6 FAQs about [How much energy storage should be configured in a new energy power plant]

Why is energy storage important in a power system?

Energy storage of appropriate capacity in the power system can realize peak cutting and valley filling , reduce the pressure caused by the anti-peak regulation of new energy units, and smooth the fluctuation of new energy output .

How can new energy suppliers use energy storage facilities?

New energy suppliers can use energy storage facilities by installing, renting or purchasing external services, so as to control the power output within the allowable fluctuation range.

Why is power more important than capacity?

From the perspective of capacity and power, power is more important than capacity when energy storage is mainly used to suppress fluctuations. When energy storage is used for peak regulation, the total amount of energy that can be stored is more important than power.

What is the purpose of energy storage configuration?

From the time dimension, when the short-term (minute-level) output volatility of new energy needs to be suppressed, the main purpose of energy storage configuration is to offset the penalties of output deviations.

Why should energy storage facilities be installed?

For new energy units, proper deployment of energy storage facilities can promote the consumption of excess generation, increase the option of selling electricity in the high price period, participate in the competition auxiliary service market, and improve the return on total life cycle assets.

What is the optimal strategy for new energy suppliers?

Therefore, the optimal strategy of new energy suppliers should first be to improve the prediction accuracy of bidding output, and to control fluctuations as small as possible. On this basis, through reasonable allocation of energy storage, the risk of over-limit output is further reduced.
