric decoupling" and the "zero output" peak shaving of the unit can be achieved throughout the year.

Does Qinghai have a peak shave policy?

"In addition, Qinghai is the first province to construct independent energy storage stations which participate in peak shaving. This new policy does not specify charging and discharging prices for these independent energy storage stations, nor does it specify their transaction settlement mechanism. These issues need to be further refined."

Is heat storage a solution to peak shaving in power stations?

Heat storage technology presents a promising solution to this challenge, as it significantly enhances the flexibility of peak shaving in power stations and mitigates supply-demand imbalances within power grids .

How do energy storage systems participate in peak regulation?

Energy storage systems participate in the peak regulation auxiliary service revenue from peak and off-peak power price differences and peak regulating subsidies.

Should energy storage be invested in China's peaking auxiliary services?

Therefore, direct investment in future energy storage technologies is the best choice when new technologies are already available. At this stage, the investment threshold for energy storage to involvement in China's peaking auxiliary services is 0.1068 USD/kWh.

Why should thermal power units carry out deep peak shaving?
