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.
It also improves the charging and discharging strategies of storage devices, extending their actual lifespan from 4.93 to 7.79 years and increasing the investment return rate of the station by 2.4%. Large-scale construction of wind and PV power has become a key strategy for dealing with the energy crisis.
In this model, the equivalent profit of energy storage in the configuration stage is calculated based on the expected profit in the operation stage. Meanwhile, the expected profit in the operation stage also depends on the optimization of energy storage capacity configuration in the configuration stage.
Reference establishes a prediction error model for photovoltaic power generation, which is able to adjust the operation of the energy storage system with the deviation of PV output, based on this basis, an economically optimal energy storage configuration method adapted to the change of PV output is proposed.
The variable operation and maintenance (O&M) costs of the wind–PV-storage system primarily consist of the variable O&M costs of the energy storage and the life cycle degradation costs of the energy storage. The calculation formula is as follows:
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.
