As a consequence, pumped-storage hydropower plants (PSHPs) have been widely installed and operated since the 1890s, reaching an approximate worldwide installed capacity of 130 GW [1]. The traditional operation of PSHPs is mainly focused on satisfying the load by means of the so called hydro-thermal coordination.
