Firstly, this paper proposes the concept of a flexible energy storage power station (FESPS) on the basis of an energy-sharing concept, which offers the dual functions of power flow regulation and energy storage. Moreover, the real-time application scenarios, operation, and implementation process for the FESPS have been analyzed herein.

During the three time periods of 03:00–08:00, 15:00–17:00, and 21:00–24:00, the loads are supplied by the renewable energy, and the excess renewable energy is stored in the FESPS or/and transferred to the other buses. Table 1. Energy storage power station.
1.1. Literature review Energy storage systems are effectively integrated into various levels of power systems, such as power generation, transmission/distribution, and residential levels, in order to facilitate capacity sharing and time-based energy transfer. This integration promotes the consumption of renewable energy .
Energy storage/reuse based on the concept of shared energy storage can fundamentally reduce the configuration capacity, investment, and operational costs for energy storage devices. Accordingly, FESPS are expected to play an important role in the construction of renewable power systems.
Shared storage service is an effective approach toward a grid with high penetration of renewable energy. The application prospects of shared energy storage services have gained widespread recognition due to the increasing use of renewable energy sources.

The Bulgarian nuclear power programme was launched in 1974 with the commissioning of the first nuclear power unit of the Kozloduy nuclear power plant. The nuclear facilities are concentrated at the Kozloduy NPP site, where six power units were built (Units 5 and 6 are in operation and Units 1–4 are in the process of decommissioning).
Nuclear power generates about a third of electricity in Bulgaria. Bulgaria's first commercial nuclear reactor began operation in 1974. The Kozloduy NPP operates two pressurized water reactors with a total output of 1906 MW. This makes Bulgaria the 21st-largest user of nuclear power in the world.
As of 2022, Bulgaria plans to construct new reactors at the existing Kozloduy site, and at Belene. Bulgaria has the Kozloduy Nuclear Power Plant with two pressurized water reactors (together 2000 MW net). Four old and unsafe VVER-440/230 reactors (4 x 408 MW net) were taken off-line in 2004 and 2007).
51% of all Bulgarians support the construction of the Belene NPP. The project for construction of new nuclear capacity on the approved new site near Kozloduy. The project for construction of nuclear capacity at the Belene site.
Efforts in May 2018 to restart the Belene project were unsuccessful. As of 2022, Bulgaria plans to construct new reactors at the existing Kozloduy site, and at Belene. Bulgaria has the Kozloduy Nuclear Power Plant with two pressurized water reactors (together 2000 MW net).

In addition, by leveraging the scaling benefits of power stations, the investment cost per unit of energy storage can be reduced to a value lower than that of the user’s investment for the distributed energy storage system, thereby reducing the total construction cost of energy storage power stations and shortening the investment payback period.
Through the incorporation of various aforementioned perspectives, the proposed system can be appropriately adapted to new power systems for a myriad of new energy sources in the future. Table 2.

“The Future of Energy Storage,” a new multidisciplinary report from the MIT Energy Initiative (MITEI), urges government investment in sophisticated analytical tools for planning, operation, and regulation of electricity systems in order to deploy and use storage efficiently.
Firstly, this paper proposes the concept of a flexible energy storage power station (FESPS) on the basis of an energy-sharing concept, which offers the dual functions of power flow regulation and energy storage. Moreover, the real-time application scenarios, operation, and implementation process for the FESPS have been analyzed herein.
Concurrently, the energy storage system can be discharged at the peak of power consumption, thereby reducing the demand for peak power supply from the power grid, which in turn reduces the required capacity of the distribution transformer; thus, the investment cost for the transformer is minimized.
