The flexibility in operation of pumped storage plants may be restricted by missing availability of pump input power. The power output of hydraulic turbines can be varied from part load to full load. For storage pumps at synchronous speed, the input power is fixed at a certain pump head and can''t be changed.

Aggregating loads and resources on both the supply and demand side of a virtual power plant (VPP) can enhance coordination between distributed generation systems and the power grid, ultimately improving the utilization rate and economic benefits of renewable energy. The energy storage system (ESS) has the added benefit of flexible demand

The levelized cost of storage (LCOS) is another metric applied in comparing alternative energy storage systems for specific energy scenarios i.e. long-term, short-term, and medium-term storage.

Energy storage systems (ESS) are becoming a key component for power systems due to their capability to store energy generation surpluses and supply them

Greater power plant flexibility and energy storage are viewed as key solutions to maintaining grid stability [2], [3], [7]. Current baseload thermal power plants have limited ability to modulate power output. The inflexibility is due largely to thermal cycling which can.
