These issues include defining the scope of the ...
The traditional operation of PSHPs is mainly focused on satisfying the load by means of the so called hydro-thermal coordination. Thus, the water is pumped during off-peak hours when the demand is low, and it is released afterwards during peak-hours with an overall round-trip efficiency in the range of 70–80%.

Grid-scale battery energy storage systems (BESSs) are promising to solve multiple problems for future power systems. Due to the limited lifespan and high cost of BESS, there is a cost-benefit trade-off between battery effort and operational performance. Thus, we develop a battery degradation model to accurately represent the battery …
