6 FAQs about [Compensation measures for auxiliary services of energy storage power stations]
How Auxiliary Service of energy storage is realized?
In the case, the auxiliary service of energy storage to the power grid is mainly realized through the peak regulation of the power grid. The peak-valley price difference between various regions is about 0.36–1.06 ¥/kW·h, while the unit capacity price of sensible heat energy storage is generally 170–260 ¥/kW·h [ 36 ].
What is auxiliary service stage?
Auxiliary service stage: the excess power of the power grid is stored in the form of heat to the heat accumulator when the power consumption is low, and the cogeneration of heat and power is carried out to provide auxiliary services for the power grid when the power grid needs power for auxiliary services.
What is the allowable continuous charging capacity of the group?
The allowable continuous charging capacity of the group is not less than 212 MVar. The emergency reserve of the unit is 1 h full power equivalent operation time, and the reserve capacity of black start is 0.5 h full power equivalent operation time.
How does energy storage affect economic performance?
In summary, the economic performance of the energy storage power station is mostly affected by rental fees and the heat price, the price of auxiliary service also exerts a great impact on the economy, while the impact on the economy of cost per unit capacity of energy storage and downtime is less significant.
How does ancillary service cost affect thermal storage?
Influence of ancillary service prices and downtime The solid thermal storage may experience heat accumulation in the heating process, which may lead to temperature exceeding the critical value in some places and thermal storage life declining, resulting the shutdown maintenance is required.
What is the operation and maintenance cost of csess C2?
