French energy storage power station with two charging and two discharging functions

What is a flexible energy storage power station (fesps)?

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.

How does the Grand Maison power plant work?

The Grand Maison facility operates as a peaking power plant by pumping water from the lower reservoir to the upper reservoir for storage during periods of low electricity demand and by releasing the stored water from the upper reservoir for power generation when the electricity demand is high.

What is the operation process of power flow regulation and shared energy storage?

The operation process of power flow regulation and shared energy storage of bus 1 after obtaining the solution to the bilevel optimization operation model is depicted in Fig. 9. During the periods of 01:00–05:00 and 23:00–24:00, the load is jointly supplied by the power flow transfer and the superior power grid.
