Performance evaluation of a variable-speed contra-rotating pump-turbine for low-head pumped hydro energy storage: An experimental study

Performance evaluation of a variable-speed contra-rotating pump-turbine for low-head pumped hydro energy storage: An experimental study

Pumped Hydro Energy Storage (PHS) provides over 90% of the global long-duration energy storage capacity, yet many regions lack the steep terrain required for conventional high-head PHS. Low-head pumped hydro energy storage (LH PHS) systems address this gap in flat topographic regions but requires ef...
