Although large-scale energy storage directly in the network is difficult, pumped storage hydropower plants (PSHPs) have made this process possible indirectly. In fact, the main purpose of the coordinated PSHPs operation is to store the excess electric energy of the system during off-peak hours and use this energy at peak load hours [5,6].
