Is energy storage a profitable business model?

Although academic analysis finds that business models for energy storage are largely unprofitable, annual deployment of storage capacity is globally on the rise (IEA, 2020). One reason may be generous subsidy support and non-financial drivers like a first-mover advantage (Wood Mackenzie, 2019).

Are large-scale wind and PV power stations a viable solution to the energy crisis?

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.

How is the equivalent profit of energy storage calculated?

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.

How do energy storage devices affect power balance and grid reliability?

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.

How can wind and PV power help solve the energy crisis?

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.
