Learn MoreNew 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.
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.
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 .
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.
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.
that when the new energy unit hopes to obtain a higher deviation range, the energy storage cost paid is also higher, and this is a non-linear relationship. When the deviation increases to 10%, that is, from [5%, 10%] to [5%, 20%] or [5%, 20%] to [5%, 30%], the required energy storage configuration is higher than double.
