Energy storage power station power generation plan deviation

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.

Why do power generation operators submit their plans to a power dispatch organization?

Power generation operators submit their generation plans to the power dispatch organization before feeding electricity into the grid. This step is crucial for the operation of the power system. The submission helps the power system better allocate and dispatch power resources.

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.

Why is energy storage a viable solution to power curtailment?

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.

What is a prediction error model for photovoltaic power generation?

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.

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.
