Steel plant self-built energy storage power station

What is a self-built energy power plant?

In the self-built mode, it is assumed that the new energy power plant independently owns and manages its energy storage system, with sufficient financial and technical resources to fully cover the investment, construction, maintenance, and operational costs.

How do energy storage stations work?

In this mode, new energy power plants form a consortium to jointly invest in and build an energy storage station. Once the energy storage station is constructed, it operates as an independent entity, serving multiple new energy power plants that participated in the investment.

What is the difference between self-built and leased energy storage?

In the self-built mode, the new energy power plants themselves are both the owner and the user of the energy storage, meaning the storage system is constructed and operated by the power plants. In the leased mode, the energy storage is owned by an energy storage company, while the new energy power plant acts as the user.

Which energy storage mode is best for new energy plants?

Despite the extensive research on energy storage configuration models, most studies focus on a single mode (such as self-built, leased, or shared storage), without conducting a comprehensive analysis of all three modes to determine which provides the best benefits for new energy plants.

What is the configuration model of energy storage in self-built mode?

According to the above model, the configuration model of energy storage in the self-built mode is a mixed integer planning problem, which can be solved directly by using the Cplex solver. In the leased mode, it is assumed that the energy storage company has adequate resources to generally meet the new energy power plant’s storage needs.

Why do new energy power plants need energy storage?

Due to the uncertainty in the output of new energy power plants, there is a phenomenon of power curtailment during actual output. By configuring energy storage, new energy power plants can store the excess energy and discharge it when the output is insufficient, thus compensating for the power deficit.
