Energy storage (ES) can mitigate the pressure of peak shaving and frequency regulation in power systems with high penetration of renewable energy (RE) caused by uncertainty and inflexibility.
Based on the Hainan case, this study analyses the economic feasibility about the battery energy storage power station cooperating with nuclear power for peak shaving, and proposes a novel feasible solution framework for the battery type selection and construction scale determination, which is also effective to other stability problems.
In view of the peak shaving problems caused by nuclear power construction, this study proposes a solution framework of battery energy storage and nuclear power combined peak shaving, which is also applicable to the grid stability problems caused by the construction of other large-scale power stations.
The benefits of energy storage participating in user-side peaking and frequency regulation come from the electricity price difference of peaking, frequency regulation capacity compensation and frequency regulation mileage compensation. It is expressed as the following formula.
However, the demand for ES capacity to enhance the peak shaving and frequency regulation capability of power systems with high penetration of RE has not been clarified at present. In this context, this study provides an approach to analyzing the ES demand capacity for peak shaving and frequency regulation.
At present, China’s small capacity energy storage power stations cannot be allowed to compete for frequency regulation services, but the establishment of auxiliary service markets such as frequency regulation and standby is conducive to guiding investment to improve the flexibility of power systems [ 19, 20, 21, 22, 23, 24, 25 ].
