Beijing, China In the multi-station integration scenario, energy storage power stations need to be used efficiently to improve the economics of the project. In this paper, the life model of the energy storage power station, the load model of the edge data center and charging station, and the energy storage transaction model are constructed.
Large-scale construction of wind and PV power has become a key strategy for dealing with the energy crisis. However, the variability and uncertainty of large-scale renewable energy power stations pose a series of severe challenges to the power system, such as insufficient peak-shaving capacity and high curtailment rates.
In addition, considering the life loss can optimize the charging and discharging strategy of the energy storage, which extends the actual lifetime of the energy storage device from 4.93 to 7.79 years, and increases the profit of the station by 2.4%.
Therefore, power station equipped with energy storage has become a feasible solution to address the issue of power curtailment and alleviate the tension in electricity supply and demand.
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.
The overall output of the wind–PV-storage system is high during the day and low at night. The energy storage demonstrates its charge–discharge flexibility, charging during the night and at noon, and discharging at 8 am and 6 pm, achieving “low storage-high discharge” for arbitrage in the electricity market.
