Compressed air energy storage (CAES) is storage for natural-gas power plants. Normally, these plants burn natural gas to heat air, which pushes a turbine in a generator. When natural gas plants are near an underground hole, like a cavern or old mine, they can use CAES. On slow days, the plant can make electricity to run a compressor that compresses outside air …
Energy storage power stations can explore a multi-channel income approach and achieve a favorable return on investment by combining “peak-valley price difference”, “capacity price”, “peak-shaving price” and “rental fee”.
Moreover, distributed energy storage is also a solution to the costly infrastructure construction of delayed power systems, and it plays a key role in improving energy efficiency and reducing carbon emissions, gradually becoming an important mainstay for the development of distributed generation, smart grid and microgrid [8, 9, 10].
This review can provide a reference value for the state-of the-art development and future research and innovation direction for energy storage configuration, expanding the application scenarios of distributed energy storage and optimizing the application effect of distributed energy storage in the power system.
Invested by distributed power users, the energy storage power station (ESPS) installed in the power distribution network can solve the operation bottlenecks of the power grid, such as power quality’s fluctuation and overload in local areas.
To sum up, the energy storage power station can consider multi-channel income mode, and obtain satisfactory return on investment through the combination of “peak-valley price difference” + “capacity price” + “peak-shaving price” + “rental fee”. 6. Conclusion
Distributed energy storage typically has a power range of kilowatts to megawatts; a short, continuous discharge time; and flexible installation locations compared to centralized energy storage, reducing the line losses and investment pressure of centralized energy storage power stations .
