It is crucial to integrate energy storage devices within wind power and photovoltaic (PV) stations to effectively manage the impact of large-scale renewable energy generation on power balance and grid reliability. However, existing studies have not modelled the complex coupling between different types of power sources within a station.
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.
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.
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 devices can allocate a portion of their capacity to declare in the frequency regulation market while participating in the electricity market, thereby earning frequency regulation revenue.
