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 .
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.
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.
From the principle of energy storage, the most common and economically feasible options are usually pumped storage and electrochemical energy storage. Electrochemical energy storage has a fast response speed of milliseconds, which is mainly used for frequency modulation and short-term fluctuation suppression.
Electrochemical energy storage has a fast response speed of milliseconds, which is mainly used for frequency modulation and short-term fluctuation suppression. However, electrochemical energy storage has a limited number of charge/discharge cycles and a short life span, making it not suitable for large capacity and long term use.
